High precision switch status indicator

JOE300T High precision switch status indicator  A high-precision switch status indicator is an indicator used to display the status of a switch. It usually consists of a small LED light and a transparent lampshade. When the transfer switch is on, the indicator lights up to remind the user of the current status of the protection transfer switch. When the switch is off, the indicator light will go out. The high-precision switch status indicator has the following functions: 1.high-voltage live display part of the LED lighting voltage (KV) : rated phase voltage ×0.15-0.65; Lock control voltage (KV) : rated phase voltage ×0.65; When the live display is in a state of no power, the lock can be lifted. After release, the lock release green indicator lights up.  2. temperature and humidity simulation control function can be with 1-2 way temperature and humidity control; When the ambient humidity is ≥90%RH, start heating. When the humidity is less than or equal to 75%RH, remove f…
