PSK Series
Refrigeration Controllers
For Low and Medium Temperature Applications
Sporlan’s PSK Series electronic controllers
manage low and
medium temperature refrigeration units
by controlling com-
pressors, defrost, lights and fans.
There are several models to choose from starting with the
PSK201 with
simple logic and wiring
(for base compressor
and defrost control) to the PSK214 with
multiple I/Os and
evaporator fan management
(for complex compressor, defrost
and fan control).
A quick glance at the
3-1/2 digit display panel
during opera-
tion shows the refrigerator status; which includes an alarm icon
and temperature of the controlled space. Depending on the
model,
defrost control
is handled by compressor stop or time/
temperature based off of a real time clock.
