Inductive (or inductive reactive) load banks are used in conjunction with resistive load banks for testing AC supplies at non unity power factors. Most generating sets are rated at 0.8 power factor (or CosØ), so to test at rated conditions requires both resistive and inductive load.
Froment Proofloader is a load bank system that replicates working load conditions and provides a rigorous test regime for power supplies from 1kW to many MVA. Resistive, inductive or combined load banks can be customised for any application.
Resistive load banks can be used for testing AC supplies (at unity power factor) or for DC batteries discharge or UPS testing. The load bank size is expressed in kilowatts (kW) or amps (A) at the rated voltage. Froment's standard load banks can be used for testing supplies up to a voltage of 690Vac or 500Vdc.
Both resistive and inductive load are required for testing AC supplies at non unity power factors. Since most generating sets are rated at 0.8 power factor (or CosØ), testing at rated conditions is conveniently done with a combined load bank.
Load banks are constructed with switched loads and are used to electrically load electrical equipment to test it: batteries, power supplies, UPS, welding power sources, etc. They can also be used to generate electrical conditions for testing specific electrical devices, such as electromechanical relays or breakers. In that case, they become a production or troubleshooting test bench or part of it. We supply load banks from a few kilowatts to several hundred kilowatts.
Post Glover load bank resistors are systems that provide resistive electrical loads for testing critical power supply sources such as back-up or standby generators and UPS (Uninterruptible Power Supply) systems at hospitals, data centers and industrial sites. Typical applications using Load Banks include: Testing battery systems. Periodic testing of standby engine generator sets.
The Simplex Watt-Muncher is a small DC rated load bank used to test battery systems, AC to DC rectifiers and power supplies, battery chargers, UPS systems and DC generators. The Watt-Muncher provides a variable test load used to measure charge and discharge rates, response, stability and endurance. Corresponding calibrations and adjustments can be made while maintaining a constant, precise, resistive load on the power source.
The Cressall AC100 load bank is designed for on-site testing of three-phase AC generators and power supplies at 400/230V at continuous powers adjustable up to 100kW. Every model is complete with all meters, controls and power leads with quick-release in-line connectors.
