Doorbell Transformer ZAMEL TRM-24 230V to 24V AC, 15 VA

ZAMEL TRM-24 is a doorbell transformer that converts standard mains voltage (230 V) to 24 V AC with a rated output of 15 VA. It is intended to provide a stable low-voltage supply for door chimes and other low-voltage signaling devices in residential and light commercial installations. The unit is designed for mounting inside electrical enclosures and for integration into existing doorbell circuits where a reliable 24 V AC source is required.

Advantages

The transformer delivers a fixed 24 V AC output at up to 15 VA, ensuring compatibility with common door chimes and signaling devices. Its compact design allows installation inside distribution boxes or service panels, reducing the need for additional enclosure space. Built for mains-to-low-voltage conversion, it provides electrical isolation between the primary and secondary circuits and supports continuous or intermittent operation typical for doorbell use.

Suitable for

• Powering mechanical and electronic door chimes
• Low-voltage signaling devices in homes or small commercial premises
• Integration into doorbell circuits and access control systems
• Mounting inside electrical distribution enclosures

Key specifications

• Input voltage: 230 V AC mains
• Output voltage: 24 V AC
• Rated output power: 15 VA
• Intended application: doorbell and low-voltage signaling supply
• Mounting: suitable for installation inside electrical enclosures

How to use

Install the transformer inside an appropriate electrical enclosure according to local wiring regulations. Connect the primary side to the 230 V AC mains supply with correct fuse protection and earth as required. Connect the secondary 24 V AC terminals to the door chime or signaling device, observing polarity if applicable and ensuring the connected load does not exceed 15 VA. Test the doorbell circuit after installation and verify safe operation before closing the enclosure.

Usage recommendations

Use appropriate protective devices on the mains side and confirm that the total load on the 24 V output stays within the 15 VA rating. For permanent installations, follow local electrical codes and, if necessary, engage a qualified electrician to perform mounting and wiring.
