Overview

Upgrade or replace your doorbell power source with the Newhouse 3040TR Dual-Volt Transformer. It offers 16V at 30 VA or 24V at 40 VA, giving essential headroom for modern doorbells that support video, motion sensing, and WiFi connectivity.

Designed to deliver steady low voltage, this transformer helps keep video streams crisp and chimes responsive by providing the power your device may demand as features evolve.

Smart compatibility and dependable performance

Compatible with Ring, Nest, Wyze, Eufy, Arlo, and other video doorbells, ensuring broad compatibility for many homes. The higher VA rating helps maintain consistent performance when doorbells request more power for image quality and quick responses.

  • Available outputs: 16V 30 VA or 24V 40 VA (not both at once).
  • High power capacity reduces under-voltage warnings and camera resets that can occur with smaller transformers.
  • UL Listed Class 2 safety rating supports safe indoor installation in residential spaces.

Installation and safety

The unit mounts on a standard metal junction box with a built in threaded hub, enabling a clean outside installation. Do not install inside a wall, as the transformer generates heat and needs space for ventilation.

  • Outdoor friendly mounting keeps wiring tidy and accessible.
  • Durable metal housing designed for long lasting residential use.
  • Ideal for new installations or replacements in homes upgrading to video doorbells.

Real world benefits you may notice

When video doorbells and smart chimes draw more power, this transformer can help keep streams steady, reduce WiFi dropouts, and minimize resets. It offers a practical upgrade for homes adopting video security and smart doorbells.

UL safety certification and a rugged chassis provide confidence for daily use, while the threaded hub mount simplifies outdoor installation on standard junction boxes. This setup is designed for indoor low voltage power needs and can support a range of popular doorbell models.
