An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of sophisticated power architectures. To preserve maximum flexibility, internal fusing is not included, however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a time-delay fuse with a maximum rating of 5 A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer's data sheet for further information. October 5, 2015 (c)2012 General Electric Company. All rights reserved.

IO Efficiency = VIN. IIN x 100 % The power module should be connected to a low ac-impedance source. Highly inductive source impedance can affect the stability of the power module. For the test configuration in Figure 37, a 33F electrolytic capacitor (ESR<0.1 at 100kHz), mounted close to the power module helps ensure the stability of the unit. Consult the factory for further application guidelines. For safety-agency approval of the system in which the power module is used, the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standard, i.e., UL 60950-1-3, CSA C22.2 No. 60950-00, and VDE 0805:2001-12 (IEC60950-1). If the input source is non-SELV (ELV or a hazardous voltage greater than 60 Vdc and less than or equal to 75Vdc), for the module's output to be considered as meeting the requirements for safety extra-low voltage (SELV), all of the following must be true: The input source is to be provided with reinforced insulation from any other hazardous voltages, including the ac mains. One VIN pin and one VOUT pin are to be grounded, or both the input and output pins are to be kept floating. The input pins of the module are not operator accessible. Another SELV reliability test is conducted on the whole system (combination of supply source and subject module), as required by the safety agencies, to verify that under a single fault, hazardous voltages do not appear at the module's output. Note: Do not ground either of the input pins of the module without grounding one of the output pins. This may allow a non-SELV voltage to appear between the output pins and ground. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. All flammable materials used in the manufacturing of these modules are rated 94V-0, or tested to the UL60950 A.2 for reduced thickness. For input voltages exceeding -60 Vdc but less than or equal to -75 Vdc, these converters have been evaluated to the applicable requirements of BASIC INSULATION between secondary DC MAINS DISTRIBUTION input (classified as TNV-2 in Europe) and unearthed SELV outputs. The input to these units is to be provided with a maximum 5 A time-delay fuse in the ungrounded lead. October 5, 2015 (c)2012 General Electric Company. All rights reserved. Page 12 GE Data Sheet KW010/015/020/025 Series Power Modules 36 - 75Vdc Input; 1.2 to 5.0Vdc Output; 10 to 25A Output current Feature Description Remote On/Off Two remote on/off options are available. Positive logic turns the module on during a logic high voltage on the ON/OFF pin, and off during a logic low. Negative logic remote On/Off, device code suffix "1", turns the module off during a logic high and on during a logic low. Vin+ Vout+ the same output current would increase the power output of the module. Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power (Maximum rated power = Vo,set x Io,max).

Input Undervoltage Lockout Vin- Vout- Figure 40. Remote On/Off Implementation. To turn the power module on and off, the user must supply a switch (open collector or equivalent) to control the voltage (Von/off) between the ON/OFF terminal and the VIN(-) terminal (see Figure 40). Logic low is 0V Von/off 1.2V. The maximum Ion/off during a logic low is 1mA, the switch should be maintain a logic low level whilst sinking this current. During a logic high, the typical maximum Von/off generated by the module is 15V, and the maximum allowable leakage current at Von/off = 5V is 1A. At input voltages below the input undervoltage lockout limit, the module operation is disabled. The module will only begin to operate once the input voltage is raised above the undervoltage lockout turn-on threshold, VUV/ON. Once operating, the module will continue to operate until the input voltage is taken below the undervoltage turnoff threshold, VUV/OFF. Overtemperature Protection For positive logic, leave the ON/OFF pin open. For negative logic, short the ON/OFF pin to VIN(-). To provide protection under certain fault conditions, the unit is equipped with a thermal shutdown circuit. The unit will shutdown if the thermal reference point Tref (Figure 43), exceeds 125oC (typical), but the thermal shutdown is not intended as a guarantee that the unit will survive temperatures beyond its rating. The module can be restarted by cycling the dc input power for at least one second or by toggling the remote on/off signal for at least one second. If the auto-restart option (4) is ordered, the module will automatically restart upon cooldown to a safe temperature. Remote Sense Output Overvoltage Protection Remote sense minimizes the effects of distribution losses by regulating the voltage at the remote-sense connections (See Figure 41). The voltage between the remote-sense pins and the output terminals must not exceed the output voltage sense range given in the Feature Specifications table: The output over voltage protection scheme of the modules has an independent over voltage loop to prevent single point of failure. This protection feature latches in the event of over voltage across the output. Cycling the on/off pin or input voltage resets the latching protection feature. If the auto-restart option (4) is ordered, the module will automatically restart upon an internally programmed time elapsing. If not using the remote on/off feature: [VO(+) - VO(-)] - [SENSE(+) - SENSE(-)] 0.5 V Although the output voltage can be increased by both the remote sense and by the trim, the maximum increase for the output voltage is not the sum of both. The maximum increase is the larger of either the remote sense or the trim. Overcurrent Protection To provide protection in a fault (output overload) condition, the unit is equipped with internal The amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. When using remote sense and trim, the output voltage of the module can be increased, which at October 5, 2015 (c)2012 General Electric Company. All rights reserved.

