The Avtron LPS load bank has been renamed and is now the Avtron 7700 load bank. Please visit our new product page here for current information and pricing.

The Avtron LPS Load Bank System provides an economical and convenient means for high capacity resistive and reactive load testing of AC power systems. Many specifications and local codes demand that such testing be performed at less than unity power factor, typically 0.8 p.f. To achieve a 0.8 power factor, the LPS combines resistive load (KW) with reactive load (KVAR). This combination provides a true test of the actual generator or UPS nameplate rating (KVA) and simulates a "real world" load. The Avtron LPS System is integrated on a rugged structural skid with provisions for overhead, four point lifting.


  • Economical and convenient means for high capacity resistive and reactive loading of AC power systems such as diesel generator sets, turbines, or UPS systems
  • Consists of individual resistive and reactive load banks, and a load connection box factory mounted on rugged structural steel skid
  • All load bank exterior panels constructed out of aluminized steel for superior corrosion protection
  • Outdoor weatherproof design
  • Provision for overhead four point lifting
  • Resistive elements made from corrosion resistant chromium alloy wire and fully supported on stainless steel rods for long life
  • Reactive elements are nonsaturating single and 3 Phase iron core reactors impregnated with a high dielectric varnish
  • Resistive elements cooled by two integrally mounted fan motors each rated 10HP, 460VAC, 3 Phase, 60 Hz
  • Hot air exhaust is vertical away from personnel
  • Rugged, compact (7"x7"x2"), water resistant, lightweight Hand Held Controller communicates to load bank PLC via 200 foot cable with MS style connector
  • Controller displays Volts, Amps, Frequency, KW, KVAR, KVA, and Power Factor along with any alarm conditions
  • Hard-wired E-Stop pushbutton provided on controller
  • Single-point load connection
  • Branch circuit fusing on all load steps
  • Overtemperature protection
  • Air switches on fans electrically interlocked to remove load if airflow not sufficient to provide proper cooling
