Description
The ABB DSSR170 48990001-PC is a Voltage Regulator Unit from the ABB Advant OCS series, primarily used to convert an unstable 24V DC input into a controlled 5V DC output to power critical control system components.
Applications
Paper mills: Used for logic power supply in paper machine drives and DCS control systems.
Steel/Smelting plants: Provide stable voltage for low-voltage electronics in blast furnace controllers at high temperatures.
Power systems: Core power supply for substation automation and Advant Controller 450 series controllers.
Petrochemical/Chemical plants: Used for energy flow control in industrial frequency converters such as the ACS800 series.
Troubleshooting
Common Faults:
FAIL light on (red): May be due to input undervoltage (<16V) or failure of the module's internal voltage regulator circuit.
No output: Check if the mounting screw on top of the module is tightened; this screw also functions as a start switch.
Solutions: Undervoltage lockout reset: Ensure the input voltage returns to the normal 24V range, then re-insert the module or restart it using the screw switch.
Spare part replacement: When replacing, ensure the new module is inserted into the exact same position as the old module.
FAQ
Q: What are the output specifications of the DSSR170 48990001-PC?
A: The DSSR170 48990001-PC steps down and regulates 24V DC to 5V DC, with a maximum output current of 10A.
Q: What is the normal state of the indicator lights on the DSSR170 48990001-PC module?
A: During normal operation, the green LED (IVE) on the DSSR170 48990001-PC is lit. If the red LED (FAIL) is illuminated, it indicates a module fault or undervoltage condition.
Q: Are there any special physical restrictions when installing the DSSR170 48990001-PC?
A: Yes. The mounting screws on top of the DSSR170 48990001-PC have a switch function. They must be properly tightened to activate the module.
Q: Can the DSSR170 48990001-PC be replaced while the system is powered on?
A: Yes. In systems with (n+1) redundancy, the DSSR170 48990001-PC supports online hot-swapping without affecting normal system operation.
Q: Will large fluctuations in input voltage affect the DSSR170 48990001-PC?
A: The DSSR170 48990001-PC includes a built-in "WATCH" monitoring system. If the input voltage drops below 16V, it will trigger protection and block the output.
