Our 48V 10kW DC load bank is a harmonic-free dummy load tester for DC power and battery discharge verification. It adopts forced air cooling and comprehensive safety protections including over-temperature, over-current, under-voltage protection and emergency stop. Load stages can be switched manually. The optional data logger records real-time voltage, current and capacity, exportable via USB for test reports. Compact for indoor use, it is widely adopted by UPS manufacturers and telecom integrators.
Customer Pain Points & Solutions
❌Pain Point 1: Harmonic interference from test equipment distorts results and complicates acceptance.
✅Solution: This 48V 10kW DC load bank uses a pure resistive load design with zero harmonic distortion. It provides stable, credible load simulation during UPS acceptance, battery discharge verification and power system commissioning, helping customers avoid test disputes caused by harmonic interference.
❌Pain Point 2: Manual data recording is inefficient and difficult to document for acceptance.
✅Solution: The optional high-precision data logger records real-time voltage, current, capacity and discharge curves. Test data can be exported via USB, enabling engineers to generate formal test reports and acceptance documentation efficiently.
❌Pain Point 3: Overheating and insufficient protection increase risk during long-duration unattended tests.
✅Solution: Equipped with forced air cooling and multi-protection functions including over-temperature, over-current and under-voltage protection, plus emergency stop, this load bank improves operational safety during long continuous discharge tests.
❌Pain Point 4: Fixed load output cannot meet flexible test current or power requirements.
✅Solution: Stepwise load adjustment allows operators to switch load stages according to test requirements. This flexibility makes the unit suitable for different current ranges, capacity verification procedures and site acceptance conditions.
❌Pain Point 5: Large test equipment is complicated to install and requires dedicated space.
✅Solution: The compact indoor rack-mounted structure is designed for easy deployment in telecom rooms, data centers and test laboratories. It reduces installation complexity while maintaining stable performance for daily testing and commissioning.
❌Pain Point 6: Lack of traceable test data makes it hard to validate equipment performance or comply with acceptance criteria.
✅Solution: With configurable data logging and curve export, the load bank supports performance traceability. Recorded discharge parameters help verify UPS runtime, battery capacity and DC power system performance against technical specifications or acceptance criteria.
