New Arrival SILV-500kw Resisitive Load Bank Manufacturer Rata
Product Introduction
Engineered with a 415Vac rated testing voltage, 1kW load step resolution, and a flexible load step configuration, the SILV500-L provides ultra-precise control over load testing scenarios, while its continuous operation capability and rugged construction (2mm thick steel IP54 enclosure, 400A waterproof quick connectors) ensure uncompromising performance in extreme ambient conditions from -20°C (-4°F) to +50°C (122°F) and at altitudes up to 2000m.a.s.l.
Equipped with HMI touch screen manual control, PC software remote operation, and Modbus TCP communication, it enables automated, real-time testing with seamless data integration, optimizing workflows for power system manufacturers, maintenance teams, and industrial facilities worldwide. Boasting thermal emergency cut-out, fan overload protection, and emergency stop features, this load bank prioritizes operational safety, while its castor-mounted portability and horizontal forced air cooling (70m³/h per kW airflow) enhance usability and durability for both indoor and outdoor applications. Certified for global compliance, the SILV500-L merges cutting-edge engineering with practical design, meeting the stringent demands of the international electrical testing market and supporting sustainable power infrastructure development.
