Used for optical signaling of the voltage level in 3-phases.
Each phase features LED signaling broken is divided by color into voltage levels:
- voltage in tolerance of ± 15 % - green
- overvoltage - red
- undervoltage - yellow
- voltage < 50 V - LED not illuminated.
4-wire connection - L1, L2, L3, N.
Monitors phase voltages against neutral wire.
Not dependent upon order of phases.
