Product Details

ABB DSSR122 is a DC-DC power supply module designed for ABB Advant OCS distributed control systems. The DC-DC power supply module converts 24V DC input power into stable 5V DC output to supply power for controller boards, I/O modules and communication cards inside the control rack. This ABB DSSR122 module features high conversion efficiency and strong load capacity, it can continuously provide stable low-voltage power for multiple circuit boards in the rack. The Advant OCS rack power unit integrates overvoltage, overcurrent and short-circuit protection functions to avoid damage to expensive control boards under abnormal power conditions. It has built-in self-diagnostic function and LED status indicators to monitor input voltage, output status and internal faults in real time and send out alarm signals for rapid maintenance. The robust metal housing and conformal coated circuit board resist dust, moisture and vibration, adapting to heavy industrial environments. Widely applied in power, metallurgy, chemical, pulp & paper and water treatment industries for Advant OCS DCS cabinet power supply backup and replacement. Rack plug-in structure enables convenient installation and quick field replacement.
