MPA2C3 Installation Guide
An MPA2C3 panel powered by PoE+ is 802.3at compliant, providing a maximum
of PSE 30W of input power and maximum of 25.5 W of output power to the panel.
This input power is split between on-board power consumption and external
load consumption. A maximum current capacity of 1600 mA @ 12±2 VDC is
available for all external devices combined.
