DESCRIPTION
This state-of-the-art solid sate relay is
designed for us in ac power switching
applications. 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. Back-
to-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-R-28750/9-001 and is
available to Y screening levels.
