A reliable power supply is the foundation of any intercom system. Without stable voltage, the camera, microphone, and door opener remain silent. In this subcategory, UMATECH offers all power solutions for video and audio intercoms, from compact power adapters to professional DIN-rail modules and smart PoE injectors.

• 12V/24V power adapters – ideal for a single outdoor unit or indoor monitor. The stabilized output prevents video flicker and audio hum.
• DIN-rail power supplies – the perfect choice for your meter box or patch panel. Screw terminals allow you to securely connect multiple outdoor stations and locks in parallel. An LED indicator shows power availability at a glance.
• Active & passive PoE injectors – send both power and data over a single network cable; convenient if you don't have a power outlet near your front door. Our 15W and 30W models are short-circuit and surge protected.
• Battery backup modules – keep your intercom online during power outages. The integrated trickle charger continuously monitors the battery, while automatic switchover prevents the intercom from resetting.

All power supplies comply with CE, EMC, and low-voltage directives and come with clear Dutch instructions, mounting brackets, or a plug-and-play DC connector. Need to calculate capacity? Allow roughly 10% margin above the total consumption of the outdoor station, monitor, and lock for long-term reliability. If you're having trouble, the UMA team is available via chat or phone.

If you order before 5 PM (provided it's in stock), we'll ship it the same day – so your intercom will receive the stable power it deserves tomorrow.
