Reliable Power
The Protege Intelligent 5 Amp Power Supply is capable of supplying power to a large number of smaller devices
or multiple high current devices up to a maximum of 5 Amps.
A continuous source of power is maintained with the inclusion of intelligent battery backup charging, optimal
level maintenance and seamless switch on AC failure. The battery backup and AC status are constantly
monitored, and failure conditions are communicated to the Protege System and simultaneously output to open
collector drivers suited to connection to third party warning systems.
