Main Functions
(1) Load Testing: The load bank can be adjusted with a minimum step of 3kW to meet loading settings from 3kW up to the rated power, for testing the AC power source output capacity.
(2) Control Method: Equipped with a local control panel divided into several power levels,controlled via switches.
(3) Data Display: Local measuring instruments display phase voltage, phase current, power, frequency, etc.
(4) Emergency Stop: Manual one-key forced unloading with emergency stop reset function.
(5) Overvoltage Protection: When input voltage exceeds the safety threshold, automatic unloading and alarm activation.
(6) Short-Circuit Protection: The load circuit is equipped with fuses; in case of short circuit, automatic unloading is triggered.(7) Overtemperature Protection: When the load temperature exceeds the safety threshold, automatic unloading and alarm activation.
(8) Fan Interlock Protection: The load cannot be applied before the fan power switch is turned on.
(9) Protection Switch: Some protection functions have dedicated switches, which can be temporarily disabled in case of false alarms or special requirements.
