Three-Phase AC Flow Control Load Box

ZJ-AC240V64A
Customized processing can be made according to requirements
Three-phase AC flow control load box It has a built-in pure resistive load , which can be adjusted from 1A to 64A in the range of 200V to 240V. It can simulate various power loads in any combination to meet the needs of full-load detection of charging piles . It is an essential detection 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 loading is performed through the host computer software.
Flexible scalability
The system has flexible scalability, which is convenient for adding more stations and power in the future and protecting the existing investment
The load boxes can be used in parallel, which is convenient and reliable to operate
High reliability and stability
The internal carrier adopts alloy resistor , which has small volume, good heat dissipation performance, strong load-bearing capacity, strong impact resistance and high stability. It can ensure the quality of the product and long-term continuous working performance.
Strong overload capacity
Load part : The load is a long-term working system, which can work continuously for 24 hours. 5 times overload, 5 seconds, the carrier has no damage
Within 30 minutes, the load is 1.2 times the load without any damage
(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 box classification:
Each phase meets 200-250V
1-64A adjustable, minimum step 1A
(3)The LCD panel can display the voltage, current and power parameters of each phase at the same time.
(4)The analog load should use 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 segmented switch. The load works in energy consumption mode, and the heat dissipation is in forced air cooling mode.
(6)The fan adopts a large axial flow fan, which has the characteristics of large air volume, good heat dissipation and low noise.
