FEATURES/BENEFITS
•
•
Four independently controlled solid state
relays in a single package.
Screw type power terminals in a high
temperature plastic housing for mechanical
ruggedness.
Constant Current Input minimizes source
current requirement (standard on D input
only)
Exposed ceramic baseplate for reduced
thermal resistance and best thermal
performance.
Constructed using Teledyne’s unique
Powertherm
TM
process. This process yields
superior thermal impedance and power
cycling capabilities through reduced thermal
interconnections, allowing for cooler, more
reliable operation.
The logic drive circuitry section uses the
latest in reliable surface mount technology.
Certifications:
- UL and ULC Recognized File #E128555
- CE # EN60947-1

GENERAL DESCRIPTION
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 Powertherm
TM
process offers
users superior thermal management resulting in
excellent performance, quality and reliability.

NOTES:
1.)
Where overvoltage transient spikes are present,
suppression may be required. An MOV suppressor and/or
a snubber circuit across the AC terminals of the module
will provide additional transient immunity.
2.)
3.)
For 400 Hz inductive load, contact factory.
Curve for 25 amp output shown. Contact factory for other
outputs.
