Three-phase AC load box
It has a built-in pure resistive load, which is adjustable from 0.1KW to 20KW and can simulate various power loads in any combination to meet the needs of full load detection of generators. It is an essential test tool for production workshops, laboratories, installation and commissioning, and scientific research and development.
Application scenarios: It is widely used in inverter production, scientific research and development, testing and identification institutions, electrical laboratories of universities, product acceptance and daily maintenance and testing.
Key Features
1、The control modes are local touch screen control and remote computer control, and the two modes are interlocked.
2、PLC model XL5E, power loading is performed through the host computer software.
3、Flexible scalability
- The system has flexible scalability, which is convenient for future increase of stations and power,and protects the existing investment.
- The load boxes can be connected in parallel, which is convenient and reliable to operate.
4、Highly reliable stability
- The internal carrier adopts alloy resistor, which has a small size, good heat dissipation performance, strong load-bearing capacity, strong impact resistance and high stability. It can ensure the quality and long-term continuous working performance of the product.
5、Powerful overload capacity
- Load part: The load is a long-term working system that can work continuously for 24 hours.
- 5 times overload, 5 seconds, no damage to the carrier.
- Within 30 minutes, 1.2 times overload,no damage to the carrier.
