System Components:
MPS-CTU Control Unit uses phase CT's and one earth-fault CT. Voltage metering and protection requires transformers for system voltages over 600 Vac. MPS-OPI Operator Interface modules can be used for metering, programming, and motor control. MPS-RTD modules can be added to monitor up to 24 temperature sensors. An MPS-DIF Differential Module and CT's can be added for differential protection.
