The PD-LPM-0102EP is a 15 Watt DC/DC converter module especially designed for HDSL/xDSL remote power feeding applications (on LTU).

The PD-LPM-0102EP operates from 36 to 72Vdc input voltage and provides two independent balanced outputs of 120V/60mA, isolated from the input.

The output voltage of PD-LPM-0102EP can be reduced, in the range of 105-120V, by adding an external resistor. Reduction of the output voltage to 105-120V may be required in order to allow for HDSL communication signal superimposing, without exceeding the maximum 120V standard limitation. A high precision current limiting circuit is implemented on each output. This feature enables delivery of maximum power through the line while maintaining the TNV safety requirements of maximum 60mA current. The module also provides report lines, which deliver information regarding unbalanced outputs (deviation of more than 20%) and overload condition of each output. The overload protection circuits on each output are independent, and allow for one output to work normally while the other is overloaded. The PD-LPM-0102EP is designed to work optimally while working in conjunction with the PowerDsine PD-NPM-03xx module series. Designed for ETSI specific requirements, the PD-LPM-0102EP simplifies integration and reduces overall system dimensions, cost and time to market.
