Relco RN9140 Micro LED Transformer 12V AC 20–105W Dimmable – Electronic Transformer for LED & Halogen

RELCO RN9140 Micro LED Transformer 12 V AC Dimmable Overview

The RELCO RN9140 Micro LED Transformer 105 PFS is a compact electronic transformer for suitable LED and halogen lighting with 12 V AC. It converts an input voltage of 220–240 V AC into 12 V AC alternating current and is suitable for recessed spotlights, furniture lighting, ceiling lights, and other compatible low-voltage lighting systems.

The transformer supports dimmable 12 V AC LED bulbs with approx. 3–55 W as well as low-voltage halogen lamps in the power range of 20–105 W. Thanks to its compact design, it is particularly well-suited for integration into suitable luminaires and existing lighting systems.

Dimmable 12 V AC Transformer for LED and Halogen

The electronic transformer is designed for LED and halogen bulbs with 12 V AC. Brightness control is achieved via compatible leading-edge or TRIAC dimming. For LED bulbs, it must be ensured that they are explicitly marked as dimmable and suitable for operation at 12 V AC.

LED Power Range from 3 to 55 W

For compatible LED bulbs, the RN9140 offers a power range of approx. 3 to 55 W. This makes it suitable for both individual low-voltage LED spots and appropriate lighting systems with multiple bulbs, provided the technical requirements are met.

For Low-Voltage Halogen up to 105 W

Classic 12 V halogen lighting can also be operated with this electronic transformer. A power range of 20 to 105 W is intended for halogen bulbs, making the device also suitable as a replacement transformer for existing low-voltage halogen installations.

Integrated Protection Functions

The RELCO RN9140 features protective functions against short circuits, overload, overvoltage, and overheating. Protection class II and the IP20 rating signify its design for use in dry indoor areas.

Typical Applications

• 12 V AC LED spots
• Low-voltage halogen lights
• Recessed lights and ceiling spots

Important Note

The transformer provides exclusively 12 V AC alternating voltage. It is therefore not intended for 12 V DC LED strips or other consumers that strictly require 12 V direct current.

For dimming operation, only suitable and explicitly dimmable 12 V AC LED bulbs may be used. Before replacing an existing transformer, check the output voltage, power range, dimming technology, and the requirements of the connected bulbs. Due to the IP20 rating, the device is intended exclusively for dry indoor areas.

Frequently Asked Questions

Is the RELCO RN9140 suitable for LED bulbs?

Yes, the RELCO RN9140 is suitable for compatible LED bulbs explicitly designed for 12 V AC with a total power output of approx. 3 to 55 W.

Can the transformer be dimmed?

Yes, the RELCO RN9140 is dimmable and can be used in a compatible leading-edge or TRIAC dimming installation.

Can the RN9140 also power halogen bulbs?

Yes, the transformer is intended for suitable 12 V low-voltage halogen lamps with a total power output of 20 to 105 W.

Can the transformer be used for 12 V DC LED strips?

No, the RN9140 supplies 12 V AC alternating voltage and is therefore not suitable for LED strips or other consumers that explicitly require 12 V DC.