At the point of current-limit inception, the unit enters hiccup mode. If the unit is not configured with auto-restart, then it will latch off following the over current condition. The module can be restarted by cycling the dc input power for at least one second or by toggling the remote on/off signal for at least one second. If the unit is configured with the auto-restart option (4), it will remain in the hiccup mode as long as the overcurrent condition exists; it operates normally, once the output current is brought back into its specified range. The average output current during hiccup is 10% IO, max. Output Voltage Programming Trimming allows the output voltage set point to be increased or decreased, this is accomplished by connecting an external resistor between the TRIM pin and either the VO(+) pin or the VO(-) pin.

This limit includes any increase in voltage due to remote-sense compensation and output voltage set-point adjustment trim. Although the output voltage can be increased by both the remote sense and by the trim, the maximum increase for the output voltage is not the sum of both. (c)2012 General Electric Company.

The amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. When using remote sense and trim, the output voltage of the module can be increased, which at the same output current would increase the power output of the module. Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power (Maximum rated power = Vo,set x Io,max). Thermal Considerations The power modules operate in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation. Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel. The thermal reference point, Tref used in the specifications is shown in Figure 43. For reliable operation this temperature should not exceed 120oC.

Pick and Place In a conventional Tin/Lead (Sn/Pb) solder process peak reflow temperatures are limited to less than 235oC. Typically, the eutectic solder melts at 183oC, wets the land, and subsequently wicks the device connection. Sufficient time must be allowed to fuse the plating on the connection to ensure a reliable solder joint. There are several types of SMT reflow technologies currently used in the industry. These surface mount power modules can be reliably soldered using natural forced convection, IR (radiant infrared), or a combination of convection/IR. For reliable soldering the solder reflow profile should be established by accurately measuring the modules CP connector temperatures. The KW010-025 modules use an open frame construction and are designed for a fully automated assembly process. The pick and place location on the module is the larger magnetic core as shown in Figure 46. The modules are fitted with a label which meets all the requirements for surface mount processing, as well as safety standards, and is able to withstand reflow temperatures of up to 300oC. The label also carries product information such as product code, serial number and the location of manufacture. 300 P eak Temp 235oC REFLOW TEMP (C) 250 Co o ling zo ne 1-4oCs -1 Heat zo ne max 4oCs -1 200 150 So ak zo ne 30-240s 100 Tlim above 205oC P reheat zo ne max 4oCs -1 50 0 Figure 46.

Even so, these modules have a relatively large mass when compared to conventional SMT components. Variables such as nozzle size, tip style, vacuum pressure and placement speed should be considered to optimize this process. The recommended nozzle diameter for reliable operation is 6mm. Oblong or oval nozzles up to 11 x 6 mm may also be used within the space available. 230 225 220 215 210 Tin Lead Soldering 205 The KW010-025 power modules (both non-Z and -Z codes) can be soldered either in a conventional Tin/Lead (Sn/Pb) process. The non-Z version of the KW010-025 modules are RoHS compliant with the lead exception. Lead based solder paste is used in the soldering process during the manufacturing of these modules. These modules can only be soldered in conventional Tin/lead (Sn/Pb) process. It is recommended that the customer review data sheets in order to customize the solder reflow profile for each application board assembly. The following instructions must be observed when soldering these units. Failure to observe these instructions may 200 October 5, 2015 0 10 20 30 Figure 48.

The non-Z version of the KW006/010 modules are RoHS compliant with the lead exception. Lead based solder paste is used in the soldering process during the manufacturing of these modules. These modules can only be soldered in conventional Tin/lead (Sn/Pb) process. Failure to observe the instructions below may result in the failure of or cause damage to the modules and can adversely affect long-term reliability. result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly. For guidance on appropriate soldering, cleaning and drying procedures, refer to GE Board Mounted Power Modules: Soldering and Cleaning Application Note (AN04-001). Pb-free Reflow Profile Power Systems will comply with J-STD-020 Rev. D (Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices) for both Pb-free solder profiles and MSL classification procedures. This standard provides a recommended forced-airconvection reflow profile based on the volume and thickness of the package (table 4-2). The suggested Pbfree solder paste is Sn/Ag/Cu (SAC). The recommended linear reflow profile using Sn/Ag/Cu solder is shown in Fig. 49. MSL Rating The KW010-025 modules have a MSL rating of 2A. Storage and Handling The recommended storage environment and handling procedures for moisture-sensitive surface mount packages is detailed in J-STD-033 Rev. A (Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive Surface Mount Devices). Moisture barrier bags (MBB) with desiccant are required for MSL ratings of 2 or greater. These sealed packages should not be broken until time of use. Once the original package is broken, the floor life of the product at conditions of 30C and 60% relative humidity varies according to the MSL rating (see J-STD-033A). The shelf life for dry packed SMT packages will be a minimum of 12 months from the bag seal date, when stored at the following conditions: < 40 C, < 90% relative humidity. Figure 49. Recommended linear reflow profile using Sn/Ag/Cu solder. Through-Hole Lead-Free Soldering Information The RoHS-compliant through-hole products use the SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant components. They are designed to be processed through single or dual wave soldering machines. The pins have an RoHS-compliant finish that is compatible with both Pb and Pb-free wave soldering processes. A maximum preheat rate of 3C/s is suggested. The wave preheat process should be such that the temperature of the power module board is kept below 210C. For Pb solder, the recommended pot temperature is 260C, while the Pb-free solder pot is 270C max. Not all RoHScompliant through-hole products can be processed with paste-through-hole Pb or Pb-free reflow process. If additional information is needed, please consult with your GE representative for more details. Post Solder Cleaning and Drying Considerations Post solder cleaning is usually the final circuit-board assembly process prior to electrical board testing.
