• DC power supply (10.5-16V) - provided by default with the ACE3600 RTU
• DC power supply (18-72V)
• DC power supply (18-72V) with battery charger
• AC power supply- 85-264V
• AC power supply- 85-264V with battery charger
Common characteristics of all power supply modules:
• On/Off switch on the front panel
• Controlled auxiliary voltage outputs
• Heat convection cooling (no need for fans)
• Short protection outputs
• Over heating protection
• The module function is monitored by the CPU module.
• Status LEDs in the front panel
• PS located on the leftmost slot of the frame
• Input current protection fuse
• Controlled power line enables centralized disabling of Electrically Energized relay outputs
in selectable DO modules.
Common characteristics of power supply modules with battery charger:
• Automatic switchover to battery on power fail
• Automatic switchover to main power on power return
• Temperature compensated charging
• Over-charging protection
