Watt Stopper B347D-P Power Auxiliary Relay Pack 347VAC 60Hz 150mA

Description

Watt Stopper Power Pack
Part No.
B347D-P
Input Voltage: 347 VAC; 60 Hz
Ballast Amps: 15A
Output: 24 VDC; 150 mA*
*Output is 150 mA before relay is connected and 114 mA after relay is connected.
WattStopper B347D-P Power Packs provide
24VDC operating voltage to all WattStopper 24VDC
occupancy sensors and daylighting controllers.
Auxiliary Relay Packs are similar to power packs,
but only have an isolated relay and no transformer
power supply
B347D-P Power Packs consist of a transformer
and high-current relay combined in one small,
powerful package. The transformer has a primary
high voltage input and a secondary, low voltage
output (24 VDC,114 mA with relay connected).
The secondary voltage provides operating power
to WattStopper sensors. When the occupancy
sensors detect motion or daylighting sensors
detect inadequate ambient light, they electrically
close an internal circuit, which sends 24 VDC back
to the Power or Auxiliary Relay Packs that control
the lighting system.
The B347D-P Power Pack is UL 2043 plenum rated
with teflon coated low voltage leads and plenum
rated plastic. This means that the Power Packs
do not need to be installed in the junction box, but
can be installed in the plenum. They are housed in
ABS, UL-rated 94V-0 plastic enclosures.
WattStopper Power and Auxiliary Relay Packs are
designed to be flexible enough to control almost
any lighting or HVAC load. For example, B347D-P
Power Packs can control lighting circuits, selfcontained air conditioners, pumps, fans, motors,
VAV systems, motorized damper controls and
setback thermostats. They are excellent for any
application which requires high voltage switching
through low voltage controls. By linking power
packs and sensors, an almost unlimited number of
configurations can be obtained.
