Digital AC Portable Resistive Three-Phase Load Banks

Lead times are currently less than 3 months!

Three-phase model options range from small, portable, low-power units, to high-power, indoor & outdoor permanent resistive load banks. Models come standard with push-button manual controls as well as PC software controls offering advanced load profile solutions for working with complex testing applications.  Units are suitable for various uses including testing of generators, UPS systems, data center power systems, power supplies, HVAC systems, and other critical power sources. Single-phase load bank models also available.

Design elements incorporate a robust steel outer chassis with isolated interior chambers for control and load elements. This ensures electrical components are kept away from dirt and debris for long-life reliability in harsh test environments. Portable options include lifting eyes and caster wheels while permanent and outdoor rated units are available. All resistive load banks come with multiple built-in automatic safety shutdowns and manual override shutdown.
