Load banks

Construction and execution

We produce ohmic / inductive resistor installations and their control units at the request of the customer.
The systems can be designed for AC or DC applications, or both.
Depending on the application and space layout at the customer’s premises, we use convection cooling, forced air cooling or other cooling media such as oil or water.
The power ratings can range from a few kW to several MW, divided into groups and stages that can be switched separately or used as one large resistor.
The load banks can be installed permanently or can be portable, and the load connections can feature connectors or can be connected directly to copper bus-bars.
High-precision multi-meters ensure the accurate measurement of the current parameters such as voltage, current and power. If needed, it is even possible to create a history of these values. The installation can be operated both locally and via remote control.

Applications

  • test fields
