RDA-PSM

 12 VDC 2.5 Amp Power Supply Module

The RDA-PSM Power Supply is a 30 W module providing an un-regulated 
output of 12 VDC at 2.5 Amps. The power supply module is designed for 
use with the RDA series of Radia enclosures. The RDA-PSM is used to 
supply extra power to Radia control cards when the amount of power 
required to drive the modules exceeds the 300 mA supply on each 
controller. The module's voltage and current ratings are CE, UL, and C-UL 
approved.
