AC (Mains) Power Supply
AC (Mains) Power Supply Unit MGP150 is a switching power supply,
which operates from the universal AC (mains) input from 85 to
264 VAC and 50/60 Hz. The output voltage is 15 VDC, which is used
for powering the AWS system, and as an input to the Battery Regulator
for charging the back-up battery.
MGP150 is installed inside the AWS enclosure on a standard DIN- rail
enabling easy maintenance of the unit.
Some sensors, such as the heated ultrasonic wind sensor, require higher
DC voltage. In those installations, an additional mains power supply
MGP360, a 36 VDC power supply module is installed.
