How to install SDR-480-24

  • Power down the control panel and verify there is no supply voltage present before wiring the unit.
  • Mount the SDR-480-24 on a standard DIN rail (TS-35) inside the enclosure, ensuring it sits securely and remains free of obstructions.
  • Connect the input wiring to the L and N terminals on the power supply, observing correct polarity and tightening screws to a secure connection. Connect Protective Earth (PE) if provided or required by local code.
  • Attach the output load to the 24 V DC (+V) and 0 V (-V) terminals, keeping wiring neat and within current ratings to avoid overheating.
  • Power up the cabinet and verify the Power-on LED illuminates. Check the DC OK relay contact status and ensure it is signaling proper output health to your controller or alarm system.
  • Test critical loads with a controlled inrush scenario to confirm peak-load tolerance and protective features respond as expected.
  • Document the installation with panel photos and wiring diagrams for future maintenance, and ensure cable management keeps inputs and outputs segregated from high-noise sources.
  • Regularly inspect terminal connections and enclosure ventilation to prevent heat buildup and maintain reliable operation in continuous-duty applications.

Frequently asked questions

  • Q: What is the output voltage and current rating?

    A: The SDR-480-24 provides a fixed 24 V DC output with a maximum current of 20 A, delivering up to 480 W of power for continuous operation.

  • Q: What input voltage does this supply accept?

    A: It features a universal input range of 85–264 VAC (47–63 Hz), allowing operation across most global electrical standards without external transformers.

  • Q: Does it include protection against electrical faults?

    A: Yes. The SDR-480-24 includes short-circuit protection, overload protection, overvoltage protection, and thermal protection to safeguard both the power supply and connected equipment.

  • Q: What safety features aid in wiring and maintenance?

    A: The unit uses touch-guard screw terminals for safer, tool-friendly field wiring, and a DC OK relay contact provides an easy way to monitor output health from a controller or alarm system.

  • Q: How is the unit installed in an enclosure?

    A: The SDR-480-24 is designed for DIN rail mounting in standard enclosures. It fits on TS-35 rails, making it straightforward to install alongside other DIN-rail components in a control cabinet.

  • Q: Is this supply suitable for peak-load conditions?

    A: Yes. The design includes peak-load capability to handle brief surge currents typical of motors, drives, and other inductive loads without tripping or dropping output, assuming the overall system remains within the unit’s 480 W rating.

  • Q: Are there any certifications?

    A: The SDR-480-24 carries common industrial certifications (such as UL/CE/RoHS family compliance) appropriate for use in global markets and regulated environments.
