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 INPUTA fire alarm input provides simultaneous release of all fail safelocks and door holders in case of an emergency. An optionalmanual reset switch following a fire/emergency release orpower loss is available to meet code compliance. When theoptional manual reset feature is required, should an AC powerloss occur or the emergency release input be actuated,personnel must restore secondary output power manually atthe power supply after the emergency release signal is resetand/or AC power is restored.ISOLATED BATTERY CHARGING CIRCUITA separate charging output provides 13.5 or 27 volts tofully charge the batteries. The secondary output is alwaysprecisely maintained at 12 or 24VDC to protect lockingdevices and components from over voltage while thebatteries are charging. The specified secondary outputcurrent is also maintained while batteries are charging. Derating of the secondary output current is not required whencharging batteries.LOW BATTERY DISCONNECTBatteries are disconnected from the output circuit prior todeep discharge, preventing battery destruction. Batteries arenot included and should be ordered separately.*DOOR CONTROL MODULESDoor control relay modules are available to meet virtuallyany application need. All wiring for lock hardware, accesscontrols, remote controls and monitoring is terminated at onecentral location. Installation and troubleshooting is simplified.Modules may be factory installed or ordered separately forfield installation as needed. Cabinet enclosures are preconfigured with mounting holes to accommodate doorcontrol modules. All modules are individually fused forprotection of multiple station systems.INPUT & OUTPUT SURGE PROTECTIONInput and output surge protection is built-in. The AC inputvoltage is circuit breaker protected and the outputs are PTCprotected.VISUAL STATUS INDICATOR (LED)LED tri-color status indicators provide information regardingthe AC input, DC output and battery backup status. Outputsfor remote annunciation are available.SYSTEM ON/OFF SWITCHESOptional System On/Off switches are available both insidethe cabinet enclosure or on the cabinet enclosure cover.KEY LOCK COVEROptional key lock cover available where tamper-resistance isrequired.INTERNATIONAL STANDARD INPUTAdditionally an alternative 230VAC international standardinput is an available option.
