## Summary description

ORNO OR-PSU-1646 is a DIN-rail mounted power supply delivering 24 V DC at up to 0.63 A (15 W). Designed for industrial and building automation applications, it provides a compact fixed-output source for controllers, sensors, relays and low-power modules. The unit is intended for installation on standard DIN rails and suitable where a stable 24 V DC feed is required.

## Long description

ORNO OR-PSU-1646 is a DIN-rail mounted power supply that provides a fixed 24 V DC output with a maximum current of 0.63 A and nominal output power of 15 W. The compact unit is intended for installation on standard DIN rails in control cabinets and distribution enclosures where a stable low-power 24 V feed is required for industrial and building automation equipment such as controllers, sensors, relays and small modules.
Advantages
The device offers a compact footprint suitable for space-constrained enclosures and straightforward DIN-rail mounting for quick integration into existing installations. Its fixed 24 V output eliminates the need for additional voltage regulation for compatible devices, and short-circuit and overload protection ensure reliable operation for low-power loads. The design supports continuous operation for auxiliary circuits and small control electronics.
Suitable for
 Powering PLCs, logic controllers and small automation modules
 Supplying sensors, transmitters and measurement devices in control panels
 Feeding relays, contactors' coils and signal conditioning modules
 Providing a local 24 V supply for building automation and alarm systems
Key specifications
 Output voltage: 24 V DC
 Maximum output current: 0.63 A
 Output power: 15 W
 Mounting: DIN-rail (standard rail profile)
 Fixed-output type (no user-adjustable voltage)
 Intended use: low-power auxiliary supply for control equipment
How to use
Install the power supply on a standard DIN rail inside the control cabinet and secure it according to the enclosure design. Connect the AC mains input to the designated input terminals following local wiring standards and ensuring correct protective earthing. Connect the 24 V DC output to the load using appropriately sized conductors and observe polarity. Verify that the connected devices do not exceed the 0.63 A rating and that wiring and protective devices conform to applicable regulations before energizing the unit.
Usage recommendations
Place the unit in a ventilated area within the cabinet and avoid mounting directly adjacent to heat-generating equipment. Use short, properly sized wiring for the DC output to minimise voltage drop. For applications near the 0.63 A limit, allow margin for inrush currents of connected devices and consider using protection devices or a higher-capacity supply if sustained higher currents are expected.
