DESCRIPTION
The PD-NPM-0305EP module is a wide range input voltage DC/DC converter. The module employs advanced power topology that enables
high efficiency, a wide input range and compact 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 1mA. The module is designed to perform optimally while working in conjunction with PowerDsine 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 complexity.
The PD-NPM-0305EP offers enhanced efficiency and an extended temperature range, commonly required for HDSL/xDSL repeater
applications. The Module also includes an adjustable output voltage range of ±100mV and features a plastic cover thereby reducing unit
weight. Reducing the Module’s output voltage level by a few mVolts may reduce the logic circuits and overall RT modem's power consumption.
