Overview

Ws-50ma / 300V programmable resistance box

Product Details

Product overview:

Ws-50ma / 300V program-controlled resistance box is applicable to the leakage current test of charging pile. It has "constant current" load mode and provides automatic compensation function, so that the equipment accuracy is much higher than that of conventional resistive load box. It is more convenient and convenient to use. Multiple system protection is configured to ensure the reliability of the equipment. The system expands one RS485 remote communication interface and uses Modbus RTU protocol, The system is the best choice for integration testing.

Product features:

1. Voltage wide range input

2. The leakage current is adjustable

3. 1mA minimum adjustment accuracy

4. Complete protection functions: overvoltage, overheating, overcurrent, over-power, module fault protection.

5. Constant resistance, constant current and conversion of two working modes to meet more test requirements

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

Application fields:

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