RSA-25D-C 25W Dual-Output Switching Power Supply – 24V & 5V DC

The RSA-25D-C is a compact dual-output switching power supply designed to provide 24V DC and 5V DC power for compatible CO2 laser machines, control systems, and electronic components requiring two voltage levels.

This 25W-class power supply accepts 110V or 220V AC input as specified in the original product listing. Its dual-output configuration allows compatible equipment to receive 24V and 5V DC power from a single supply rather than requiring two separate power supplies.

The unit features a ventilated metal enclosure, screw-terminal connections, and an LED output indicator. The existing specifications also list overcurrent and overvoltage protection.

Important: This power supply is listed as a 25W unit with individual output ratings of 24V at 1A and 5V at 1A. Those ratings add up to 29W if both outputs are fully loaded. Verify the manufacturer's combined-load limits before operating both outputs at their maximum listed currents.

Understanding the Dual-Output Design

Laser machines may require different DC voltages for their electrical components. A 24V supply may be used for compatible controllers or control circuits, while a 5V supply may be used for lower-voltage electronics and accessories.

The RSA-25D-C provides both voltage outputs within one power supply enclosure, reducing the need for separate power supplies when the connected equipment is designed for this configuration.

Each output must be connected only to equipment rated for its corresponding voltage. Connecting a 5V component to the 24V output may permanently damage the component.

Understanding the power rating: The manufacturer's total rated output power and individual output current limits must both be respected. Do not assume that each output can continuously deliver its maximum listed current at the same time.

Compatibility

This power supply is intended for compatible CO2 laser engraving and cutting machines requiring both 24V DC and 5V DC outputs.

Before ordering, compare the replacement power supply with your original component:

• RSA-25D-C model number
• 110V or 220V AC input requirements
• 24V DC output rating
• 5V DC output rating
• Combined output power and current requirements
• AC input and DC output terminal positions
• Physical dimensions and mounting locations
• Required electrical protection features
• Available ventilation space inside the electrical cabinet

Important: A dual-output power supply with similar dimensions or voltage markings is not necessarily an interchangeable replacement. Different models may have different total power ratings, output limits, and terminal arrangements.

Do not substitute a single-output 24V or 5V power supply for this dual-output model unless the complete electrical system has been evaluated and the replacement configuration is appropriate.

Installation & Safety

• Disconnect the laser machine from its electrical supply before inspecting or replacing the power supply.
• Allow stored electrical energy to discharge according to the equipment manufacturer's instructions.
• Verify the input voltage rating and any voltage selection setting before applying power.
• Identify the AC input, protective ground, 24V output, and 5V output terminals using the markings on the actual unit.
• Confirm correct DC output polarity before reconnecting equipment.
• Do not exceed individual output current ratings or the manufacturer's combined output power limit.
• Maintain adequate airflow around the ventilated enclosure.
• Keep the power supply away from moisture, conductive debris, and loose metal objects.
• Secure the power supply using the correct mounting hardware.
• Have installation and troubleshooting performed by someone experienced with electrical control systems.

Safety Note: This power supply contains hazardous AC voltage circuitry. Disconnect electrical power before servicing, and do not touch internal components or exposed terminals while energized.

If the replacement power supply fails, overheats, or produces an incorrect output voltage, inspect the connected wiring and electrical loads before installing another replacement.
