DC Input SSRs
Solid state relays with a 4–30 VDC control input, driven directly by the SSR (voltage) output of PID temperature controllers. Zero-cross switching switches resistive loads silently and without contact wear.
- Series: Autonics SR1, single phase, detachable heat sink
- Current: 10 A – 75 A
- Load voltage: 24–240 VAC (SR1-12xx) or 48–480 VAC (SR1-14xx)
We recommend rating the SSR at least 1.5–2 times the load current and using a suitable heat sink.
