Series 682 1A, 250 Vrms Optically Isolated AC Solid-State Relay Part* Mil Spec Relay Description Number Number 682-1Y M28750/9-001 1A, 250 Vrms, AC Solid-State Relay (2A with Heatsink) * The Y suffix denotes parameters tested to MIL-PRF-28750 test methods. The W suffix denotes parameters tested to Teledyne specifications. FEATURES ELECTRICAL SPECIFICATIONS Relay Qualified to MIL-PRF-28750 (-55C TO +110C UNLESS OTHERWISE SPECIFIED) Zero voltage turn-on SCR output INPUT (CONTROL) SPECIFICATIONS Optical isolation Min Max Units Logic compatible input Input Current (See Figure 1) Low minimum output current V = 5 Vdc 15 mAdc IN Extremely low EMI V =32 Vdc 16 mAdc IN Low profile metal DIP package Turn-Off Voltage (Guaranteed Off) 1.5 Vdc DESCRIPTION Turn-On Voltage (Guaranteed On) 3.8 Vdc This state-of-the-art solid-state relay Reverse Voltage Protection -32 Vdc is designed for use in AC power switching applications. The output is Input Voltage Range 3.8 32 Vdc rated for 1A at 250 Vrms and can operate from 40 to 440 Hz for OUTPUT (LOAD) SPECIFICATIONS resistive and reactive loads with Min Max Units power factors as low as 0.2. Back- to-back SCRs are configured for Output Current Rating (See Figure 3) 0.2 2.0 Arms zero voltage turn-on and can handle current surges up to 8A. The Output Voltage Rating 20 250 Vrms patented circuit design assures the Frequency Range 40 440 Hz lowest possible EMI by virtually eliminating commutation spikes Output Voltage Drop -55 C 1.8 Vrms while maintaining excellent noise 1 Amp immunity. Optical isolation allows 25 C 1.6 Vrms safe control of AC loads from low 110 C 1.5 Vrms level logic circuits. The low-profile (See Figure 4) metal DIP package is hermetically sealed to withstand severe Off-State Leakage Current (250 Vac, 400 Hz) 1.0 mArms environmental conditions encountered in military and Turn-On Time 1/2 Cycle aerospace applications.
