SBS-4830S: Battery Capacity Tester

Constant Current DC Load Bank 20–40 Vdc 0–150 Amp / 40–60 Vdc 0–300 Amp

The only true way to be certain if your stationary batteries will perform to specification under load is to capacity test the batteries regularly.

NERC standard PRC-005-2 requires that vented lead acid and nickel cadmium (NiCd) systems be discharge tested every six (6) years and valve regulated lead acid (VRLA) batteries every three (3) years. IEEE recommends load testing stationary flooded/vented lead acid and NiCd stationary batteries every five (5) years and VRLA batteries every 12–18 months.

The SBS-4830S constant current load bank is an affordable way to perform easy and accurate load tests, including IEEE450 (vented lead acid), IEEE1106 (NiCd) and IEEE1188 (VRLA) load tests.

Exponential Power load banks are quick and easy to set up. The SBS-4830S load bank includes a touch screen to set test parameters and display voltage, current and amp hours (Ah) removed from the string during the test. Since this is a constant current load bank, the user also does not have to adjust the current during the load test.

These load banks come standard with multiple adjustable stop points and built-in protection to ensure that the batteries are never damaged due to over-discharge.

Built-in Protection Audible alarm Warning on LCD screen High temperature shutdown High voltage shutdown Over load protection Features Many unit options with wide voltage and current range Automatically discharges batteries unmanned without danger of over-discharging Continuously holds the current set throughout the test LCD screen displays real time voltage, discharge current and capacity/Ah removed Test parameters are adjustable during test without stopping test End system voltage Discharge time Discharge capacity (Ah) Units can be slaved with the SBS-8400 and/or other load banks to increase amp draw 3 adjustable stop points End system voltage Discharge time Discharge capacity (Ah)
