General Information Reliability The failure rate () and mean time between failures (MTBF= 1/) is calculated at max output power and an operating ambient temperature (TA) of +40C. Ericsson Power Modules uses Telcordia SR-332 Issue 2 Method 1 to calculate the mean steady-state failure rate and standard deviation (). Telcordia SR-332 Issue 2 also provides techniques to estimate the upper confidence levels of failure rates based on the mean and standard deviation. Mean steady-state failure rate, Std. deviation, 804 nFailures/h 61 nFailures/h MTBF (mean value) for the BMR453 series = 1.2 Mh. MTBF at 90% confidence level = 1.0 Mh Quality Statement The products are designed and manufactured in an industrial environment where quality systems and methods like ISO 9000, Six Sigma, and SPC are intensively in use to boost the continuous improvements strategy.

IEC/EN/UL 60950-1 contains requirements to prevent injury or damage due to the following hazards: * * * * * * 3 (4) No. Electrical shock Energy hazards Fire Mechanical and heat hazards Radiation hazards Chemical hazards On-board DC/DC converters and DC/DC regulators are defined as component power supplies. As components they cannot fully comply with the provisions of any safety requirements without "Conditions of Acceptability". Clearance between conductors and between conductive parts of the component power supply and conductors on the board in the final product must meet the applicable safety requirements. Certain conditions of acceptability apply for component power supplies with limited stand-off (see Mechanical Information for further information). It is the responsibility of the installer to ensure that the final product housing these components complies with the requirements of all applicable safety standards and regulations for the final product. Component power supplies for general use should comply with the requirements in IEC 60950-1, EN 60950-1 and UL 60950-1 Safety of Information Technology Equipment. There are other more product related standards, e.g. IEEE 802.3 CSMA/CD (Ethernet) Access Method, and ETS-300132-2 Power supply interface at the input to telecommunications equipment, operated by direct current (dc), but all of these standards are based on IEC/EN/UL 60950-1 with regards to safety. Ericsson Power Modules DC/DC converters and DC/DC regulators are UL 60950-1 recognized and certified in accordance with EN 60950-1. The flammability rating for all construction parts of the products meet requirements for V-0 class material according to IEC 60695-11-10, Fire hazard testing, test flames - 50 W horizontal and vertical flame test methods. The products should be installed in the end-use equipment, in accordance with the requirements of the ultimate application. Normally the output of the DC/DC converter is considered as SELV (Safety Extra Low Voltage) and the input source must be isolated by minimum Double or Reinforced Insulation from the primary circuit (AC mains) in accordance with IEC/EN/UL 60950-1. . Rev 3 Reference EN/LZT 146 444 R1C September 2011 B (c) Ericsson AB Isolated DC/DC converters It is recommended that a slow blow fuse is to be used at the input of each DC/DC converter. If an input filter is used in the circuit the fuse should be placed in front of the input filter. In the rare event of a component problem that imposes a short circuit on the input source, this fuse will provide the following functions: * * Isolate the fault from the input power source so as not to affect the operation of other parts of the system. Protect the distribution wiring from excessive current and power loss thus preventing hazardous overheating. The galvanic isolation is verified in an electric strength test. The test voltage (Viso) between input and output is 1500 Vdc or 2250 Vdc (refer to product specification). 24 V DC systems The input voltage to the DC/DC converter is SELV (Safety Extra Low Voltage) and the output remains SELV under normal and abnormal operating conditions. 48 and 60 V DC systems If the input voltage to the DC/DC converter is 75 Vdc or less, then the output remains SELV (Safety Extra Low Voltage) under normal and abnormal operating conditions. Single fault testing in the input power supply circuit should be performed with the DC/DC converter connected to demonstrate that the input voltage does not exceed 75 Vdc. If the input power source circuit is a DC power system, the source may be treated as a TNV-2 circuit and testing has demonstrated compliance with SELV limits in accordance with IEC/EN/UL60950-1. Non-isolated DC/DC regulators The input voltage to the DC/DC regulator is SELV (Safety Extra Low Voltage) and the output remains SELV under normal and abnormal operating conditions.

See Design Note 009 for detailed information. The fundamental switching frequency is 140KHz for BMR 453 at VI = 53 V, max IO. Conducted EMI Input terminal value (typ) Test set-up Layout recommendations The radiated EMI performance of the product will depend on the PWB layout and ground layer design. It is also important to consider the stand-off of the product. If a ground layer is used, it should be connected to the output of the product and the equipment ground or chassis.

