Technical Specifications Wide AC/DC input range, 24VDC regulated output. Operating temperature: -40℃ ~ +70℃, built-in overvoltage, overcurrent and short-circuit protection.
Functional Features Voltage regulation conversion, ripple filtering, power fault alarm, transient surge suppression.
Application Scenarios Power supply for 9904 series control rack, I/O modules and matched signal accessories.
Performance Parameters Low output ripple, high conversion efficiency, fast protection response.
Structural Characteristics Rack pluggable power module, power normal and fault LED indicators.
Working Principle Unstable input power is converted to constant 24VDC output by internal power circuit. When electrical abnormalities occur, the module automatically cuts off the output for protection.
Installation Requirements Install in the dedicated power slot of the 9904 rack, reserve enough ventilation space for heat dissipation.
Usage Notes Verify input voltage before powering on, replace the module immediately if the fault alarm is triggered.
