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