• Total output power to all devices connected to MPA1C1 is
limited to 700mA @ 12VDC nominal, combined over the two
power outputs.
• Maximum output current for reader(s) is 500mA connected to
OSDP READER: +12V OUT & GND
• Maximum output current for the door lock output is 500mA
connected to DR LCK: +12V OUT & SWITCHED GND.
PoE Power Limitations
If you are using the MPA1C1, powering the panel with PoE, you
must comply with these specifications for proper operation:
• An MPA1C1 panel powered by PoE is 802.3af Power Class 3
compliant, providing a maximum of PSE 15.4W of input power and
maximum of 12.95W 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 700mA @ 12VDC is
available for all external devices combined.
Note:
• If connected to a PoE+ or higher Power Sourcing Equipment (PSE) the
MPA1C1 will successfully negotiate Class 3 power, so the MPA1C1
can be plugged into any PSE device, but will only draw up to Class 3
power.
• Two readers per door can still be supported as long as the total current
is within the external load capacity stated above.
• To find the power consumption of the device, refer the product
documentation or use a current meter.
• In case the MPA1C1 is powered by the PoE AND by an external power
supply on (PWR) +12V IN, then the power will be taken from the
external power supply if that voltage is over 12.2V. In this case POE
acts as a backup voltage with above limitations.
