Description
The digitally controlled MCxWxDx or MCxRxDx is a precision power transducer for balanced or unbalanced load system active (Watt) or reactive (VAr).

To be used in applications that require a very fast response, precision monitoring of active or reactive power. Ideal for systems for regulation and control of the load on generators, motors and inverters.

The unit measures the voltage and current true r.m.s. value, and accuracy is independent of any wave form distortion. A green LED (ON) indicates the auxiliary supply presence.

If an output is used for remote meter reading, we recommend 0-1mA for the slave indicator.

It also includes an additional RJ12 output for a DIN96 Slave Indicator (optional).

The noise-immune mA output is isolated from both the C.T. and voltage inputs and auxiliary power.

The standard models takes the auxiliary supply voltage from the monitored voltage (terminal 1 & 2).

It can also be delivered with optional separate AC or DC auxiliary voltage (terminal 26 & 27), but that must be specified when ordering.

OUTPUTS
Up to two individual very fast analogue output signals, with amplitude proportional to the measured active power (Watt) level. The noise-immune mA output is isolated from both the C.T. and voltage inputs and auxiliary power.

All standard models have one output signal, but optional models have two output signals. The analogue output is isolated from the CT, voltage inputs and auxiliary power.
