Model WL55



The Model WL55 series of transducers provides a relay output with a closure rate proportional to measured energy consumption (kWh). An optional analog output signal proportional to Watts is available. Voltages up to 480 Volts can be directly connected to appropriately-rated transducers.

This unit is intended to use separately-supplied current transformers with industry-standard 5A secondaries. All transducers are selfpowered from the circuit being measured.

Rugged metal enclosures and small size makes the WL55 ideal for retrofi t or initial installation 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 WL55 Diagnostics for more information.
