Our 110V 50kW AC/DC resistive load bank is a dual‑purpose dummy load tester for power system simulation tests. Combining AC and DC testing capability in one mobile unit, this pure resistive load creates stable, harmonic‑free loading for UPS, battery, generator and telecom power commissioning. Optional data recording and multiple safety protections support on‑site acceptance and unattended long‑duration discharge testing.
Core Pain Points We Solve
Q: Need separate AC load bank and DC load bank for different tests, high procurement cost & inconvenient storage
✅ Solution: All-in-one AC/DC dual-purpose design, one unit meets both AC and DC 110V load test requirements, save budget and storage space.
Q: Many electronic loads bring harmonic interference and cannot simulate real resistive working condition
✅ Solution: Adopt pure resistive load elements, zero harmonic pollution, truly simulate actual resistive load for accurate test result.
Q: Test site changes frequently, heavy equipment hard to transport and install
✅ Solution: Mobile cabinet with heavy-duty casters and quick terminals, fast wiring and flexible relocation.
Q: Need test data and discharge curves to finish official acceptance documents
✅ Solution: Optional data logging module, real-time data recording and USB export of test report.
Q: Worried about overheating damage during long-time unattended discharge test
✅ Solution: Built-in over-temperature, overload protection + emergency stop button for safe overnight testing.
