AC Variable Resistive 400v 1500kw Resistive Load Bank For Testing Generators UPS
Product Description
1. Load testing: load power that not beyond the rated power, testing and display stable state 3 phases voltage, current, active power, frequency, working time, etc of generator sets.
2. Load/unload with one key:Either by manual control or software control, user can preset the power, then press load master button. Load bank loaded according to preset power to avoid load fluctuation during the power changing.
3. Control Pattern: user can choose local control and intelligent control.
4. Local Control: There is local control panel with several power steps; user can load/unload by button.

Product Advantage
Communication type: through RS232, RS485
Load mode: manual load or automatic load.
Manual load: input power and power factor.
Automatic load: User can set several periods of power and time, and in turn of 0%→25%→50%→75%→100%, etc preset order to make automatic load testing.
Application
UPS inspection and maintenance
Ship battery charging/discharging system testing
The acceptance of new system and testing of servicing equipment
Generators installed in the field must be periodically tested and exercised to ensure that it will operate as intended when a power outage actually occurs. Service groups use load banks to apply a load that mimics the load of the facility the generator is protecting. Any problems with the generator can then be identified and rectified in a non-critical environment.
