Optical signalization MPS-1

• Used for optical signaling of the voltage level in three 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.
• Four-wire connection – L1, L2, L3, N.
• Monitors phase voltages against neutral wire.
• Not dependent upon order of phases.
• Four-wire connection – L1, L2, L3, N.
• In 1-MODULE design, DIN rail mounting
