150kW Fans Cooled Portable Variable Resistive Dummy Load Banks
Structure
1.An assembly-type enclosure contains DR series or DQ series or AS
series or other high power rating resistors ,connected in series or
in parallel.
2.The cabinet enclosure is steel structure owning good performance
in shock resistance, coated with scratch-resistance powder-coat
paint and high-temperature system to form glossy cover,insulation
and looking protective face, many colors are available.
3.There are ventilation holes in the enclosure for better
dissipation.Prevention rain and dust cover are installed on the top
of cabinet.(installed in outdoor or indoor are
available)Dissipating heat fan and temperature protection device
installation are available.
4.Portable,light-weight construction with casters,lifting eyes and
lift truck channels make is easy to maneuver.Four glove-ready
handles for moving and lifting.
5.Portable load banks are constructed using heavy gauge aluminized
steel for years of reliable service. These units are fitted with
casters or rubber shock mount feet for easy movement from one test
site to another using common pickup trucks or vans.
6.The load bank is compact and is easily transported & is equipped
with lockable casters for easy repositioning;
Introduction
1.Single-phase AC Load & three-phase AC Load are available, used
for detection and maintenance of AC equipment, loading, aging,
simulated load test, etc.
2.Rated Power Range: 1kVA - 5MVA ( other on request).
3.Current Range:0.1A - 15000A.
4.Working Voltage Range:110V-690VAC triphase or single phase.
5.Multiple safety protection functions can be designed according to
requirements:short -circuit,over-current, over-voltage,
over-load,over temperature,fan fault,audible and visual alarm
device, etc.
6.It can be designed with RS232 and RS485 to connect with PC for
remote control.
7.Air cooled type and water cooled type are available.
