Product Advantage
1. User can press the emergency stop button in the panel to unload
immediately when the load bank is abnormal while working.
2. Over-load: Automatic load dump and give alarm when voltage is
over safety thresholds.
3. Short Circuit Protection: Fuse could avoids damage to equipment
when short circuit or current overload.
4. Fan protection: Machine could not do load testing before working
power of fan is on.
5. The machine will unload and give alarm when any fan is abnormal
or with insufficient air volume, etc.
Application
About resistor alloy, we use nickel-chromium alloy(NiCr6023) which
can withstand high temperature (Max operation temperature at
1,300℃), be of small temperature drift (5*10-5/℃) and steady
electrical performance.
