The use of an appropriate single-phase or three-phase fused disconnect or circuit breaker with this
Power Controller is required to ensure the safety of operating personnel.
HAZARDOUS VOLTAGES exist at the Power Controller Heat Sinks and at the Load, AT ALL
TIMES, when input voltage is connected. This condition exists even when the Power Controller is set
to deliver zero output.
The fused disconnect or circuit breaker must be open or OFF to perform maintenance of any kind,
including at the Load.
If this Handbook is not supplied to the End User, a WARNING statement identical to the
above should be prominently displayed in the Installation and Operation Instructions provided
to the End User.

    Operation 3PCI SCR Power Controller Series Manual 3.3. Temperature Controller A wide range of controller outputs can be used to drive the 3PCI. The range of acceptable full scale output voltages is from a minimum of 0-5 VDC to a maximum of 10 VDC. Since most controllers have a current output, the input impedance of the 3PCI on (-) and (+) is 0.05 to 10 VDC for voltage control.
