The Model ULB-R250
is a state-of-the-art, medium capacity resistive load bank system intended for testing
and routine maintenance of stand-by generators, UPS, or other AC power sources.
Designed for outdoor installation, the load bank features vertical hot-air discharge to
keep the installation footprint to a minimum. The load bank is digitally controlled via
an on-board PLC with color touchscreen display and includes standard digital
monitoring with test data capture to a USB drive.
This load bank is a smaller version of our popular 1000 KW model and is available
in 50, 100, 150, 200 and 250 KW sizes. The ULB-R250 is compatible with other
ULB outdoor load banks and two or more load banks can be used in daisy-chain
mode with a common digital controller when higher capacity testing is required.
The load bank enclosure is rated NEMA-3R and is suitable for permanent outdoor
installation. The cabinet is constructed of heavy gauge steel with a durable polyester
powder coat finish. The cabinet has hinged access doors with lockable latches.
Cooling air is drawn in from the screened intake sides and the hot air exhaust is
directed vertically upward through a stainless steel screen on top. Forklift channels
are included in the base for easy positioning and placement. The load bank
incoming power connections are made inside the main cabinet directly to copper bus
bars.
The load bank control power is provided from a standard internal control power
transformer which derives power from the input load bus voltage. This eliminates the
need to run a separate 120 VAC utility feed to the load bank which can save
significant time and cost.
