TDS-90kw 400v resistive AC load bank Manufacturer Rata
Product Introduction
Designed with a 400Vac rated testing voltage and 1kW load step resolution, the RTLBS90L offers granular control over load testing scenarios, while its continuous duty cycle and robust construction (cold rolled stainless steel enclosure, IP54 control chamber) ensure seamless operation in harsh ambient conditions ranging from -20°C to +50°C and at altitudes up to 2000m.a.s.l.
Equipped with advanced Siemens PLC control, patented Nexus-1 software, and support for Mod Bus TCP/RS485 remote communication, it enables automated, real-time testing with data logging and reporting capabilities—streamlining testing workflows for power system manufacturers, maintenance firms, and industrial facilities worldwide. Certified to ISO9001, ISO14001, ISO45001, and CE, this load bank combines cutting-edge technology with eco-friendly design, meeting the stringent ESG and quality requirements of the global electrical testing market.
