PW702 YOKOGAWA Dc power module

The DC power module is an independent module that converts AC power into DC power. It is usually composed of a high-frequency switching power module, a control unit, a measurement module, a switching module, an insulation detection module, a battery test module, and multiple AC inputs, DC voltage display, and current display.

The DC power module provides various protection functions, such as input overvoltage protection, output overvoltage protection, output current limit protection, and output short circuit protection. When the input AC voltage is less than 80±5V or greater than 270±5V, and the DC voltage is less than 34±1V or greater than 60±1V, the module is protected without DC output, and the protection indicator (yellow) is on. In addition, if the output DC voltage is greater than 60V, the module is protected and has no DC output. However, the module cannot be automatically recovered in this case. You must power off the module and power it on again.

In addition to the protection function, the DC power module also has the short-circuit retraction function. When the module output is short-circuited, the module will automatically resume normal output after the short-circuit factor is removed. After the abnormal conditions are cleared and the internal temperature of the module returns to normal, the module automatically returns to normal operation. At the same time, the module alarm information is displayed in the form of a fault code on the LED flashing in real time.
