HDR-60 48V DIN-Rail Power Supply for Akuvox 2-Wire Intercoms (HDR-60-SPEC)

An Akuvox two-wire intercom runs on 48V DC, and the devices are sold without a supply. The HDR-60 is the unit we use for it: a slim DIN-rail power supply from Mean Well's HDR-60 series that clips onto a TS-35 rail in the intercom cabinet and takes the mains feed.

In a building, it powers the Akuvox NS-2 2-wire switch, which then passes power down each pair to the door phones and monitors. In a villa without an NS-2, it powers the C313W-2 two-wire monitor directly, and the monitor feeds the door phone (R20A-2 or E12S-2) over the two wires; that is how our Akuvox two-wire kit is built.

It delivers up to 60 W (48 V at 1.25 A) from a universal 85–264 V AC input, so it runs from Kuwait's 240 V supply directly. Mount it in a ventilated cabinet, and have the mains side connected by a qualified electrician.
