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.Special electrical units equipped with an emergency battery pack for 1 or 3 hours (EL1/EL3) are available. These units must be used with 7-wire light-line sections.
