ms2000-24

MS2000/12 and MS2000/24 are two types of mains power supplies which primarily serve for feeding all MORSE
system components. Both types provide back-up of the output DC voltage from the connected battery.

Mains power supplies work as self-acting isolation transformers (SELV) with two levels of output voltage. The lower level serves for supplying connected equipment, the higher level is designed for charging the back-up battery.

The design has been electrically and mechanically (metal case) adapted so that the power supplies can be use in demanding industrial applications. In conjunction with the battery MS2000 works as a UPS (Uninterruptible Power Supply).

Typical areas of use

  • For supplying MORSE system components: all types of radio modems, GPRS modem and other accessories
  • For supplying control systems in common switchboards with radio modems
  • For separately supplying any equipment for 13.8 V, or 24 V DC with a consumption of up to 5 A, or 3.5 A

Benefits

  • Microprocessor controlled
  • Optimisation of charging and back-up
  • Prevents completely discharging the battery by disconnecting it in time
  • Spares the life of the battery
  • Outputs (open collectors) for indicating:
    • Operation on back-up battery
    • Drop in back-up battery voltage below 11.5 V
  • Protection of primary and secondary side against short-circuiting and over-voltage when supplied from the mains or battery
  • Assembly on a DIN rail or using 2 × M3 screws
