PS6R expandable power supplies in 120-, 240- and 480-W models achieve up to 93% efficiency and have expansion modules, including dc-dc converters that let three separate voltages be used simultaneously. A branch terminal module provides additional wiring terminals. A low-voltage alarm output with NPN contact and LED indication is available. Each model is UL- and TUV-approved, CE-marked, and complies with EMC and LVD directives.
