Single Phase Configuration
This configuration can be purchased with any or all the features available on the POWER SERIES, based on customer preference. It is intended for resistive heaters, but can also be used on transformer connected loads in the phase angle firing mode.
Three-Phase, Two Leg Configuration
This configuration is intended for zero cross ringfi only into a stable resistive heater. Typically, a
is a direct connection through a bussbar on board the POWER SERIES. Heater current monitoring and kVA options are available via the heater diagnostics option.
Three-Phase, Three Leg Configuration
All POWER SERIES options are available with this configuration.It works well with phase angle firing into a
The
Single-Phase, Multizone Configuration
This configuration is available in two and three
Heater Diagnostics
Heater diagnostics may include some or all of the features that require heater current monitoring, depending on the model selected. Heater current monitoring is only available with heater diagnostics installed on the controller. The features dependent on heater current monitoring are heater bakeout, current limiting, heater kVA monitoring, retransmit and heater monitoring alarms such as open heater, heater out of tolerance, load balance and shorted SCR detection/error. Heater diagnostics must also be installed
if you need phase angle control with current limit.
