Product catalog summary

Overview: The LN870 Intrinsically Safe Light Tower is designed for status indication in both safe and hazardous areas. It can be configured with up to five tiers, each available in five super-bright colors: red, amber, white, blue, and green. The light tower is suitable for use in hazardous zones 1 and 2 and is ATEX certified.

Specifications:

Colors and Configuration: Each tier can be stacked in any order and is available in five colors. The configuration is flexible, allowing easy changes by unscrewing lenses and repositioning LED lamps.
LED Lamps: High reliability with a service life of at least 100,000 hours. Each lamp operates at 20mA or less, with integral current limiting for consistent brightness.
Mounting Options: The unit can be mounted directly or on a pole, both featuring a vibration absorber to protect the LED lamps.
Certification: ATEX certified to EN50014:1997 and EN50020:2002, suitable for Group II, Category 2G, EEx ia IIC T4 environments.
Safety Parameters: Ui = 45V, Ii = 2A, Pi = 1.2W (max ambient temp. = 60ºC), Pi = 1.3W (max ambient temp. = 40ºC).
Environmental Conditions: Operating temperature ranges from –20ºC to 60ºC, with storage temperature from –20ºC to 80ºC. Humidity tolerance is 0-95% RH, non-condensing.
Protection and Compliance: IP40 protection with an IP54 option available. Complies with immunity and emissions standards EN61000-6-2:2001 and EN61000-6-4:2001.
