The RPS series redundant power supplies provide a centralized power source for as many as 16 LNBs, line amplifiers, splitters or combiners. The unit is comprised of two separately fused power supply modules configured for nominal voltage of 18 or 24 VDC and has been designed for international use with an input voltage of 100-240 VAC, 50/60 Hz. The power supply modules are on individual drawers to provide easy replacement of a faulty module. Both supplies are monitored by a summary alarm which employs a serial RS-422 interface. On the rear panel, green LEDs indicate power status for each of the input ports. Each input port is capable of supplying up to 900 mA through an automatically resetting circuit limiter. Loads in excess of 900 mA will ‘trip’ the overload detection, shutting down the input port until the current demand drops below the reset threshold point.
