Optical signalization MPS-1
used for optical signaling of the voltage
OPTICAL SIGNALIZATION FOR 3-PHASE NETWORK
Circuit monitoring: used for optical signaling of the voltage
Monitored ranges: level in three phases
Power supply: AC 3x400/230V, 50/60Hz
Each phase has LED signaling
broken down by color into voltage levels:
- voltage in tolerance of +/-15%
- green
- overvoltage - red
- undervoltage - yellow
- voltage < 50V - LED not illuminated
