Quick Overview:

Battery Capacity Tester with Monitoring

10–300 Vdc, 0–120 Amp Constant Current Smart Load Bank with Individual Cell Monitoring Capabilities for NERC and IEEE load testing

The SBS-8400 is a versatile and fully programmable, constant current discharge load bank with detailed data acquisition and display capabilities. The unit features a user-friendly touch screen menu and a complete built-in data monitoring/acquisition system when paired with wireless modules and software.

Unlike basic load banks, the SBS-8400 is a high-tech solution for easy, efficient collection of data and generation of records for archiving.

Paralleling Load Banks

Alone, the SBS-8400 has a 0–120 Amp constant current draw range. However, it is possible to parallel additional compatible load banks with the SBS-8400 to increase the current.

With the optional P/N 8400-600A DC clamp the user can discharge up to 720 Amps and the SBS-8400 will monitor the total DC current being drawn by up to two (2) additional load banks in parallel.
