SDC 631RF Series 1.5 Amp Regulated & Filtered DC Power Controller with Dual Voltage Selection

Professional DC Power Controller for Access Control Systems

The SDC 631RF Series DC Power Controller delivers highly regulated and filtered low-voltage DC output specifically engineered for electronic access control systems. This 1.5 amp power controller features dual voltage field selectable operation (12VDC or 24VDC) with hybrid linear/switching power supply design to provide steady, clean power for electric locks, maglocks, door hardware, and life safety equipment. Available in three configurations including cabinet models (631RF, 631RFA) and panel integration model (631RFL), this power controller addresses voltage spikes and current instability issues responsible for up to 85% of access control technical support calls.

Professional Features & Benefits

  • Dual Voltage Operation: Field selectable 12VDC or 24VDC output provides flexibility for various access control system requirements and device compatibility.
  • 1.5 Amp Current Capacity: Reliable 1.5A output delivers sufficient power for multi-door access control systems and high-current locking devices.
  • Regulated and Filtered Output: Hybrid linear/switching power supply design provides highly regulated and filtered DC power to protect sensitive circuitry in access control panels and locking devices.
  • Surge Protection: Built-in surge protection on both input and output lines prevents damage from voltage spikes and transients that cause system failures.
  • Fire/Emergency Release Integration: Dedicated fire/emergency release input enables automatic override during fire alarm activation for life safety compliance.
  • Class 2 Power Output: UL Class 2 rated output suitable for low-voltage system installations with simplified wiring requirements.
  • Battery Backup Support: Isolated battery charging circuit with low battery disconnect ensures continued operation during power outages.
  • Multiple Configuration Options: Available as 631RF with cabinet, 631RFA with large cabinet, or 631RFL less cabinet for panel integration flexibility.

SDC 631RFXPS-1XPCXKL – Frequently Asked Questions

1) What is the SDC 631 series power supply used for?
The SDC 631 series provides 1.5 amp regulated and filtered low voltage DC power for access control systems, card readers, electric strikes, and door hardware. It converts standard AC line voltage to clean 12VDC or 24VDC output.
2) What voltage outputs are available with this power supply?
The 631 series typically offers selectable 12VDC or 24VDC output options. Check the specific model number to confirm voltage rating. Maximum current output is 1.5 amps continuous.
3) Can this power supply handle electric strike loads?
Yes, the regulated filtered output handles electric strike inrush currents effectively. The 1.5 amp rating supports most standard strikes. Verify your strike's current draw specifications before installation.
4) How do you mount the SDC 631 series power supply?
The unit typically mounts inside electrical enclosures or junction boxes using provided mounting tabs. Ensure adequate ventilation space around the transformer. Mount in dry locations only.
5) What wire gauge should be used with this power supply?
Use 18 AWG minimum for DC output connections up to 50 feet. Longer runs may require 16 AWG or larger to prevent voltage drop. AC input connections follow local electrical codes for low voltage transformers.
6) Does this power supply include surge protection?
The filtered design provides basic line conditioning. For enhanced protection in surge-prone areas, consider adding dedicated surge suppressors. Check manufacturer specifications for built-in protection features.
7) Can multiple devices be powered from one 631 series unit?
Yes, you can power multiple devices provided total current draw stays under 1.5 amps. Use proper distribution blocks or terminal strips. Calculate each device's current requirement before connecting.
8) What are the typical dimensions of this power supply?
Dimensions vary by specific model within the 631 series. Most are compact designs suitable for standard electrical boxes. Verify exact measurements from manufacturer specifications before ordering enclosures.
9) How do you test the SDC 631 series power supply output?
Use a digital multimeter to measure DC voltage at output terminals. Voltage should be within 5% of rated output under load. Check both no-load and full-load conditions during testing.
10) Are there higher amperage versions in the SDC series?
SDC offers various amperage ratings across their power supply line. Browse our SDC products section for 2.5 amp, 5 amp, and higher capacity models for larger installations.
11) What maintenance does this power supply require?
Keep unit dust-free and ensure ventilation openings remain clear. Check mounting hardware periodically. No internal maintenance required. Replace unit if output voltage becomes unstable or drops significantly under load.
