PRM Models

These units are modular ferroresonant 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, see Figure 7. Hence no crowbar, fuses, or bounding circuits are needed in the output. Conventional input circuit protection is required. Ferroresonant power supplies use no noise-producing switches or oscillators. Voltage setting is independent of delicate control settings or diode references, and requires no comparators, references, or limiters. Efficiency is 65-75%.

PRM's are available in fault tolerant configurations. Consult factory for configurations to meet your requirements.

Series PRM power supplies are DIN rail mountable. In addidtion, rack mounting of Series PRM is accommodated by the following rack adapters:

Rack-mountable versions with meters, railroad-style output studs, and d-c output monitoring are options.

PRM are CE Marked per the LVD, EMC and RoHS 2 Directives. See applicable Declaration of Conformity.
