| Solid State Relays Industrial, 1-Phase PS Types RC 24 .. -D 06, RC 44 .. -D 12 * * * * * * * AC Solid State Relay Peak switching for transformers Rated operational current: 10, 25 and 50 AACrms Non-repetitive voltage: Up to 1200 Vp Rated operational voltage: Up to 400 VACrms Input range: 4 to 32 VDC Insulation: OPTO (input-output) 4000 VACrms Product Description The peak switching relay is for switching on transformers/inductive loads in which the saturated iron core can cause severe inrush currents. The peak switching relay always switches ON at the first peak voltage in the AC sinusoidal curve after the control voltage is applied. The relay switches OFF when the current crosses zero.
