Description
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.
