If you need a secure power conversion solution, this DIN rail transformer from ABB will do the trick. It steps down 230V AC inputs from your mains supply into stable secondary voltages of 12 to 24V AC. This makes it a good fit for intermittent applications or discontinuous loads like doorbells. As a fail-safe transformer, it won't function in overload or short-circuit conditions making it a practical pick for protecting you and any connected equipment. Thanks to dependable double isolation between this module's primary and secondary windings, you can rest assured your risk of accidental contact with live elements is minimised. Its Class B insulation rating means it works in temperatures up to +130°C so you know it can handle the heat in harsh environments.

• 30W rating means it's suitable for low-power applications
• IP20 approval assures you terminals are touch-safe and protected against objects larger than 12mm
• DIN rail mounting for installation in a snap
• Handy label space on consumer unit helps with device organisation

• HVAC systems
• Process control
• Power testing devices
