IMAX2925-200KW
EMAX
This load bank is used for AC power supply testing and can test AC power supply, alternator, etc. The load bank is divided into 2 groups of independent load bank, and the incoming lines of the 2 load groups are each equipped with 4 incoming workstations for selection and switching (a total of 8 incoming workstations).
1. Can meet long-term outdoor use;
2. Provide the upper computer operating software
3. RS485, Ethernet, CAN and other communication ports
4. The test steps are programmable, suitable for diesel generator set, gas generator set, anti-reverse power transmission, automatic test
5. Can load any power within the full power range, any power factor, test and display three-phase voltage, current, power, power factor;
6 Power adjustment accuracy: 1kW
7. Use PC data management software to control load loading and load unloading and save test data
