This VILVA 1300A DC resistive load bank is built for high-current discharge and capacity verification of energy storage packs, battery strings and DC power systems. With pure resistive elements, it provides harmonic-free stable loading, step current adjustment and built-in safety interlocks. Optional data logging supports curve export for acceptance documents, ideal for factory testing, on-site commissioning and regular battery maintenance.
Pain Points & Solutions
❌Pain point: Active electronic loads introduce harmonic distortion and non-linear loading, failing to simulate the purely resistive load conditions required for official acceptance tests.
✅ Solution: Pure resistive load topology ensures linear, harmonic-free loading, complying with standard acceptance and commissioning specifications.
❌Pain point: Conventional test loads are limited in current capacity and unable to satisfy high-current capacity validation for large-format energy storage battery packs.
✅ Solution: Rated for 1300A continuous discharge current, with stepped load banks to flexibly configure target discharge current for heavy-duty capacity testing.
❌Pain point: Extended unattended discharge tests expose equipment and DUT to thermal runaway, overcurrent and under-voltage hazards without reliable protective interlock.
✅ Solution: Multi-layer safety interlock system monitors temperature, current and voltage in real time; automatically cuts off load upon threshold violation.
❌Pain point: Manual logging of discharge data yields discontinuous records, lacking auditable traceability required for project handover and certification documentation.
✅ Solution: Optional high-resolution data acquisition module continuously captures test metrics and exports discharge profiles via USB for formal test reports.
❌Pain point: Field commissioning frequently requires relocation of test gear; bulky equipment with ambiguous wiring prolongs setup time and raises connection risks.
✅ Solution: Integrated cabinet construction with clearly labelled power terminals, enabling fast wiring, secure connection and convenient on-site mobilization.
