Crydom Announces Expansion of Series H1 of Panel Mounted High Voltage AC Output Solid State Relays

Crydom has expanded its Series H1 of high voltage ac output solid state relays (SSR). Complementing the successful Crydom Series H1 1200V blocking models, the new models now offer even higher levels of breakdown voltage and noise immunity (>1600V) for applications in installations where electrical transients are common and might otherwise damage less robust SSRs. The new Crydom Series H1 models include ac output ratings up to 90 amps at 660Vac, with available control voltage of 4 to 32Vdc.

The Series H1 1600V blocking models feature 4000Vac optical isolation, optional LED input status indicator, optional installed thermal pad and are available in either zero voltage or random turn-on versions. Crydom offers a variety of accessories for the Series H1 including a plastic touch safe cover, terminal lugs accepting up to 1 AWG wire, heat sinks rated from 5.0 to 0.5°C/W, and mounting hardware kits. The Series H1 is UL and cUL recognized, RoHS and China RoHS compliant, and CE certified to the EMC and Low Voltage Directives.
