    Emergency Power Pack EP-HS Series 2

    The EP-HS2 emergency power pack with transfer relay is compactly designed, perfect for hidden installations in the ceiling to provide power for emergency lights installed in or under the ceiling. The EP-HS2 power pack is special in that it can supply either a 12 Vdc or 220 Vac power supply. A switch to turn on or off the power pack can be installed at any desired location and it is also equipped with the innovative 3 Steps Charger (patent number 15955) to help extend the operational life of the battery. The casing is produced from 1mm thick Electro-Galvanized steel coated with Epoxy powder and special chemicals to prevent any possible rust. The EP-HS2 emergency power pack with transfer relay has undergone continued innovation to give maximum value and functions to the users, as can be seen in the feature list.
