SDC 631RF Power Supply, 1.5 Amp, 12/24 VDC Field Selectable, Class 2 Output, with 12 In. Wide by 12 In. high by 3.75 In. Deep Box

The SDC 631RF is a 1.5 Amp Regulated and Filtered Low Voltage Power Supply specifically designed to support electric locks and access control systems. Its high-performance, heavy-duty circuitry is ideal for inductive loads and multi-door applications.

• Filtered and Regulated Output: Provides stabilized DC output voltage, eliminating AC line noise, and maintains selected output voltage (12VDC or 24VDC) regardless of load changes, including battery charging.
• Battery Charger Output: Includes a separate 250mA PTC-protected battery charger output providing 13.5VDC or 27VDC, ensuring batteries are maintained without affecting the main output.
• Low Battery Disconnect: Automatically disconnects batteries from the secondary output circuit when voltage decreases below 70%, ensuring batteries are capable of recharging.
• LED System Status Indicator: Provides visual status with amber indicating AC and DC voltages are OK, green for no DC output, and red for no AC input (powered by batteries).
• Emergency Release Input: Standard feature for fire/life safety system integration, allowing for immediate unlocking in emergencies.
• Field Selectable Output: Output voltage is field selectable for 12VDC or 24VDC to suit various system requirements.
