9 / 16 page  Data Sheet March 19, 2009 EUE Series DC-DC Power Modules: 42-55/42-58Vdc Input; 12Vdc Output; 200/120W LINEAGE POWER 9 Test Configurations Note: Measure input reflected-ripple current with a simulated source inductance (LTEST) of 12 µH. Capacitor CS offsets possible battery impedance. Measure current as shown above. Figure 17. Input Reflected Ripple Current Test Setup. Note: Use a 1.0 µF ceramic capacitor and a 10 µF aluminum or tantalum 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 18. Output Ripple and Noise Test Setup. LOAD CONTACT AND SUPPLY II CONTACT VI(+) VI(–) VO1 DISTRIBUTION LOSSES RESISTANCE IO 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. Figure 19. Output Voltage and Efficiency Test Setup. η = VO. IO VIN. IIN x 100 % Efficiency 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., UL60950-1, CSA C22.2 No. 60950-1- 03, EN60950-1 and VDE 0805:2001-12. For the converter output to be considered meeting the requirements of safety extra-low voltage (SELV), the input must meet SELV requirements. For all input voltages, other than DC MAINS, where the input voltage is less than 60V dc, if the input meets all of the requirements for SELV, then: • The output may be considered SELV. Output voltages will remain within SELV limits even with internally-generated non-SELV voltages. Single component failure and fault tests were performed in the power converters. • One pole of the input and one pole of the output are to be grounded, or both circuits are to be kept floating, to maintain the output voltage to ground voltage within ELV or SELV limits. If the input meets extra-low voltage (ELV) requirements, then the converter’s output is considered 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. The input to these units is to be provided with a maximum 10A fast-acting fuse in the unearthed lead. |
