KEPCO - PRM12-5 (-50) - Power Supply, DC.

These units are modular ferroresonant MIL-STD-461-compliant voltage stabilizers which obtain their source-isolated, overload-protected output from Kepco's proprietary transformer, Flux-O-Tran. This design lends itself to custom volt-ampere combinations, consult factory. The low cost, highly dependable ferroresonant stabilizing technique provides extraordinary isolation from a wide variety of source noise. The d-c output is inherently short-circuit proof and cannot expose delicate loads to over-voltage hazards.

12VDC 5Amp, 60Watt Size-D

• Modular ferroresonant voltage stabilizers
• High efficiency 65-75%.
• No overvoltage risk.
• Current limited.
