Ws-6600 series - DC electronic load

‍

Product Description:

Ws-6600 series - DC electronic load is applied to daily maintenance test, engineering acceptance and delivery inspection test of DC charging pile. The detection of output power and load capacity of various DC charging pile equipment has not been carried out effectively and smoothly. It is only after the power supply failure that it is known that the DC charging pile can have a problem. Our equipment can accurately measure the output power and load capacity of the charging pile.

Function introduction:

1. During the project acceptance of newly installed DC charging pile equipment, check whether the output power of DC charging pile equipment and battery can meet the design requirements.

2. Daily maintenance and routine inspection of DC charging pile equipment.

4. The test data of important parameters such as power, voltage and current are clear at a glance.

5. All high efficiency electric heating elements comply with UL safety specifications.

6. It has fan fault detection, overvoltage, overcurrent, leakage and other protection functions.

7. Programmable support RS485 communication interface, Modbus RTU standard communication protocol.

8. Multiple parts can be discharged in parallel to adapt to the occasion of high current discharge.

Application fields:

Test the output power and load capacity of DC charging pile.

Power consumption element

It is packaged with salt spray resistant and acid-base resistant stainless steel pipe and heat sink. The resistance material has the performance characteristics of low impedance, high precision and low temperature drift

The overall seismic resistance and oxidation resistance are better than traditional load elements, and meet the long-term continuous work.

Loading accuracy

≤1%F.S.

Automatic compensation

Under the constant power or constant current mode, if the error range of the set value is exceeded, the system will automatically compensate to realize the high-precision regulation of the load
