LLM3 Live line monitor

LLM3 live line monitor is used to indicate the presence of voltage in the three-phase power supply.

Each of the monitored phases is indicated by a LED display with an appropriate marking. E.g. L1, L2, L3. The red LEDs of the relevant indicator go out when the phase fails.

An additional external LLI3 phase presence indicator provides a convenient view of the power network status at the control cabinet door.

 

Description

Lumel LLM3 live line monitor is used to indicate the presence of voltage in the three-phase power supply.
Each of the monitored phases is indicated by a LED display with an appropriate marking. E.g. L1, L2, L3. The red LEDs of the relevant indicator go out when the phase fails.
An additional external LLI3 phase presence indicator provides a convenient view of the power network status at the control cabinet door.

The LLM3 Live line monitor is a device intended for signalling voltage presence in a three-phase network with a neutral wire. Each of the monitored phases corresponds to a set of couble signal diode with the appropriate marking – according tot he ordering code (e.g. L1-L2-L3). For applications in low voltage networks, intended for automation and control systems.

Advantages of LLM3 + LLI3 set:

Safety: LLI3 indicator operates with low voltage potential due to full galvanic isolation from the power network
Reliability: Each phase is signalled by two independant LEDs and the analogue design provides resistance to electromagnetic interference.
Versatility: Signalling available inside the control cabinet (LLM3 monitor) and on the board (LLI3 indicator)
Convenience: Red LEDs for clear visibility in all conditions
