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.
Circuit monitoring: 3-phase
Adjustable range: fixed levels, indicated by coloured LED: yellow: 50-207 V, green: 207-265 V, red: 265-276 V
Power supply: AC 3x400/230 V (50/60 Hz)
Dimensions: 90 x 17.6 x 64 mm (3.5˝ x 0.7˝ x 2.5˝)
