Ws-700k / 1000v-2t two-way programmable resistance box 產(chǎn)品信息

Two way programmable resistance box

Product overview:

Ws-700k / 1000v-2t program-controlled resistance box is applicable to the insulation resistance test of charging pile. It is more convenient to use, and the configured multiple system protection ensures the reliability of the equipment. The system expands one RS485 remote communication interface and uses Modbus RTU protocol. It is the only choice for the system integration test.

Product features:

1. Voltage wide range input.

2. Both AC and DC.

3. The resistance value is adjustable.

4. Resistance value display.

5. Two channel design.

6. The protection function is complete.

7. The two working modes of debugging mode and load mode are converted to meet more test requirements.

8. Support a variety of remote control, standard RS485, optional Ethernet communication control. Support standard Modbus communication protocol.

Application fields:

Automobile electronic test, power supply test, battery test, leakage current detection test of DC switching components.
