Solid State Control Relays
Solid State Control Relays
SST
Solid State Soft-Start
Crydom’s recognized global leadership in solid-state relays
(SSRs) is taken a step further with our extensive line of solid
state control relays. They can incorporate control circuitry,
intelligence, indication and feedback to an SSR function, further
enhancing the cost-performance benefits for the end user.
Housed in familiar electrically isolated-base packages, many
commonly used power switching/control functions are
incorporated into a single relay. Crydom’s renowned advanced
thermal management techniques are utilized to ensure ease of
mounting and cooling for long life and reliable operation.
Significant cost savings are realized from reductions in design,
volume, cooling, filed maintenance, parts count, acquisition and
inventory costs.

Models SST120 and SST240 control modules gradually apply power to the load when
energized by the control voltage. They must be used with Crydom Series 1 random
turn-on solid state relays. Consult factory for SST wiring diagrams and about use with
480 Vac loads. For a complete set (control module and solid state relay) order
10SST120, 25SST120, etc.

These “on-operate” (pull-in) time-delay solid state relays are housed in a single
industry standard package. AC output is controlled by a DC input and has an externally
adjustable time delays. Choices include models with two time-delay ranges (DSD
models: 0.1 sec to 8.3 sec.; DLD models: 1.6 sec. to 133 sec.)
