The output is rated for 1A at 250 Vrms and can operate from 40 to 440 Hz for resistive and reactive loads with power factors as low as 0.2. Backto-back SCRs are configured for zero voltage turn-on and can handle current surges up to 8A. The patented circuit design assures the lowest possible EMI by virtually eliminating commutation spikes while maintaining excellent noise immunity. Optical isolation allows safe control of AC loads from low level logic circuits. The low-profile metal DIP package is hermetically sealed to withstand severe environmental conditions encountered in military and aerospace applications. This relay is qualified to MIL-PRF-28750/9-001 and is available to Y screening levels.
