ABB 10W Bell Transformer, CE, 230V Primary, 12 → 24V ac Secondary

Need a transformer to step down your mains supply for use with a discontinuous load like a doorbell? Try this DIN rail bell transformer from ABB. It's a practical option for low-voltage intermittent applications as it steps down a primary voltage of 230V AC to a lower secondary voltage output of 12 or 24V AC. The sealed terminal holes support accurate wiring, so it's quick to install and safe to operate. Double isolation between the primary and secondary windings makes this transformer electrically safe, as it poses no risk of harm to you or your surroundings. To fully eliminate the chance of electric shock, it won't function in overload or short-circuit conditions.

• IP20-rated, so it's finger-safe and protected against objects larger than 12mm
• SELV circuit provides earthing and protects users against the risk of electric shock
• Room for a label to help with identification and organisation
• Class B insulator has a maximum allowable temperature of +130°C for use in harsh environments

• Domestic circuits
• HVAC systems
• Discontinuous loads

Yes, this transformer's compact dimensions of 85 (H) x 36 (W) x 65mm (D) and practical DIN-rail mounting style make it easy to fit into a crowded setup.
