High-frequency electronic ballasts for 4-pin fluorescent lamps/tubes with 20 addresses for function monitoring (CEWA GUARD Technology) and switching modes (maintained/non-maintained and switched emergency luminaires).
Making them freely programmable in one circuit without additional data line to the luminaires in conjunction with suitable emergency lighting systems (with STAR-Technology).
Eaton offers a wide range of special ballasts for emergency lighting for installation into existing light fittings. The ballasts include a monitoring module which signals the luminaire’s current status to the central emergency lighting system. This means that only one ballast must be installed into the luminaire, safe operation in the DC voltage range of 186 - 275 V is ensured, and the danger of specifying the wrong ballast is minimised.
By the use of efficient electronic ballasts with automatically reduced luminous flux in battery operation, a considerable reduction of energy is achieved. This saves costs and adds to environmental protection since it provides equal safety with smaller batteries.
With Eaton monitoring modules, electronic ballasts or LED supply modules, luminaires for general lighting systems from any manufacturer can be connected to central battery systems and thus integrated into the building emergency lighting concept.
The modules matched to the requirements of central battery systems installations make it possible to monitor and control up to 20 luminaires in only one circuit. Using the ballasts, luminaires on one circuit can be operated in different switching modes such as maintained light, non-maintained light or switched maintained light.
Here in the case of the N-EVGs (electronic ballasts), the emergency lighting level of each lamp can be individually set for battery operation from 30 to 100 % of the nominal luminous flux. Addressing and adjustment of the luminous flux are performed, as usual, via easy to access coding switches. Please observe our electronic control gear requirements for monitoring third-party luminaires.
