Access control system power requirements are uniquely different from other systems. Unlike camera system power requirements, access control systems draw more current for locking hardware and during access control-related events. 75 – 85% of access control operating problems and technical support calls are due to power issues.* Access control systems require steady and clean (filtered) low-voltage DC current with surge suppression to protect
printed circuit boards and connected devices from damage due to dirty power (transients and voltage spikes).
SDC power supplies have been developed specifically to help reduce power system issues and to support electric locks and access control requirements. Our hybrid design combines the efficiency of switching power supplies with the inductive load handling capability of linear power supplies in various 12/24 VDC current output capabilities and enclosure sizes. Filtering and output voltage regulation provide protection and ensure the longevity of all
system components.
The high performance, heavy-duty circuitry is ideal for inductive loads and multi-door applications. With the addition of SDC programmable controllers or relay modules, the user-friendly modular designs ensure versatility, interface capability and easy installation of virtually any electric locking devices, access controls and related fire & life safety equipment.

FIRE/EMERGENCY RELEASE INPUT
A fire alarm input provides simultaneous release of all fail safe
locks and door holders in case of an emergency. An optional
manual reset switch following a fire/emergency release or
power loss is available to meet code compliance. When the
optional manual reset feature is required, should an AC power
loss occur or the emergency release input be 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.
ISOLATED BATTERY CHARGING CIRCUIT
A separate charging output provides 13.5 or 27 volts to
fully charge the batteries. The secondary output is always
precisely maintained at 12 or 24VDC to protect locking
devices and components from over voltage while the
batteries are charging. The specified secondary output
current is also maintained while batteries are charging. Derating of the secondary output current is not required when
charging batteries.
LOW BATTERY DISCONNECT
Batteries are disconnected from the output circuit prior to
deep discharge preventing battery destruction. Batteries are
not included and should be ordered separately.*
DOOR CONTROL MODULES
Door control relay modules are available to meet virtually
any application need. All wiring for lock hardware, access
controls, remote controls and monitoring is terminated at one
central location. Installation and troubleshooting is simplified.
Modules may be factory installed or ordered separately for
field installation as needed. Cabinet enclosures are preconfigured with mounting holes to accommodate door
control modules. All modules are individually fused for
protection of multiple station systems.
INPUT & OUTPUT SURGE PROTECTION
Input and output surge protection is built-in. The AC input
voltage is circuit breaker protected and the outputs are PTC
protected.
VISUAL STATUS INDICATOR (LED)
LED tri-color status indicators provide information regarding
the AC input, DC output and battery backup status.
SYSTEM ON/OFF SWITCHES
Optional System On/Off switches are available both inside
the cabinet enclosure or on the cabinet enclosure cover.
6’ POWER CORD
An optional 6’ power cord simplifies installations that do not
require conduit where permitted by code.
KEY LOCK COVER
Optional key lock cover available where tamper-resistance is
required.
INTERNATIONAL STANDARD INPUT
Additionally an alternative 230VAC international standard
input is an available option.
