Jh-300 switch status indicator
Function description
Jh-300 switch state indicator is a multifunctional and intelligent analog dynamic indicator. It is used for 3-35kv indoor switchgear, and is suitable for various switchgear such as central cabinet, handcart cabinet, fixed cabinet, ring main cabinet, etc. It can replace the existing primary circuit simulation, live display, automatic heating and dehumidification controller, and has many functions, such as breaker opening and closing status indication, energy storage indication, grounding switch indication, handcart position indication, RS485 communication interface and so on. This product is controlled by single chip microcomputer with excellent performance, industrial electronic components and unique software and hardware anti-interference technology. Compared with the traditional switch state indicator, it has higher reliability and stronger interference ability. Tailor made products: different functional combination designs are carried out according to different requirements of users.
The appearance of this product is exquisite and beautiful, which greatly simplifies and beautifies the panel of the switchgear.
