These fixed build, DIN rail mounted SCR units provide an inexpensive way of delivering power to resistive loads. The integral heatsink simplifies mounting and ensures adequate heat removal when mounted in a suitable enclosure.
Features: 25–100 amps, 660Vac max.; single phase zero-fired; integral heatsink design; LED input and fault indicators; internal I2t fusing (≥50A); DC, AC, and 4-20mA input versions.
