The QBVE067A0B series operate from an input voltage range of 40 to 60Vdc and provide up to 800W output power with a fully regulated output voltage of 12.0Vdc in an industry standard, DOSA compliant quarter brick. The converter incorporates digital control, synchronous rectification technology, a fully regulated control topology, and innovative packaging techniques to achieve efficiency exceeding 96.3% at 12.0Vdc output. This leads to lower power dissipations such that for many applications a heat sink is not required. Standard features include a heat plate to attach external heat sinks or contact a cold wall, on/off control, output overcurrent and over voltage protection, over temperature protection, input under and over voltage lockout. The output is fully isolated from the input, allowing versatile polarity configurations and grounding connections. Built-in filtering for both input and output minimizes the need for external filtering. * Trademark of General Electric Company # UL is a registered trademark of Underwriters Laboratories, Inc.

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 fast-acting fuse with a maximum rating of 30A in the ungrounded input lead of the power supply (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.

Highly inductive source impedance can affect the stability of the power module. For the test configuration in Figure 11, a 660F electrolytic capacitor, Cin, (ESR<0.7 at 100kHz), mounted close to the power module helps ensure the stability of the unit. Safety Considerations 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 ANSI/UL* 62368-1 and CAN/CSA+ C22.2 No. 62368-1 Recognized, DIN VDE 0868-1/A11:2017 (EN62368-1:2014/A11:2017). Note: Measure input reflected-ripple current with a simulated source inductance (LTEST) of 12 H. Capacitor CS offsets possible battery impedance. Measure current as shown above. Figure 13. Input Reflected Ripple Current Test Setup. 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) or ES1, all of the following must be true: Note: Use a 1.0 F ceramic capacitor, a 10 F aluminum or tantalum capacitor and a 750 polymer capacitor. Scope measurement should be made using a BNC socket. Position the load between 51 mm and 76 mm (2 in. and 3 in.) from the module. Figure 14. Output Ripple and Noise Test Setup. CONTACT AND DISTRIBUTION LOSSES VI(+) VO1 IO II LOAD SUPPLY VI(-) VO2 Note: All measurements are taken at the module terminals. When socketing, place Kelvin connections at module terminals to avoid measurement errors due to socket contact resistance. November 9, 2020 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 or ES1 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/ES1 voltage to appear between the output pins and ground. The power module has safety extra-low voltage (SELV) or ES1 outputs when all inputs are SELV. CONTACT RESISTANCE Figure 15. Output Voltage and Efficiency Test Setup. 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 30A fast-acting (or time-delay) fuse in the ungrounded input lead. (c) 2020 ABB.

