Description

The Avtron Model K711D36027 Load Bank is a duct mount style unit designed to provide a
balanced resistive load of unity power factor, at a specified 3-phase voltage. The total load
capability of the K711 Load Bank is 600 kW at 480 VAC, 3-phase, 60 Hz. Load steps are 50, 50,
100, 100, 100, 100, and 100 kW. Using the toggle switches on the control panel, any combination of
the available load steps may be selected to achieve a desired load.
An integral 480:120 volt control transformer is installed to provide 120 VAC, single phase, 60 Hz
control power.
A generator exerciser/controller is built into the Load Bank. This controller consists of a
programmable weekly timer, which will initiate a generator start signal. After an adjustable time
delay period, the Load Bank will apply load blocks of 100, 150, 150, and 200 kW sequentially.
After an adjustable exercise period, the load steps will be removed, based upon adjustable timed
settings.
The control panel contains a POWER ON-OFF switch with a POWER ON light, an OVER TEMP
light, a MASTER LOAD ON-OFF switch, a MODE SELECT MANUAL/AUTOMATIC switch, an
AUTO ON light, a clock, and individual KW LOAD STEP switches. All load step switches are the
toggle type with metal levers. The control panel also contains a FUSE for protection of the control
circuit. A Digital Metering Package is also included which monitors Volts, Amps, Frequency, and
kilowatts.
The control panel is supplied mounted in a remote wall mount enclosure. Refer to SB2196 for
dimensional information.
The Load Bank is sized for a core size of 104" high by 98" wide. Refer to SB2203 for dimensional
information.
*************************************************************
Never exceed the rated voltage as this will cause the Load Bank to
overheat.
Do not apply DC voltages as the contactors do not have arc blowout
magnets.
