RHA 24--400V Solid State Relay, Single Phase SSR, 25A SSR Relay

Solid State Relay / SSR Relay 1) Rated voltage. 24--400V SSR Relay 2) Rated current 15A to 80A SSR 3) Zero-cross Active SSR

Solid State Relay / SSR Relay

Toky RHA series solid state relay has 2 kinds of turn-on version: Zero-cross and Random.

Zero-cross turn-on version is energised when voltage meets the zero point (about +/- 15V) and disenergised when current meets the zero point, depending on the signal control on the input circuit. Random turn-on version is energised when input valid control signal, and if no iput signal it is disenergised until the load current less than the holding current.

Technial specification:

1) Static dV/dt (Off-state): 1000V/us.

2) Dynamic dV/dt (On-state): 100V/us.

3) On-State Voltage Drop (Max.): 2V.

4) Switching voltage for zero: +-/15V.

5) Isolation: 2,000Vac minimum.

6) Operating Temperature Range: -30 to 75 C

7) Turn-On Time (Max.): 10ms.

8) Turn-Off Time (Max.): 10ms.

9) Nominal frequency: 50/60Hz;

10) Inrush current (one cycle in the power net): 700%.

We also have a wide range of accessories available to supply, including fuses and fuse holders, heat sinks and thermostats.
