Maxos TL-D IP64 electrical units – Protection plus The IP64 electrical units are designed for quick and reliable mounting in Maxos IP64 light-line sections. They are made of steel with a white powder finish. The high IP classification is possible due to special seals between the light-line sections and to lamp holders with gasketted screw rings on the IP64 electrical units. Maxos IP64 is not designed for application in regular humid environments. A connector block is mounted for electrical connection to the light line. The electrical units are equipped with electronic ballasts (including dimmable and DALI) or low-loss conventional ballasts. The conventional ballasts are available as inductive, parallel compensated (IC) or inductive (I). The units can hold 1 or 2 TL-D lamps Dimmable versions are delivered with HF-R electronic ballast, allowing the light output of the TL-D lamps to be regulated from 3 to 100%. HF-R and HF-DALI units must be mounted to 7-wire light-line sections. The electrical units can be combined with dedicated IP64 trapeze reflectors and a selection of aluminum reflectors. These aluminum reflectors offer a choice of narrow-beam, asymmetrical-beam and very-narrow-beam light distributions for 1 x 58 W. Units which comply with the FF rules (limited surface temperature) are available on request.
