Single Phase Solid State Relays (SSR'S)
|
Tempco's Solid State Relays are a highly reliable alternative to mechanical or mercury contactors in high amperage or harsh environments. They offer years of trouble free service and millions of cycles with no moving parts to wear out. * 1 phase normally open models-- Current Ratings from 10 Amp through 75 Amp * Zero cross outputs for general applications * UL recognized and CE or CSA certified* Back-to-back SCR output stage* AC or DC control inputs* 240 or 480 Volt Outputs* Select a DC control input relay to work with a temperature control having an SSR drive output. * Choose an AC control input relay to work with a temperature control having a mechanical relay output. |
