DESCRIPTION
PD-LPM-0205 Watt DC/DC converter module designed especially remote power feeding applications. module located feeding side (LTU) operates from 60Vdc input voltage. provides isolated balanced output ±100Vdc/60 100mA. module designed support peak output power duty cycle maximum seconds duration. output configured balanced, negative positive supply rail reference earth ground. Output voltage current limits adjusted specified range adding external resistor. high precision current limiting circuit implemented output. This feature enables delivery maximum allowed current through line, while maintaining safety requirements. module also provides unique reporting signals, which required terminals, indicating output line current leakage earth ground, Overload No-Load conditions. simple identification faulty wire, different indications given positive negative leakage. unit protected against input under/over voltage, output overload shorted output unlimited period. PD-LPM-0205 designed work optimally while working conjunction with PowerDsine PD-NPM-03xx module series remote subsystem. Optimized design HDSL voice pair gain system requirements simplify integration reduce overall system cost time market.
