The JS-1 TBP overvoltage action counter is a device that performs real-time and cumulative counting of the working status of TBP products. Through this product, the TBP and the equipment protected by TBP can be monitored in detail, and abnormal situations before accidents can be predicted. To achieve the effect of analyzing the causes of abnormal actions and preventing accidents from occurring.
Product structure and features:
Each JS-1 TBP overvoltage action counter is a two-part structure, connected via RJ45 interface and Ethernet cable. Different installation methods can be adopted according to on-site needs. The counter adopts STN dot matrix LCD display, high-speed data processing unit, and software digital filtering.
It has the characteristics of strong anti-interference ability, easy installation, and accurate counting. It can accurately record the number of actions between the three phases of TBP overvoltage protection in real time, and the recorded data can be accumulated by phase.
Operation and maintenance:
The TBP overvoltage action counter of the battery is designed passively and does not require an external power supply. The body comes with a battery that can be used for 3 years. If the battery is low, please contact our unit immediately for supply. The battery is located inside the data display box and can be replaced by opening the back cover. The statistical software design adopts real-time power-saving mode. When you need to observe data, please lightly touch the reading button once, and the accumulated overvoltage times between phases AB, AC, AD, BC, BD, and CD will be displayed in sequence. After the sequence is completed, the LCD display will automatically turn off.
Clear, data needs to be cleared. Press and hold the button for one second. When "ERASE" appears, a dot will appear in one second. After all three dots appear, it means that data clearing is complete. During this process, if you need to give up clearing, release the button before the third point appears, and the reset will be canceled.

Installation method of JS-1 (TBP-J) series passive discharge counter:
1. Overall installation
The display part of the TBP protector body mounted counter is directly hung on the protector.
