AC/DC Resistive Load Bank – Specialized Equipment for UPS Battery Discharge and Aging Testing

AC/DC resistive load bank is essential equipment for factory aging and performance testing of energy storage batteries, UPS and inverters. A load bank consumes power through controllable resistors to simulate real load conditions, conducting constant-power discharge, step discharge and aging tests. It evaluates power capacity, discharge curve and transfer performance to reject defective units and improve quality of energy storage and power products.

1000kW Load Bank
 

Our AC/DC resistive load bank covers low and medium-high voltage, supporting three-phase AC and multiple DC voltage levels with abundant stable power adjustment gears. The load bank integrates high-precision sampling units to record voltage, current, discharge capacity and runtime in real time. Matching software draws discharge curves and saves logs automatically for automated batch aging, greatly improving production-line testing efficiency.

The load bank adopts comprehensive safety protection: over-voltage protection, low-voltage cut-off, over-temperature protection and fan failure alarm. During battery discharge, the load bank cuts off load automatically when voltage drops below threshold to avoid over-discharge damage. If internal temperature exceeds limit, the system reduces load or shuts down to prevent fire hazards. Low temperature-coefficient alloy resistors maintain stable resistance under repeated cycles, extending service life for continuous mass production tests.

Global energy storage industry is expanding rapidly. Overseas energy storage manufacturers, battery PACK factories and UPS producers need reliable load bank for quality inspection. Without discharge testing via load bank, actual usable capacity cannot be confirmed, which may lead to capacity degradation and shutdown after deployment. Our AC/DC resistive load bank supports customized communication protocols to connect with factory MES systems. Certified products are exported worldwide.

As an original load bank manufacturer, we supply ready-made AC/DC resistive load bank as well as customized solutions according to power parameters, test procedures and workshop layout. Portable desktop, rack-mounted and cabinet-style load bank options are available for R&D labs, production aging and on-site acceptance. Manufacturers of energy storage and UPS systems can contact us for selection. Our load bank delivers stable, precise and safe testing support for full-lifecycle power product verification.
