Availability: In stock
120 VAC, 25 Amp, DC Control Solid State Relay (SSR)

Production Specification

The 120D25 is a DC-controlled Power Series relay that switches 120 VAC at up to 25 A.

Power Series relays provide 4000 volts of isolation between input and output, and offer zero-voltage turn-on and zero-current turn-off. They are UL and CSA recognized and are a CE component, UKCA certified.

Lots of information on choosing and using SSRs can be found in the SSR data sheet. Also see the Manufacturers' part number cross-reference list.

This SSR carries a lifetime warranty.

NOTE: We do not recommend mounting the terminal side of the SSR to a flat PCB (printed circuit board) or other flat surface, because there may be some variation in terminal height from one terminal to another and from one SSR to another. Use the MP or P series SSRs for PCB mounting.
