Psytronics P4803D Power Supply New

The Psytronics P4803D is a transient voltage surge suppressor designed for three phase 480 volt industrial power systems. Built by Psytronics, a Reno, Nevada manufacturer specializing in transient voltage protection systems, this unit is intended to protect connected equipment from voltage spikes, lightning induced transients, and switching surges on the line side of industrial control panels, machine tools, motor control centers, and distribution panels.

Per the nameplate, the unit is rated for 3 phase operation at 480 volts. The enclosure is a gray molded housing with a clear viewing window for the integrated status indicator light, which signals when the suppression circuitry has reached end of life and requires replacement. A contact phone number is printed on the nameplate for diagnostic reference. The housing is sealed and intended for direct mounting to a panel knockout or junction box via the integrated threaded conduit hub, with field wiring leads exiting through the bottom of the unit.

Model number P4803D is published by Psytronics for 480V 3 phase service and is a direct replacement for existing P4803D installations. Compatible applications include CNC machine tools, industrial automation panels, HVAC equipment, pumping stations, and any 480V 3 phase load requiring point of use surge protection. The manufacturer address listed on the label is 5635 Riggins Court, Unit 15, Reno, Nevada 89502.