The absolute maximum continuous input voltage is 80 Vdc. Turn-off Input Voltage The product monitors the input voltage and will turn on and turn off at predetermined levels. The minimum hysteresis between turn on and turn off input voltage is 1 V. Remote Control (RC) The product is fitted with a remote control function referenced to the primary negative input connection (-In). The RC function allows the product to be turned on/off by an external device like a semiconductor or mechanical switch. The RC pin has an internal pull up resistor to internal voltage reference 18V. The external device must provide a minimum required sink current to guarantee a maximum voltage on the RC pin (see Electrical characteristics table) The standard product is provided with "negative logic" RC and will be off until the RC pin is connected to the -In. To turn off the product the RC pin should be left open, or connected to a voltage higher than 13 V referenced to -In. In situations where it is desired to have the product to power up automatically without the need for control signals or a switch, the RC pin can be wired directly to -In. Input and Output Impedance The impedance of both the input source and the load will interact with the impedance of the product. It is important that the input source has low characteristic impedance. The products are designed for stable operation without external capacitors connected to the input or output. The performance in some applications can be enhanced by addition of external capacitance as described under External Decoupling Capacitors. If the input voltage source contains significant inductance, the addition of a 22 - 100 F capacitor across the input of the product will ensure stable operation. The capacitor is not required when powering the product from an input source with an inductance below 10 H. The minimum required capacitance value depends on the output power and the input voltage. The higher output Rev Reference B C EN/LZT 146 444 R1C September 2011 (c) Ericsson AB power the higher input capacitance is needed. External Decoupling Capacitors When powering loads with significant dynamic current requirements, the voltage regulation at the point of load can be improved by addition of decoupling capacitors at the load. The most effective technique is to locate low ESR ceramic and electrolytic capacitors as close to the load as possible, using several parallel capacitors to lower the effective ESR. The ceramic capacitors will handle high-frequency dynamic load changes while the electrolytic capacitors are used to handle low frequency dynamic load changes. Ceramic capacitors will also reduce any high frequency noise at the load. It is equally important to use low resistance and low inductance PWB layouts and cabling. External decoupling capacitors will become part of the product's control loop. The control loop is optimized for a wide range of external capacitance and the maximum recommended value that could be used without any additional analysis is found in the Electrical specification. The ESR of the capacitors is a very important parameter. Stable operation is guaranteed with a verified ESR value of >10 m across the output connections. For further information please contact your local Ericsson Power Modules representative. Soft-start Power Up The soft-start control introduces a time-delay (default setting 40 ms) before allowing the output voltage to rise. The default rise time of the ramp up is 10 ms. Power-up is hence completed within 50 ms in default configuration using remote control. When starting by applying input voltage the control circuit boot-up time adds an additional 140 ms delay. Temperature Protection (OTP) The product is protected from thermal overload by an internal temperature shutdown protection. When TP1 as defined in thermal consideration section is exceeded the product will shut down. The product will make continuous attempts to start up (non-latching mode) and resume normal operation automatically when the temperature has dropped below the temperature threshold. The hysteresis is defined in general electrical specification. Note: the fault response "continue without interruption" may cause permanent damage of the product. Over Voltage Protection (OVP) The product has output over voltage protection that will shut down the product in over voltage conditions. Over Current Protection (OCP) The product includes current limiting circuitry for protection at continuous overload. The output voltage will decrease towards zero for output currents in excess of max output Ericsson Internal PRODUCT SPECIFICATION E Prepared (also subject responsible if other) No. SECSUND Approved Checked 30/1301-BMR 453 0208/014 Uen Technical Specification 11 Date BMR 453 PI series Intermediate Bus Converters2011-09-09 Input 44-75 V, Output up to 60 A / 711 W current (max IO). The product will resume normal operation after removal of the overload. The load distribution should be designed for the maximum output short circuit current specified. Fault protection recovery If one of the two modules exceeds the OVP, OCP or OTP level, the module might turn off depends on its pre-set fault response action, and the other module might not handle more current than its max capability, that will lead to both modules can not recover until the protection trig condition removed, to secure a normal operation, both modules need a reset after the fault condition removed. Pre-bias Start-up The product has a Pre-bias start up functionality and will not sink current during start up if a pre-bias source is present at the output terminals. Input Transient The products have limited ability to react on sudden input voltage changes. The module can have an output voltage deviation of 2 V when input step is applied (45 V to 53 V). This is tested with a slew rate of 0.1 V/us on the input voltage change and minimum output capacitance 100 uF. Increasing the output capacitance will improve the result.

For products mounted on a PWB without a heat sink attached, cooling is achieved mainly by conduction, from the pins to the host board, and convection, which is dependant on the airflow across the product. Increased airflow enhances the cooling of the product. The Output Current Derating graph found in the Output section for each model provides the available output current vs. ambient air temperature and air velocity at VI =53V. Rev Reference B C EN/LZT 146 444 R1C September 2011 (c) Ericsson AB measurement points may vary with different thermal design and topology. Temperatures above maximum TP1, measured at the reference point P1 are not allowed and may cause permanent damage. Position Description Max Temp.

Ambient Temperature Calculation For products with base plate the maximum allowed ambient temperature can be calculated by using the thermal resistance. 1. The power loss is calculated by using the formula ((1/) - 1) x output power = power losses (Pd). = efficiency of product. E.g. 95% = 0.95 2. Find the thermal resistance (Rth) in the Thermal Resistance graph found in the Output section for each model. Note that the thermal resistance can be significantly reduced if a heat sink is mounted on the top of the base plate. Calculate the temperature increase (T). T = Rth x Pd 3. Max allowed ambient temperature is: Max TP1 - T. E.g. BMR 453 5100/001 at 2 m/s: 1. (( Definition of product operating temperature under forced air colling The product operating temperature is used to monitor the temperature of the product, and proper thermal conditions can be verified by measuring the temperature at positions (P1, P2, P3 and P4). The temperature at these positions (TP1, TP2, TP3, TP4) should not exceed the maximum temperatures in the table below. The number of 1 ) - 1) x 396 W = 23.5 W 0.944 2. 23.5 W x 3.1C/W = 73C 3. 125 C - 73C = max ambient temperature is 52C The actual temperature will be dependent on several factors such as the PWB size, number of layers and direction of airflow.

The pin temperature is specified to maximum to 270C for maximum 10 seconds. A maximum preheat rate of 4C/s and maximum preheat temperature of 150C is suggested. When soldering by hand, care should be taken to avoid direct contact between the hot soldering iron tip and the pins for more than a few seconds in order to prevent overheating. A no-clean flux is recommended to avoid entrapment of cleaning fluids in cavities inside the product or between the product and the host board. The cleaning residues may affect long time reliability and isolation voltage. Delivery Package Information - Hole Mount Version The products are delivered in antistatic trays.
