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…
