This VILVA 200kW 450A DC resistive load bank provides harmonic-free discharge testing for energy storage packs, UPS and DC power supplies. Featuring stepped load control, multi-safety protection and forced air cooling, it supports reliable unattended capacity verification. Optional data logging captures test data and exports curves for official acceptance.
Pain Points & Solutions
❌Electronic active loads introduce harmonic distortion, failing to satisfy strict site acceptance specifications for power systems and battery banks.
✅It adopts pure resistive loading topology with linear, distortion-free loading characteristics, fully complying with field acceptance criteria.
❌Extended discharge validation requires continuous operation, yet inadequate protection raises risks of thermal runaway and equipment damage.
✅Integrated multi-layer protection including overtemperature, overcurrent, undervoltage cutoff and emergency halt enables reliable unattended long-duration discharge validation.
❌Project handover and third-party audits require traceable test records, capacity curves and formal test documentation.
✅Optional high-precision data acquisition module logs real-time voltage, current and cumulative capacity; test data and curves can be exported via USB for official reports.
❌Fixed loading modes cannot match variable rated parameters of different battery modules, UPS and DC power assets.
✅Stepwise load switching design allows segmented adjustment of discharge current to adapt to diverse test objects and validation requirements.
❌High-power continuous testing often suffers from insufficient heat dissipation, leading to derating and unstable test results.
✅Optimized forced-air cooling system sustains full-load continuous operation, avoiding power derating and guaranteeing repeatable, consistent test data.
