The module employs advanced power topology that enables high efficiency, a wide input range and pact size. It is especially designed to work as the remote (NTU) power module in remotely fed HDSL systems. The module has a shutdown mode, which when activated ("High" level on Inhibit pin), reduces the input current to sleep-mode level of approximately 1m A. The module is designed to perform optimally while working in conjunction with Power Dsine PD-LPM-0xxx module series, but may also be used in a wide range of other DC/DC applications. One of the PD-NPM-0305EP's most valuable features is its ability to work with input voltages as low as 36Vdc. This feature enables the use of the module in systems, which are locally powered from a TNV 48Vdc line. In these cases, there is no need to use any additional DC/DC converters for logic circuits supply power, thereby reducing system costs and plexity. The PD-NPM-0305EP offers enhanced efficiency and an extended temperature range, monly required for HDSL/x DSL repeater applications. The Module also includes an adjustable output voltage range of ±100m V and features a plastic cover thereby reducing unit weight. Reducing the Module’s output voltage level by a few m Volts may reduce the logic circuits and overall RT modem's power consumption.
