Safety Parameters Ui=45V Ii=2A Pi=1.2W (max ambient temp. = 60ºC) Pi=1.3W (max ambient temp. = 40ºC) Ci=Li = 0The device can be powered from an EEx ia IIC certified interface with output parameters lower than those shown above. Mounting Aspecial anti-vibration absorber built into the lower portion of the moulding effectively reduces vibration to the LED Lamps. The unit can be pole or direct basemounting. Configuration It is easy to change the order of the colours. Lenses simply unscrew and LED Lamps can be installed in any position.

Technical Specification

Tiers Can be stacked up to five tiers high using five different colours in any order. Colours Each tier available in five super-bright colours. Colours are red, amber, green, blue and white. High Reliability Use in Hazardous Areas All tiers illuminated with high reliability LED lamps designed to provide a minimum of 100,000 hours service life. Low Current Consumption All LED Lamps operate at 20mA or less and feature integral current limiting to maintain consistent brightness over the operating range of the voltage supply. In hazardous areas the light tower LED lamps must be powered through suitable intrinsically safe isolators or barriers. Up to two LED lamps and thereforetwo tiers can be driven from a single IIC interface.
