PSU2 12V DC 1A Model Railway Power Supply

About the Product

The BLOCKsignalling PSU2 is a regulated 12V DC 1A model railway power supply with up to 12W output and a 5.5mm × 2.1mm centre-positive DC plug. It is designed for BLOCKsignalling modules and other compatible 12V DC model railway accessories.

Providing up to 12W of regulated DC power, the PSU2 maintains a stable 12V output to help ensure reliable operation of connected electronics. It is fitted with a standard 5.5mm × 2.1mm centre-positive DC plug, making it directly compatible with a range of BLOCKsignalling modules.

Unlike some power supplies, the PSU2 does not require a minimum load to operate correctly and maintains its regulated output even when little or no load is connected.

The compact plug-top design incorporates a fixed UK Type G mains plug and accepts an input voltage of 90-264V AC.
