2800kW 3500kvA resistive-inductive load bank For UPS or Generator Testing
Product Introduction
Rata's RTX2400L is a high-performance 2800kW/3500kVA integrated resistive-inductive load cell designed for comprehensive testing of generators, UPS, switchgear, and other power systems.
This device has a rated test voltage of 415Vac (400V compatible), supports 50/60Hz frequencies, uses a three-phase three-wire connection, and features an adjustable power factor of 0.8-1.0. It is equipped with comprehensive safety protection: integrating multiple safety mechanisms to ensure safe and reliable testing, and features a high-efficiency cooling system.
Control Board and Connections for ref
(It varies a little according to customer's real demands)
● Low air volume: when the air volume of any fan is insufficient, it will automatically unload and alarm.
● High temperature: automatically unload and alarm when the load temperature exceeds the safety threshold.
● Emergency stop: manual one button forced unloading is available, and it cannot be loaded under emergency stop locking status.
● Fan phase sequence automatic transfer protection: when the control power line is not connected according to the correct phase sequence, the three-phase fan can also operate in the normal direction.
● Operational indicator: indicates whether the device can be put into load, and the indicator light on indicates that the device is in normal state and can be put into load.
● Fan interlock protection: the load cannot be loaded before the fan power switch is turned on.
● Fan operation indicator: indicates whether the fan of the device is running, and the corresponding indicator light for fan startup is on.
● Load switch: the control device is to switch on or off the load, and jog the switch to switch on the selected load.
