The Mains power supply unit MGP15V is a switching power supply,
which operates from the universal mains (AC) input of 85 to 264 VAC
and 50/60 Hz. The output voltage is 15 VDC, which is used to power
the MAWS system, and as an input to the Battery Regulator
QBR101B to charge the back-up battery.
MGP15V is installed inside the MAWS enclosure on a standard DIN-
rail enabling easy maintenance of the unit.
Some sensors, such as the heated ultrasonic wind sensor
WS425STDH, require higher DC voltage. In these installations, an
additional mains power supply MGP36V-M3, a 36 VDC power
supply module will be installed.
Power Supply
The mains power supply modules are delivered as packages that also
include surge aerators and all internal wiring in the MAWS enclosure:
• MGP15V-230-M3: for 230 VAC mains power
• MGP15V-115-M3: for 115 VAC mains power
