POWER SUPPLY MODULE AND BACKUP BATTERY
General Description/Module Overview
The ACE3600 power supply module provides the other modules in the RTU with their
operating voltages via the motherboard bus.
The following power supply options are available:
• DC power supply low-tier (10.8-16V)
• DC power supply (10.8-16V) - provided by default with the ACE3600 RTU
• DC power supply (18-72V)
• DC power supply (18-72V) with battery charger
• AC power supply- 100-240V
• AC power supply- 100-240V with battery charger
Common characteristics of all power supply modules (not including the DC power supply low-
tier):
• On/Off button on the front panel
• Controlled auxiliary voltage outputs
• Heat convection cooling (no need for fans)
• Short protection outputs
• Over heating protection
• Status LEDs in the front panel
• Power supply located on the leftmost slot of the frame, to the left of the CPU.
In a frame with both redundant CPUs and redundant power supplies, the third slot from the
left (between the primary CPU and the secondary CPU) is used by the redundant power
supply.
• Input current protection fuse
• Controlled power line enables centralized disabling of Electrically Energized relay outputs
in selectable DO modules.
Note: The DC power supply low-tier does not support radios that require input power other
than 10.8-16V. Do not use portable radios which require 7.5V input with this option.
