FEATURES/BENEFITS
•
Four independently controlled solid state
relays in a single package.
Turn-On
•
Screw type power terminals in a high
temperature plastic housing for mechanical
ruggedness.
Options (Add Suffix to Part Number) - See Page 58 for full description
•
•
•
Constant Current Input minimizes source
current requirement (standard on D input
only)
-012 EZ MountTM
-026 Non-Floating Output Terminals
Exposed ceramic baseplate for reduced
thermal resistance and best thermal
performance.
Part Number Example: EFRQ120480D55
Constructed using Teledyne’s unique
PowerthermTM process. This process yields
superior thermal impedance and power
cycling capabilities through reduced thermal
interconnections, allowing for cooler, more
reliable operation.

GENERAL DESCRIPTION
(2)
The EFRQ series 4-pole AC Solid State Relays are
designed to save space while providing independent
control of large amounts of power in four separate
circuits. Optical isolation ensures complete protection
of each relay’s circuit control elements from load
transients in each load circuit. Teledyne’s advanced
design featuring the PowerthermTM process offers
users superior thermal management resulting in
excellent performance, quality and reliability.
