DESCRIPTION
PD-LPM-0102EP Watt DC/DC converter module especially designed HDSL/xDSL remote power feeding applications LTU). module operates from 72Vdc input voltage provides independent balanced outputs 120V/60mA, isolated from input. output voltage reduced, range 105-120V, adding external resistor. Reduction output voltage 105-120V required order allow HDSL communication signal superimposing, without exceeding maximum 120V standard limitation. high precision current limiting circuit implemented each output. This feature enables delivery maximum power through line while maintaining safety requirements maximum 60mA current. module also provides report lines, which deliver information regarding unbalanced outputs (deviation more than 20%) overload condition each output. overload protection circuits each output independent, allow output work normally while other overloaded. PD-LPM-0102EP designed work optimally while working conjunction with PowerDsine PD-NPM-03xx module series. Designed ETSI specific requirements, PDLPM-0102EP simplifies integration reduces overall system dimensions, cost time market.

Unless otherwise stated, data refers both Output Output Connecting resistor, Rext, between sets output voltage. output voltages 110V, Rext 11.5K resistor. When left open (Rext output voltage maximum value. Setting effects both Output Output output stage acts current source. When output current reaches threshold, overload circuit will detect 5-8V drop below nominal value. output stage acts current source when reaches current limit level. When output voltage falls below threshold level, output stage disconnected order reduce heat dissipation. unit reverts normal operation once overload condition removed. Overload condition output does effect other output. module designed meet EN55022 Class Standard with external filter. filter design recommendations, refer PowerDsine xDSL Power Modules Application Note. When connecting outputs parallel achieve single 120V/120mA output, automatic recovery from overload shutdown will occur only after total consumed output current drops below 60mA.
