The HPC family of Heater Power Controllers provides self
contained power switching for electric heater applications.
They may be controlled by many types of external temperature control
systems. All that is necessary is a
time proportioned On/Off signal. The
power output will follow the signal and automatically be Zero Cross synchronized
to minimize switching noise. The
control lines are optically isolated from the power.
All Heater Power Controllers generate heat.
This family of units eliminates the need to cool the enclosure due to
this heat by passing it to the outside via the integral heat sink.
The heat sink is mounted through the enclosure wall and thus dissipates
the heat externally. A gasket is
provided to insure a tight enclosure seal after mounting.
The HPC family is unique in that it minimizes installation
time by grouping power controllers on to one heat sink.
Each is an independent controller, with its own set of terminal blocks.
For ease of servicing, each of the SSRs may be replaced
without removing the heat sink from the enclosure. Each SSR has a protective clear plastic cover over the wiring
The terminal blocks provide a separate wiring point for each
wire, eliminating the need for multiple wires in a terminal block.
The single phase units use a one line break system, having
one Solid State Relay per heater. The three phase units use a two line break
system, having two Solid State Relays per heater. The unswitched line is passed through from L2 to H2 (single
phase) or L3 to H3 (three phase) for ease of wiring. There are models available in all standard voltages.
From 1 to 6 SSRs may be mounted on the 3 basic heatsink
sizes. In single phase units this
allows up to 6 independent controllers. In
the three phase units this allows up to 3 independent controllers.
There are optional radiused corners on the heatsink for
applications where sharp corners could be a problem. (Specify with -R suffix.)
