The most popular load bank requests are for purely resistive models that apply load in a resistive manner only. Resistive load banks are used for testing AC supplies at unity power factors or for DC battery discharging and UPS testing. Load bank size is expressed in kW.

Resistive load banks are ruggedly constructed and designed for continuous operation and are available for all applications including small indoor load test to large outdoor static load tests. A complete power range from 5 kW to over 6000 kW that are CE and UL approved.

Inductive/Reactive load banks can be used in conjunction with existing resistive load banks for testing AC supplies at non-unity power factors. Generating sets are rated at 0.8 power factor so both resistive and Inductive load are required. The rise of solar energy and wind farms has also led to an increase popularity in inductive/ reactive only load testing.

Inductive load banks can be customised for a particular application. Three phase inductors are used that also allow single phase operation when necessary. The inductors are iron cored and continuously rated for both 50 and 60Hz operation at the maximum voltages specified.

  • Wide Voltage Range
  • Sigma Intelligent Control
  • Can link with existing resistive load banks to perform combined load test

Combined load banks test both resistive and inductive loads within a single load bank. Manufactured with the highest quality resistive elements and inductors the combined load banks will give the precision and longevity you need. The combined load bank models are available from 200-6000 kVA, so if you need a combined load bank of any size then we have you covered.

  • Rugged Construction
  • Permanent or Manoeuvrable
  • Wide Voltage Available
  • Sigma Intelligent Control Available
