Power supply unit Satel APS-612 Wired 265V White 122mm x 84mm x 78mm

The SATEL Power supply unit APS-612 is a wired backup power supply designed for smart home, security and industrial applications. It provides 12 V DC output with a combined 6 A capacity — 3 A dedicated for powering connected devices and 3 A for battery charging — and is compatible with loads used in alarm systems, access control and CCTV. The unit uses an LLC topology SMPS for high efficiency and low heat generation, includes active PFC at the input, a noise filter, short-circuit and overload protection, and accepts a battery connected directly for uninterrupted operation.

Advantages

APS-612 meets EN 50131-3 Grade 3 requirements and incorporates microprocessor control of battery status and operation, precise voltage regulation and automatic battery disconnection in case of excessive discharge. Built-in diagnostics use LEDs and acoustic signaling to report mains presence, battery condition and fault states such as overheating, overload or short-circuit. Four open-collector outputs provide fault notification to an alarm system. The integrated 3-pin connector enables direct connection to compatible SATEL devices such as zone/output expanders and ACCO-NT access control panels.

Suitable for

• Wired alarm and intrusion detection systems
• Access control panels and door entry systems
• CCTV camera and recording equipment
• Critical infrastructure and industrial automation
• Laboratory devices requiring stable 12 V DC supply

How to use

Install the APS-612 in a ventilated, dry location complying with local electrical regulations and ensure the mains supply is disconnected before wiring. Connect the 230 V AC mains input and mount the battery directly to the dedicated terminals, observing correct polarity. Use the 3-pin connector to link compatible SATEL devices when required. After wiring, power the unit and verify LED indicators for mains presence and battery condition; monitor the open-collector outputs for integration with an alarm control panel. Regularly check for acoustic and LED fault signals and follow standard maintenance procedures for the connected battery.

Recommendations

For reliable operation, use a battery recommended by the manufacturer and install the unit in an environment within the specified temperature range. Keep ventilation paths clear to prevent overheating, perform periodical battery tests, and integrate fault outputs with your alarm or control system to ensure timely detection of mains loss, overloads or battery issues.
