Power supply unit Satel APS-30 230V White 324x382x108mm

The SATEL APS-30 power supply unit is designed to provide stable 12 V DC power for devices used in alarm, video and intercom systems. It accepts AC input in the 17–20 V range and delivers a regulated DC output with a maximum current of 3 A. The unit incorporates a high-efficiency switching power supply to ensure good power performance with low thermal losses, and it is housed in a white enclosure measuring 324 × 382 × 108 mm for convenient installation in residential or commercial environments.

Advantages

The APS-30 features short-circuit and overload protection, microprocessor-controlled battery charging and automatic disconnection to prevent excessive battery discharge. LED indicators report mains presence, battery presence and charging activity, while acoustic signaling notifies of detected faults. Two OC type outputs supply alarm systems with status changes for mains failure or battery voltage drop, facilitating system integration and remote monitoring.

Suitable for

• Powering alarm control panels and sensors in small to medium security systems
• Supplying video recorders, cameras and intercom units that require 12 V DC
• Applications where compact, wall- or cabinet-mounted power supplies are needed
• Installations that benefit from battery backup and battery health management

How to use

Mount the APS-30 in a suitable location inside a cabinet or on a wall, ensuring adequate ventilation and access to the tamper switch if required. Connect the AC input within the specified 17–20 V range and connect the 12 V DC output to the devices to be powered, observing correct polarity. Connect a compatible lead-acid battery to the battery terminals to enable backup functionality; the microprocessor-controlled charger will manage charging and perform periodic battery tests. Configure the alarm system to monitor the OC outputs for mains loss and low battery signals.

Usage recommendations

Use sealed lead-acid batteries recommended by the system designer or SATEL, check connections and mounting periodically, and avoid placing the unit in areas with extreme temperatures or excessive humidity. Regularly inspect LED indicators and address any acoustic fault signals promptly to maintain reliable backup power for your alarm, video or intercom system.
