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.
