3.8 Redundant Power

The UPC-V312-D525 is a system that supports redundant power. The redundant power

input increases the reliability of the system while preventing data loss and system

corruption from sudden power failure. The system can instantly and uninterruptedly switch

to the second power input when the main power is unavailable or in low voltage capacity.

There are two power connectors on the bottom panel. Power 1 connector is a 3-pin

terminal block that supports ACC On signal. Power 2 connector is a DIN connector that

can directly connect to a power adapter. The supported power input voltages are:

 Power 1 (Terminal block): 9 V (+/-3 V) ~ 36 V

 Power 2 (DC jack): 10.5 V (+/-0.3 V) ~ 36 V

Figure 3-34: Power Connectors

When the system is in ACC On mode, the main power input is from the Power 1 connector.

When the system is in ACC Off mode, the main power input is from the Power 2 connector.

The ACC on/off mode is selected by the ACC on/off switch on the bottom panel.

(

Figure 3-20).

The following sections describe how redundant power works in ACC On mode and ACC

Off mode.
