1、 Product Overview

The SND101 switch status indicator is a multifunctional, intelligent analog dynamic indicator. Used for 3-35kV indoor switchgear, suitable for various types of switchgear such as central cabinets, handcart cabinets, fixed cabinets, and ring main units. It can replace the existing primary circuit simulation, live display, automatic heating and dehumidification controller, and has multiple functions such as circuit breaker opening and closing status indication, energy storage indication, grounding switch indication, handcart position indication, and RS485 communication interface. This product adopts high-performance microcontroller control, industrial grade electronic components, and unique software and hardware anti-interference technology. Compared with traditional switch state indicators, it has higher reliability and stronger anti-interference ability. Tailored products: Design different functional combinations according to different user requirements.

This product has an exquisite and beautiful appearance, greatly simplifying and beautifying the panel of the switchgear.
