300A DC 750 Resistive Load Bank for Charging Pile Testing System
Introduction of the resistive load bank:
It offers the most robust, high-capacity designs in the industry. It is setting the standard with intelligent operator controls, safety indication layouts, adjustable load step resolution, and lightweight designs. It is the perfect solution for regularly scheduled maintenance testing and commissioning of mission-critical standby emergency power systems.
Multifunction:
1. Control mode: (1) manual control (2) remote control (3)software control
2. Multiple display function: voltage, current, frequency, power factor, active power, reactive power, apparent power etc...
3. Multiple protection function: overvoltage, overcurrent, overheat, over low blowing rate, blower overheat, blower phase sequence reverse protection, smoke alarm etc.
4. Forced air cooling: industrial heavy duty fan,forced air cooling, horizon air intake, upwards outlet, low noise.
5. Power consumption components: made by special alloy resistance, high temperature resisting, high heat dissipation capability, high heat stability, no naked light, safety and reliability. Running temperature is 1/3 of rating.
6. Rain-proof structure: containerized structure provides ultra protection, protection grade higher than IP55.
7. Material and coating: the body adopt cold-rolled steel plate that processed by galvanizing corrosion protection, powder coated and spray paint.
8. Integrated & modularization design: compact structure, easy to installation, maintenance and transportation.
9. Software control: it can test and display voltage, current, frequency, power factor, active power, reactive power, apparent power etc, the test result can be store & print and form all kinds of curve, chart and test report.
