Load Banks

ULB’s Industrial Load Banks are ideal for routine load testing of emergency power systems including generators, uninterruptible power supplies, and turbines. These load banks can also be used for factory production line testing for manufacturers of diesel-engine gen-sets or for manufacturers of UPS (Uninterruptible Power Supplies). ULB’s load bank products offer power capacities ranging from 50 kilowatts to 5,000 kilowatts.

ULB offers a variety of standard load bank sizes which fall into two product categories, either stationary or portable. Within the stationary category, ULB offers both pad mounted and radiator mounted load banks. Within the portable category, ULB offers both caster portable and trailer mounted load banks. Resistive load banks, reactive load banks, or combination resistive/reactive load banks are available. We also offer a complete line of rack-mounted server load banks for Data Center testing and commissioning.

State-of-the-art load bank designs with standard digital controls
Single or dual-voltage designs; 50 Hz, 60 Hz or 400 Hz frequencies
Resistive, reactive or combination resistive/reactive load banks
Load banks are forced air cooled with high volume industrial blowers
Safety circuits include fan failure and over-temperature protection
Custom engineered designs are available to meet any unique application

Testek & Avtron Load Banks have been used for testing and development of new Aircraft Generators such as the B777, B787 and A380.

ULB also offers custom load bank solutions for manufacturers of Uninterruptible Power Supplies, for Manufacturers of Portable Diesel / Electrical Generators for factory production testing and for companies that require routine load testing of their standby diesel / electrical generating systems that are used as back up or emergency power.

Indoors or outdoors loading application and are available in both custom or standard resistive / reactive loads. These state of the art load banks are available in single or three phase loading capability and have variety of sizes designed but can simply be put into two categories either Stationary or Portable.
