In modern data centers and power systems, a stable and reliable power supply is crucial. Before a system is officially put into operation, engineers must conduct comprehensive load testing using specialized equipment.
RATA 125kW 600Vac Resistive Load Bank (RTLB125L) is engineered for data center UPS, generator, and power system testing, featuring 3P4W design, ±3% total accuracy, and 1kW fine-step adjustment.
Equipped with Ni-Cr alloy resistors, 12 axial flow fans for forced cooling, and multi-protection functions, it supports local HMI & PLC remote control, Modbus TCP for data monitoring, and test report generation, with portable casters and CE/ISO certifications.
Product Introduction
This is the RATA 125kW 600Vac resistive load bank, designed specifically for data center power system testing and generator performance verification. The equipment supports three-phase four-wire systems, with a rated test voltage of 600Vac.
The load insulation resistance is above 20MΩ for DC 1000V; the insulation test voltage is 2000V AC for 1 minute; it uses an auxiliary power connection of 125V NEMA 5-15P (male socket), capable of simulating the power load in a real-world operating environment.
