Power supply indicator lamp 3xLED red, yellow, green, slim 1/3 module LK-703K

Power supply control in a compact edition

The LK-703K power indicator lamp is a reliable signaling device designed for optical control of voltage presence in 3-phase networks. Its exceptionally slim housing, occupying only 1/3 of a module on a DIN rail, allows for saving space in switchboards and control cabinets. This is an ideal solution for both professional installers and end users who value order and functionality.

Functionality and application

The device is equipped with three LEDs – red, yellow and green – which indicate the presence of voltage in each phase. This allows for quick and precise identification of any power supply problems. The LK-703K lamp finds application in:

• electrical switchboards,
• control cabinets,
• industrial installations,
• commercial and residential buildings.

Mounting on a standard 35 mm rail is simple and intuitive, and the connection using 2.5 mm² screw terminals ensures a safe and stable connection. Low energy consumption (0.15 W/channel) translates into savings in the long run.

Construction features and operating parameters

The LK-703K lamp has been designed with durability and reliability in mind. Operation in a wide temperature range (-30°C to +50°C) guarantees trouble-free operation even in difficult environmental conditions. The IP20 degree of protection provides basic protection against touch and contamination. The device is adapted to work with various supply voltages: 3x24 V+N, 3x110 V+N and 3x230 V+N. The rated current per channel is 1 mA. The tightening torque of the terminals is 0.4 Nm, which ensures a secure connection of the wires.
