MDS P20 Product Overview

The MDS P20 incorporates two MDS transceivers and power supplies with automatic or manual switch-over capability. On detection of a failure, the MDS P20 switches immediately to the standby transceiver. The switch-over occurs for selectable transceiver alarm conditions. Switch-over also occurs when no valid packets are received in a programmable time-frame of 1 to 30 minutes, or upon loss of power to the operating radio. An internal back-up battery is provided in AC-powered models for continued operation during a loss of primary power.

The MDS P20 Redundant Station is easily maintained with Standard MDS transceivers that are field-replaceable. The MDS P20 is packaged in a low-profile (2U) metal case that may be placed on a tabletop or rack mounted.

Why Consider a GE MDS Master Station Series Solution?
