Resistor banks are widely used to test power systems and generator sets. Amperis offers a wide variety of load resistor banks for discharges at very reasonable prices. These products are developed with the highest quality materials, which produce an electrical load and convert the resulting power output of the source. Developed to industry standards, Amperis resistor banks are perfect for indoor or outdoor use.
In these banks, the load is generated by converting electrical energy into heat, using high power resistors such as grid resistors. It is very important that the heat is dissipated away from the load bank, either by water or air, by convection or by other forced means to avoid fouling the engine. Resistive loads simulate real-life loads during the test, such as heating, as well as the unity power factor component of magnetic loads.
The main purpose of the resistor bank is to follow the "real" or operating load accurately. Unlike the "real" load, whose value is random and unpredictable, and is likely to be dispersed, a load bank provides a fully controllable, organised and contained load. Whereas the "real" load uses the power supply and the power output of the source for its productive purposes, the load bank that uses its power output serves as a power supply to support, to test, or to protect the power supply.
Amperis resistor banks are simple to operate since they are manufactured applying the most advanced technology and top quality raw materials. They are controlled through intensive quality tests and are optimised to give the best performance. The wide range of load resistor banks for discharges are commonly used for heat dissipation or to provide stopping capability; Amperis load resistor banks for discharges are in demand for their precise designs, outstanding performance, reliability, durability, corrosion-resistant finish, and other distinctive features.

In order to save the diesel engine when the generator is running at low voltage, power resistors are used in the generator load banks. It is common practice to use power resistors as load banks to maintain batteries in industrial test facilities, in electrical laboratories, and in telecommunications facilities, among others.
A resistor bank provides an equivalent load for both the prime movers and the generators, which means that the load applied to the generator (each kilowatt) by the load bank is equal to the load applied to the prime mover. Therefore, a resistor bank removes energy from the complete system. The bank removes energy from the generator; the generator removes energy from the prime mover, and the prime mover removes energy from the fuel. All the additional energy is removed thanks to the operation of the resistive load bank: the waste heat from the exhaust gases, the coolant, the energy consumed by the accessories and the generator losses. A resistive load bank has an impact on every aspect of a generating system.
Purpose of the load resistor banks for discharges
- A resistor bank is a device or piece of equipment that develops an electrical load, applies this load to an electrical power source and also converts the resulting power output of the source.
- The main purpose of the bank is to follow the "real" or operating load accurately.
- The banks are generally used for high voltage load tests. They are of great help in industries that use generators, battery systems, UPS, etc.
- They are commonly used to test AC supplies or DC battery discharges, or UPS. The rating of the load bank is expressed in kilowatts (kw) at the rated voltage.
- They can also be used to test supplies with a limited voltage of up to 690Vac or 500Vdc. Amperis load resistor banks for discharges have been designed to ensure reliable and safe operation, with automatic tests and easy to use.
Amperis offers the best AC resistor banks for testing UPS and AC supplies. Amperis resistor banks are available in portable or fixed applications in any load bank. Amperis offers induction load banks that vary in their power factor between 0.8 and 1. The wide range of new Amperis models guarantees greater reliability, which helps to maintain the excellent reputation of Amperis products.
