Zesta’s ZPAC is a solid state relay power controller
assembly. It is an electronic switching device that
switches power (current) to a load circuit when an
external DC or AC control signal is applied across its
terminals.

The ZPAC is an economical, general-purpose switching
device primarily used in heating applications. Its simple
design allows for easy installation and setup. The ZPAC
is capable of fast switching, which allows for better
heater control, resulting in improved process control and
prolonged heater life.

The ZPAC is available from stock in single-phase and
three-phase (two-leg) configurations. Custom ZPAC SSR
assemblies are also available. Contact your Zesta
technical sales representative for more information.
