The SDC 631RF Power Supplies have been developed specifically to support electric locks and access controls. The high performance, heavy-duty circuitry is ideal for inductive loads and multi-door applications. The modular design is built around several different application control modules to meet your specific needs for virtually any electric lock system. SDC power supplies are designed to provide a well organized installation for individual or multidoor systems that may include locking devices, access controls, station controls and consoles for remote control, annunciation and fire/life safety system interfaces.

FEATURES | Filtered and Regulated

The output filtering stabilizes the DC output voltage and eliminates AC line noise. The solid state regulator maintains the selected output voltage at 12VDC or 24VDC regardless of the output load changes, including battery charging.

Field Selectable

12 or 24VDC The output is field selectable for 12 or 24VDC output

250 mA Battery Charger Output

A separate PTC protected, battery charger output provides 13.5VDC or 27VDC.

LED System Status Indicator

• Amber - AC and DC voltages are OK
• Green - No DC output
• Red - No AC input, powered by batteries

Class 2 Outputs

Where permitted by code, conduit is not required when using Class 2 outputs.

Emergency Release Input

The Fire/Life Safety emergency release input is standard on all SDC power supplies.

Large Heavy Gauge Enclosure

Model 631RFA is housed in a 16 gauge, 16" W x 14" H x 6.5" D cabinet large enough to accommodate several additional modules and four 8Amp hour batteries with plenty of room for wiring.

Low Battery Disconnect

Batteries are disconnected from the output circuit prior to deep discharge preventing battery destruction.

Isolated Charging Circuit

While the charging output is 13.5VDC or 27VDC, the secondary output is unaffected and precisely maintained at the selected 12 or 24VDC. This ensures system components are powered by their specified voltage. The secondary output current is maintained at the full 1.5 Amp capacity and is not de-rated when charging batteries.
