Bailey 145683 Electronic Transformer Light Control

Product Information
The TOPO Electronic Transformer is designed for use with 12V halogen and LED lamps, with a power range of 0-50W. The transformer has a primary voltage range of 220V-240V and a secondary voltage of 11.5V. It has an output current of 4.3A at full load and an IP20 rating. The transformer is dimmable with most leading/trailing edge dimmers and has a primary input current of 0.23A. The transformer has an output frequency of 30-200cm and an efficiency rating that meets standards EN 61347-1, EN 61347-2-2, EN 62493, EN 55015, EN 61000-3-2, EN 61000-3-3, and EN 61547. It has a power factor, input capacitance, and overload protection with short circuit protection. The transformer has a maximum ambient temperature (ta) and case temperature (tc) for safe usage.
Product Usage
- Before installation, read the specifications to ensure the product is suitable for the operating environment.
- Installation should be done by a qualified professional to avoid any risk of injury or property damage.
- Wet applications require an IP-rated fixture.
- Install the transformer in places with good airflow and away from heat sources.
- The transformer must be installed above the insulation.
- The dimmer should be installed on the power input wire leading to the transformer.
- If flickering or noise occurs, it means the transformer is not compatible with the used LED lamp and/or LED dimmer.
For any additional information or assistance, refer to the installation manual or contact Bailey Electric & Electronics bv.
