What are some common applications areas for this product?

Common applications include but are not limited to:

  • DC Generator Systems
  • DC Battery Systems
  • UPS Testing
  • Rectifiers
  • Power Supply
  • Power Converter Units
  • Standby Generators
  • Diesel and Gas Turbines
  • Micro-turbines
  • Wind Generators

Does the SLB-Series come with software?

Each SLB comes standard with Dataview software. This software allows us to live monitor, view test data, and export reports to Microsoft Excel

How is cell voltage monitoring accomplished?

The SLB-Series utilizes DACs (data acquisition cases) to connect to each cell. The DAC includes a wiring harness that connects to the cells. Each DAC communicates back to the SLB load bank wirelessly.

What is the power requirement for the SLB?

The exact power consumption of an SLB varies with model and discharge current, however expect the draw to be less than 9A at max current. A 15A circuit breaker is sufficient for power needs
