RF1B

Solid State Relays 1-Phase, Zero Cross or Instant On Switching 25 AAC, 230 VAC with LED and Built-in Transil Types RF1A, RF1B AC switching Solid State Relay Switching through back to back thyristors Long lifetime through reduced stress on output chip Operational ratings: up to 280 VAC, 25 AAC Control voltage: 5 VDC, 12 VDC, 24 VDC LED for control status indication Integrated overvoltage protection on output Opto isolation input to output 3750 VAC 100k cycles endurance test according to UL508 Pre-attached thermal interface to SSR backplate Product Description Ordering Key The RF1 series provides a compact solid state switching solution suited for confined spaces. Long life time is ensured by the use of assembly technology that reduces stresses on the power semiconductors. The RF1 series is suitable for resistive loads. The zero switching type (RF1A), switches ON when the voltage crosses zero. The instant-ON type (RF1B), switches on when the co...
