Portable DC690V-108KW AC Resistive Load Bank For Generator Testing/ UPS testing
Portable DC690V-108KW AC Resistive Load Bank For Generator Testing/ UPS testing
1. Introduction:
VILVA-DR DC pure resistance load bank adopts segmented combination control for power input, unified segmented power input, and supports sudden addition/unloading. The load adopts energy-consuming working mode and forced air-cooling heat dissipation, which greatly ensures constant The reliability of power discharge, new power consumption components are produced with independent intellectual property rights, have high power density and no red hot phenomenon.
The automatic overheating protection function prevents overheating and burnout in the unexpected event that the fan does not rotate. It is safe and has a long life.
The whole machine adopts a modular design, which is simple to operate and maintain. It can measure voltage, current and other parameters according to customer requirements. It provides a scientific detection method for high-power DC power equipment and meets the requirements of charging pile module testing, inverter battery discharge testing, and power supply testing. Testing, battery testing, solar panel testing, electric vehicle charger testing and other application fields, it is an essential testing tool for production workshops, laboratories, installation and debugging, and scientific research and development.
The fan adopts a small axial flow fan, which has the characteristics of large air volume, good heat dissipation and low noise;
It has automatic alarm protection function for temperature overheating: when overheating occurs due to special reasons, theload can be automatically cut off to ensure safe use;
The fan starts automatically when the load is loaded and stops automatically after the load is unloaded;
Independently developed new power consumption alloy resistor, with high power density, no red heat phenomenon and long service life;
Communication interface: Ethernet, (reserved 485 interface, following modbus-RTU: for users to develop their own software);
The software can set the power value to be loaded, automatically calculate and load the required power level, conduct ON/OFF stress testing, and conduct real-time data recording and fault inquiry;
Control mode: Local touch screen & Remote control host computer software (can be controlled via PC & mobile APP).