If the overcurrent condition causes the output voltage to fall greater than 3.0V from Vo,set, the module will shut down and remain latched off. The overcurrent latch is reset by either cycling the input power or by toggling the on/off pin for one second. If the output overload condition still exists when the module restarts, it will shut down again. This operation will continue indefinitely until the overcurrent condition is corrected. A factory configured auto-restart option (with overcurrent and overvoltage auto-restart managed as a group) is also available. An auto-restart feature continually attempts to restore the operation until fault condition is cleared. Remote On/Off The module contains a standard on/off control circuit reference to the VIN(-) terminal. Two factory configured remote on/off logic options are available. Positive logic remote on/off 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 turns the module off during a logic high, and on during a logic low. Negative logic, device code suffix "1," is the factory-preferred configuration. The On/Off circuit is powered from an internal bias supply, derived from the input voltage terminals. To turn the power module on and off, the user must supply a switch to control the voltage between the On/Off terminal and the VIN(-) terminal (Von/off). The switch can be an open collector or equivalent (see Figure 14). A logic low is Von/off = -0.3V to 0.8V. The typical Ion/off during a logic low (Vin=50V, On/Off Terminal=0.3V) is 147A. The switch should maintain a logic-low voltage while sinking 200A. During a logic high, the maximum Von/off generated by the power module is 8.2V. The maximum allowable leakage current of the switch at Von/off = 2.4V is 130A. If using an external voltage source, the maximum voltage Von/off on the pin is 14.5V with respect to the VIN(-) terminal. If not using the remote on/off feature, perform one of the following to turn the unit on: For negative logic, short ON/OFF pin to VIN(-). For positive logic: leave ON/OFF pin open. Figure 16. Remote On/Off Implementation. Output Overvoltage Protection The module contains circuitry to detect and respond to November 9, 2020 output overvoltage conditions. If the overvoltage condition causes the output voltage to rise above the limit in the Specifications Table, the module will shut down and remain latched off. The overvoltage latch is reset by either cycling the input power, or by toggling the on/off pin for one second. If the output overvoltage condition still exists when the module restarts, it will shut down again. This operation will continue indefinitely until the overvoltage condition is corrected. A factory configured auto-restart option (with overcurrent and overvoltage auto-restart managed as a group) is also available. An auto-restart feature continually attempts to restore the operation until fault condition is cleared. Overtemperature Protection These modules feature an overtemperature protection circuit to safeguard against thermal damage. The circuit shuts down the module when the maximum device reference temperature is exceeded. The module will automatically restart once the reference temperature cools by ~25C. Input Under/Over voltage Lockout At input voltages above or below the input under/over voltage lockout limits, module operation is disabled. The module will begin to operate when the input voltage level changes to within the under and overvoltage lockout limits. Load Sharing For higher power requirements, the QBVE067A0B-P module offers an optional feature for parallel operation (-P Option code). This feature provides a precise forced output voltage load regulation droop characteristic. The output set point and droop slope are factory calibrated to insure optimum matching of multiple modules' load regulation characteristics. To implement load sharing, the following requirements should be followed: The VOUT(+) and VOUT(-) pins of all parallel modules must be connected together. Balance the trace resistance for each module's path to the output power planes, to insure best load sharing and operating temperature balance. VIN must remain between 40Vdc and 60Vdc for droop sharing to be functional. It is permissible to use a common Remote On/Off signal to start all modules in parallel. However if spurious shutdowns occur at startup due to very low impedance between module outputs, the modules should be started sequentially instead, waiting at least the Turn-On Delay Time + Rise Time before starting the next module. These modules contain means to block reverse current flow upon start-up, when output voltage is present from other parallel modules, thus eliminating the requirement for external output ORing devices. Modules with the -P option may automatically increase the Turn On delay, Tdelay, as specified in the Feature Specifications Table, if output voltage is present on the output bus at startup. Insure that the total load is <50% IO,MAX (for a single module) until all parallel modules have started (load full start > module Tdelay time max + Trise time). If fault tolerance is desired in parallel applications, output ORing devices should be used to prevent a single module failure from collapsing the load bus. (c) 2020 ABB.

For a given airflow and ambient temperature, the module output power is increased, until one (or more) of the components reaches its maximum derated operating temperature, as defined in IPC-9592B. This procedure is then repeated for a different airflow or ambient temperature until a family of module output derating curves is obtained. Please refer to the Application Note "Thermal Characterization Process For Open-Frame Board-Mounted Power Modules" for a detailed discussion of thermal aspects including maximum device temperatures. The power modules operate in a variety of thermal environments and sufficient cooling should be provided to help ensure reliable operation. Heat-dissipating components are mounted on the top side of the module, and heat is removed by conduction, convection and radiation to the surrounding environment. Thermal considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. The output power of the module should not exceed the rated power for the module as listed in the Ordering Information table. Furthermore, a reduction in the operating temperature of the module will result in an increase in reliability. Proper cooling can be verified by measuring the worst-case air temperature and speed just upstream of the module, and measuring or estimating the module output power. For reliable operation, the output power of the module should not exceed the rated power for the module or the derated power for the actual operating conditions as indicated in the derating curves of Figs. 19-24. A simpler but less accurate way to ensure reliable operation is to measure the thermal reference temperature (TH1) at the position indicated in Figure 17. This temperature should be limited to 100C, or a lower value for extremely high reliability. However this method limits power more than necessary for some thermal conditions; the Tref limit may be disregarded if the derating-curve method of the previous paragraph is used. Figure 18. Thermal Test Setup . Increased airflow over the module enhances the heat transfer via convection. The thermal derating of figure 17- 22 shows the maximum output current that can be delivered by each module in the indicated orientation without exceeding the maximum TH1 temperature versus local ambient temperature (TA) for several air flow conditions.

MSL Rating The QBVE067A0B modules have a MSL rating as indicated in the Device Codes table, last page of this document. 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-060A). 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. Post Solder Cleaning and Drying Considerations Post solder cleaning is usually the final circuit board assembly process prior to electrical board testing. The 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).
