SDC 632RF Power Supply, Modular Design, 12V/24V DC Selectable Output, LED Status Indicator, Compatible with Locking Devices & Access Controls, UL Listed – 632RFL (5 Year Warranty)

Description

The SDC 632RF 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 its modular design provides a well organized installation for individual or multi-door systems that may include locking devices, access controls, station controls and consoles for remote control, annunciation and fire/life safety system interfaces.

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.

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

Emergency Release Input (Standard)

A signal input from the fire life safety system turns off the secondary output releasing all failsafe locks. When not used for emergency release, this input may be used as main on-off control.

Large Heavy Gauge Enclosure

Model 632RFA is housed in a 16 gauge, 16″W x 14″H x 6.5″D cabinet large enough to accommodate several additional modules and six 8 Amp hour batteries with plenty of room for wiring.

Class 2 Output

Where permitted by code, conduit is not required for the Class 2 output.

California Compliant Manual Reset of Emergency Release and AC Power Loss (Optional)

When this feature is required, should an AC power loss occur or the emergency release input is actuated, personnel must restore secondary output power manually at the power supply after the emergency release signal is reset and/or AC power is restored.

Low Battery Disconnect (Standard)

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

Isolated Charging Circuit (Standard)

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 2 Amp capacity and is not de-rated when charging batteries.
