Power Supply Combo (IPS910)
NOTE: The Power Supply Combo includes a 3 A Switch Mode Power Supply which
provides power for the (optional) internal unit and for charging the (optional)
backup Battery. As the Power Supply Combo needs no more than 1 A, you
may power extra devices using up to 2 A continuous current from the
provided connector block. DO NOT exceed this 2 A limit on continuous
current draw. Devices with a high in-rush current demand, such as certain
maglocks and other electromechanical devices, can momentarily draw more
than 3 A. The Power Supply then effectively shuts down as directed by its
built in protection as exceeding the 3 A rating is considered a short-circuit.
Overcome this by installing the recommended 12 V 7 Ahr Battery to help
supplement the in-rush current such a device may draw on activation.
