LLM3, 3-Phase Live Line Indicator for DIN Rail Mounting
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 double signal diode with the marking L1-L2-L3.
The red LEDs of the relevant indicator go out when the phase fails.
For applications in low voltage networks, intended for automation and control systems.
An optional external LLI3 phase presence indicator provides a convenient view of the power network status at the control cabinet door (
please select when ordering!).
Advantages of the LLM3 + LLI3 set:
Safety - LLI3 indicator operates with low voltage potential due to full galvanic isolation from the power network
Reliability - each phase is signaled by two independent LEDs and the analogue design provides resistance to electromagnetic interference
Versatility - signaling available inside the control cabinet (LLM3 monitor) and on the board (LLI3 indicator)
Convenience - red LEDs for clear visibility in all conditions
