AC Resistive
Load Banks
The benchmark for real-power testing. AR-Series resistive load banks apply a precise, fully-controllable kW load to generators, UPS systems and prime power — proving capacity, stability and protection before the system carries a live load.
Overview
Pure resistive load,
precisely controlled.
An AC resistive load bank converts electrical energy into heat through a bank of high-grade resistive elements, presenting a unity power-factor (kW) load to the source under test. It is the most direct way to verify that a generator or UPS can deliver its rated real power — and hold it.
The AR-Series spans portable single-phase test sets to containerised multi-megawatt arrays, all built on the same control architecture, the same protection philosophy and the same stainless-steel element technology engineered for a long service life under sustained full load.

Applications
Where AR-Series
earns its place.
Wherever real power must be proven before a system goes live — in the workshop, on commissioning, or in the field.
