4 Issue Date: Page 4 of 6 Report Reference # E A29-UL-1 GENERAL PRODUCT INFORMATION: CA1.0 CA1.1 Report Summary N/A CB1.0 CB1.1 Product Description Units are component type DC/DC Power Modules, and are printed wiring board or chassis mounted. They are provided with terminal pins for connection to their nominal rated dc source of supply, and output connections. The transformer in the converters is not relied on for providing any insulation. They provide functional insulation only. Output voltages remain within SELV limits, even with internally generated non-selv voltages. Refer to Enclosure - Miscellaneous for abnormal testing results which demonstrate SELV limits were not exceeded. CC1.0 CC1.1 Model Differences The following models were tested: PKL 4110A PI, PKL 4118 APIT, PKL 4316 PIT, PKL 4313 PIT, and PKL 4311 PIT. Model PKL 4110A PI represents the 4110 Series, 4119 Series, 4718 Series, 4918 Series and Models PKL 4118 PIT and PKL 4118B PIT and Model PKL 4219A PIT. Model PKL 4316 PIT represents the 4316 Series. Model PKL 4313 PIT represents the 4213 Series. Model PKL 4311 PIT represents the 4211 Series. No testing was considered necessary to add Model PKL 4219A PIT due to its similarity to Model PKL 4118 PIT. Models PKJ 4111A PI, PKJ 4119 PIT, PKJ 4216N PITM, PKJ 4316N PIT and PKJ 4316A PI were tested. All models are similar except for output voltage and current rating. The difference in output ratings is achieved by varying the number of turns on the sense inductor as well as varying the number of output filter capacitors. The "P" suffix is for positive logic for "PI's". The "T" suffix is for trim compatibility. The "PT" suffix is for positive logic of the trim compatible units. The "LA", "LB" and "LC" suffixes are for various lead length. The "M" suffix is a mechanical modification that does not have any threads for mounting auxiliary heat sinks. The Model PKJ 4216N PIT is identical to the model PKL 4316 PIT except for a different transformer (M1), current limiting resistor (R10), has different ratings due to lower output current, and the additional transistors (T3-T6), capacitors (C15-C19), and diodes (D5-D8). The Model PKJ 4316 PITM is identical to the model PKJ 4216N PIT except for lower output ratings and changes of non critical components C20, M3, R1 and R15. Models PKJ 4518 PI, PKJ 4519 PI, PKJ 4719 PI, PKJ 4910 PI, PKJ 4111 PI, PKJ 4713 PI, PKJ 4113 PI, PKJ 4113A PI are identical to model PKJ 4111A PI, except for different transformer, current limiting resistor, and output transistors or diodes.

The acceptability of these and the mating connectors relative to secureness, insulating materials, and temperature shall be considered. Consideration should be given to measuring the temperatures on power electronic components, coils, and transformer windings when the power supply is installed in the end-use equipment. All transformers employ Class A (105 C) insulation except where noted in this Report. Component Failure and SELV Reliability Tests conducted on Transformer T1 with primary to secondary shorted indicate that a reliable insulating system is not required.,, The unit should be located within an overall enclosure so that uninsulated current-carrying parts are suitably enclosed.,, The need for conducting Leakage Current Tests and Dielectric Withstand Tests are to be determined as part of the end-product evaluation.,, If the input is 75 V dc or less, then all the outputs remain SELV under normal and abnormal operating conditions. In cases where the input exceeds 60 V dc, except for model PKJ 4316A PI no additional considerations applies due to Basic Insulation is provided, for other models the following must be adhered to if the converter output shall comply to SELV:,, A. The source must be isolated by DOUBLE or REINFORCED INSULATION from the primary circuit in accordance with the standard or,, B. The source must be isolated by minimum BASIC INSULATION from the primary circuit in accordance with Subclause 2.2.4,, C. Single fault condition testing in the 60 < Vdc >75 supply circuit is to be performed with the converter to demonstrate that the output of the converter meets the requirements for SELV as per clause ,, D. If the source is a centralized d.c. power system (DC MAINS voltage), the source may be treated as a TNV-2 circuit (>60 V up to and including 80 V) then single fault testing has demonstrated compliance with SELV limits and isolation requirements equivalent to BASIC INSULATION per Subclauses , and 2.3.1b of UL Converter models PKL 4118 APIT and PKL 4118 BPIT have been evaluated for a maximum exterior base plate surface temperature of 120 C. This temperature is to be measured on the base plate of the DC/DC Converter near Q200. Airflow from an axial fan at a rate of 1.6 m/s (325 ft./min.) was directed towards T1 from a distance of 7 cm from the converter to provide laminar airflow during heating tests and cool the converter while operating under maximum normal load, to achieve a stable base plate temperature of 120 C. For model PKJ 4316A PI: The maximum temperature on the base plate above D7 shall not exceed 120 C in end system. Additional consideration shall be given during the end product investigation if the temperature exceed 120 C. For model PKJ4316A PI: A external DC fan is provided during testing. The information of DC fan are shown as follow: At 75 Vdc input, Fan RPM ; Fan Distance from Unit: 32.4 mm; Fan Location: Input side of the unit; Air-flow Direction: From Input side to Output side of the unit. At 36 Vdc input, Fan RPM ; Fan Distance from Unit: 15 cm; Fan Location: Input side of the unit; Air-flow Direction: From Input side to Output side of the unit. Functional Insulation only is considered between input and output and between input/output circuitry and base plate for all models except model PKJ 4316A PI were Basic Insulation is provided between input circuit and output circuit and between input/output circuit and base plate. Accessibility of the DC output should be considered in the end system.
