Product Description
I. Overview
The three-phase AC programmable load bank has a built-in pure resistive load that meets the 1A-64A adjustable range within 200V~240V. It can be arbitrarily combined to simulate various power loads to meet the full load detection requirements of charging piles. It is a necessary testing tool for production workshops, laboratories, installation and commissioning, and scientific research and development.
Function introduction
- The control mode is local + remote control.
- PLC control, power is loaded through the host computer software.
Flexible scalability
- The system has flexible scalability, which is convenient for future station and power increases, protecting existing investments.
- The load banks can be used in parallel, which is convenient and reliable.
Highly reliable stability
- The internal carrier adopts alloy resistance, which has small size, good heat dissipation performance, strong bearing capacity, strong impact resistance and high stability. It can guarantee the quality of products and long-term continuous working performance.
Powerful overload capacity
- Load part: The load is for long-time work system and can work continuously for 24 hours. 5 times overload, 5 seconds, the carrier is not damaged.
Within 30 minutes, the load is 1.2 times the load without any damage.
II. Main technical parameters
(1) According to the performance parameter detection requirements, the corresponding power can be controlled and set, and the discharge power can be arbitrarily combined and set.
(2) Load bank grading:
| Each phase meets within 200-250V 1-64A adjustable, minimum step 1A. |
(3) The LCD panel can display voltage, current and power parameters of each phase at the same time.
(4) The analog load should select low temperature drift (temperature coefficient <250ppm), high reliability and accuracy components, and the loading accuracy should meet the relevant requirements of HB6492;
(5) The power input is controlled by a segmented switch. The load works in an energy-consuming manner, and the heat dissipation is forced air cooling.
(6) The fan adopts a large axial flow fan, which has the characteristics of large air volume, good heat dissipation and low noise.
