Trust in this DIN rail transformer from ABB when secure voltage conversions are your top priority. You can use it to step down 230V AC of mains power to a stable 12 to 24V AC – just the ticket for tasks involving small discontinuous loads. It's kitted out with double isolation between its primary and secondary windings to boost electrical safety. A built-in SELV circuit also provides earthing protection that keeps you and your equipment safe and sound by preventing electric shocks. The unit's rating of 40W makes it a practical pick for your low-power industrial applications.

• Snaps simply onto a DIN rail without tools
• Class B insulation makes it safe in harsh environments up to +130°C
• Guided terminal holes help avoid wiring mishaps for easy termination
• IP20-rated, so is finger-safe and protected against objects larger than 12mm

• Doorbells
• HVAC systems
• Medical devices

Thanks to its fail-safe behaviour, you can be sure this product will stop functioning whenever an overload or short-circuit fault occurs. This minimises your risk of electric shocks.
