Model WL50



The WL50 series of transducers provides a relay output with a pulse rate proportional to measured energy consumption (kWh). An optional analog output signal proportional to Watts is also available. High-accuracy, split-core, current transformers are supplied with the transducers in current ranges up to 500 Amps. These transformers provide a voltage-limited secondary that eliminates the shock hazard normally associated with open-secondary leads. All transducers are self-powered from the circuit being measured. Voltages up to 480 Volts can be directly connected to appropriately-rated transducers. Rugged metal enclosures, small size, and split-core transformers make the WL50 ideal for retrofi t or initial installations in sub-metering or building management applications.

Six diagnostic LED lamps are provided to assist in verifi cation of installation. These LEDs will indicate phase sequence errors, missing phase, CT polarity reversal, etc. An additional LED indicates relay operation. Refer to Installation Diagnostics for more information.
