SDC 631RF 1.5 Amp DC Power Controller
Overview
The 631RF is a 1.5 Amp Class 2 regulated DC power controller housed in a 12" × 12" × 4" metal cabinet. It provides field-selectable dual voltage output (12 or 24 VDC) with integrated surge protection and isolated battery charging — essential infrastructure for multi-door access systems that need reliable credential processing power across distributed readers and locks without dedicated UPS infrastructure at each node.
Compatibility
The 631RF works with proximity readers and keypad input devices in access control ecosystems. Input voltage is 115 VAC, 800 mA (50/60 Hz). Available option boards (VR, ACM, EMC, FB, UR1, CR) allow integration into specific platform architectures — verify your access control platform's board compatibility before ordering. The Class 2 output rating means it is suitable for low-voltage locking mechanisms, reader power, and auxiliary circuits in commercial access control deployments.
Installation Notes
Cabinet dimensions are 12" × 12" × 4" in 20-gauge steel, weighing 9 lbs — plan mounting space accordingly. Dual voltage is field-selectable, so set output to match your reader and strike voltage before final installation. The isolated battery charging circuit (13.5/27 VDC, 250 mA) supports battery backup; configure low-battery disconnect per your system's failsafe requirement. LED status indicator provides visual feedback; remote annunciation outputs allow integration into building monitoring systems. Optional accessories include key lock cover (KL), 6-foot power cord (PC), and power on/off switches (PS1/PS1A) — order separately as needed.
