Intercom power supplies

A reliable power supply is the foundation of every intercom system – without stable voltage, camera, microphone and door release stay silent. In this category UMATECH offers all power solutions for video and audio intercoms, from compact plug-in adapters to professional DIN rail modules and smart PoE injectors.

• 12 V / 24 V plug-in adapters – ideal for a single door station or indoor monitor. The regulated output prevents image flicker and audio hum.
• DIN rail power supplies – the perfect choice for the meter cupboard or comms cabinet. Screw terminals let you connect several door stations and locks safely in parallel, and an LED shows at a glance that power is present.
• Active & passive PoE injectors – send power and data over one network cable; handy when there's no socket at the front door. Our 15 W and 30 W models are protected against short circuit and overvoltage.
• Battery backup modules – keep your intercom online during a power cut. The integrated trickle charger monitors the battery continuously, and automatic switchover prevents the door station from resetting.

All power supplies comply with CE, EMC and the Low Voltage Directive and come with a clear manual, mounting brackets or plug-and-play DC connector. Sizing tip: allow roughly 10% headroom above the total consumption of door station, monitor and lock for long-term reliability. Stuck? Our team is ready to help by chat or phone.
