All about control
May 1st 2008 Pump Engineering has introduced
the PE Duplex 3Z electronic control
panel for two pumps to its range of
controllers. The compact controller
is suitable for well pumps, pressure
booster sets, irrigation pumps,
sewage sump pumps and oil
transfer pumps.
The controllers enable automatic
pump rotation and include a main
isolator switch, input fuses, pump
control PCB, electronic overcurrent
protection for the pump
motors and a low voltage
transformer for supplying the
pressure switch or float switches.
Other features include inputs for
up to four float or pressure
switches with anti-contact bounce
control circuits, auto-changeover at
each pump start which spreads the
load across the two pumps, bright
LEDs to display system functions,
low or high water level alarm
(pump up or pump down), motor
protection fuses, contacts for an
alarm beacon or sounder a main
switch with door interlock. The
controller measures 340mm L x
240mm W x 170mm D and weighs
4.5kg. It is rated to IP55. More articles from Pump Engineering Ltd: |
