ULB’s Load Banks test the operation of emergency power systems including generators, uninterruptible power supplies, and batteries in a range of environments including hospitals, data centers, manufacturing facilities, utilities, aerospace and military applications.
Our load banks are available in a range of options
AC Load Banks
For single or three-phase AC load testing for loads up to 6250KW. Available in resistive or resistive-reactive configurations, and in portable or permanent designs, suited for indoor or outdoor use.
DC Load Banks
ULB's DC Load Banks simulate the actual load a power source such as a UPS or battery will encounter during operation. Our DC Load Banks come in both portable and stationary configurations, and come with multiple safety features for load bank and operator protection.
Compact Load Banks
ULB’s compact load banks are available in both AC and DC configurations, and are designed for everyday rugged use. Each model can be contained within a carrying case (with wheels), make it easy for a single individual to carry or move. Our compact load banks are rated for upto 100 KW, and are mainly used for indoor applications. However, they may also be used outdoors when not raining or snowing.
Portable Load Banks
ULB’s range of Portable Load Banks come in configurations that can test AC or DC loads, and are meant for indoor or temporary outdoor use. Our portable load banks are provided with lifting handles/fork truck slots and caster wheels, allowing movement by a single person or a forklift.
Resistive Load Banks
Resistive load banks draw the full real power load, in kW, on the power source, help fully test its fuel, exhaust and cooling systems. ULB’s range of Resistive Load Banks can be used to test AC or DC power sources on loads up to 5000KW, and are available in portable, compact or stationary designs.
Resistive & Reactive Load Banks
Resistive-Reactive (Inductive) Load Banks are versatile load banks that can be used for a mixture of commercial loads such as lighting, heating, motors and transformers. ULB’s Resistive-Reactive Load Banks can be used to test loads up to 6250KVA.
Stationary Load Banks
ULB’s range of Stationary Load Banks are available in robust and durable designs meant for outdoor use, and can test loads up to 6250KW. The enclosures are coated with heavy gauge steel powder, and comply with NEMA Type 3R specifications, providing protection against falling rain, sleet, snow, and external ice formation.
Trailer Mounted Load Banks
ULB’s trailer mounted load banks are intended for testing and routine maintenance of stand-by generators, UPS, or other AC power sources. Designed for mobile outdoor use, our load banks are designed to keep their overall height to a minimum, allowing entry in parking garages and other areas with low height clearance.
Container Load Banks
ULB’s standard container load banks are available in 20 ft and 40 ft configurations; a 15 ft containerized version is available on request. Our container load banks are resistive, reactive or capacitive in nature, or a combination of these loads. ULB’s container load banks are designed to pack more load elements in a smaller footprint.
