| AC SOLID STATE RELAY Part* Number 652-1 652-2 DESC Drawing Relay Description Number M28750/10-001 25A, 250Vrms, AC Solid State Relay M28250/10-002 Series 652 25 A, 250 VRMS OPTICALLY ISOLATED * The Y suffix denotes parameters tested to MIL-PRF-28750 test methods. The W suffix denotes parameters tested to Teledyne specifications. ELECTRICAL SPECIFICATIONS (-55C TO +110C CASE TEMPERATURE, UNLESS OTHERWISE SPECIFIED) INPUT (CONTROL) CHARACTERISTICS FEATURES * Qualified to MIL-PRF-28750 * Optical isolation Max 15 16 1.0 4 -32 4 32 Units mA mA Vdc Vdc Vdc Vdc * Zero voltage turn-on * Zero current turn-off 10 11 * Logic compatible input * Available to W or Y screening levels Min Input Current (See Figure 1) VIN = 5 Vdc VIN=32 Vdc Turn-Off Voltage (Guaranteed Off) Turn-On Voltage (Guaranteed On) Reverse Voltage Protection Input Voltage Range Typ DESCRIPTION The 652 series is an AC output solid state relay designed for power switching. This relay incorporates a sealed, optically coupled solid state relay as a zero voltage turn-on driver. The input circuit is TTL logic compatible. Output switching is accomplished by back-to-back SCRs with a built-in snubber circuit, which provides reliable switching of both resistive and reactive loads with power factors as low as 0.2. The protected drive circuitry provides high transient immunity while reducing the commutation spike for low EMI. The 652 series is housed in a sealed aluminum case to withstand severe environmental conditions encountered in military and aerospace applications. These relays are qualified to MIL-PRF-28750/10 and are available to a W or Y screening level.
