Power adapter Voltcraft VC-15304175 fixed output 5.1V/9V/12V/15V DC 5A 27W compatible with Raspberry Pi

The Voltcraft VC-15304175 is a mains power adapter with fixed selectable DC output voltages of 5.1 V, 9 V, 12 V or 15 V and a maximum current of 5 A with up to 27 W output. It is designed to provide a stable DC supply for single-board computers, development boards and small electronic devices that accept these voltages. The adapter includes a standard barrel connector and offers overcurrent and short-circuit protection to maintain reliable operation during prototyping, testing and light-duty installations.

Advantages

The adapter delivers stable, selectable DC voltages suited to a range of devices, reducing the need to keep multiple dedicated power supplies. With a 5 A maximum current rating it supports higher-load peripherals such as external drives or add-on boards when used with compatible single-board computers. Built-in protection features and a compact mains plug design make it convenient for bench work and small deployments while minimising the risk of damage from overloads or accidental short circuits.

Suitable for

• Powering Raspberry Pi models and other single-board computers that accept 5.1 V, 9 V, 12 V or 15 V DC
• Development and prototyping of electronic projects and maker boards
• Supplying small network devices, routers or switches that match the voltage and polarity
• Bench testing of peripherals, sensors and add-on modules requiring up to 5 A

When it may not be suitable

This adapter is not appropriate for devices that require voltages or connectors outside the selectable 5.1 V–15 V range, or for equipment that demands power well above 27 W. It also may not suit systems that need adjustable voltage under load with fine control or programmable sequencing. Verify connector polarity and centre/outer pin dimensions before connecting to sensitive electronics.

Key specifications

• Output voltages: selectable 5.1 V, 9 V, 12 V, 15 V DC
• Maximum output current: 5 A
• Maximum continuous output power: 27 W
• Connector type: barrel-style DC plug (verify size and polarity for compatibility)
• Protection: overcurrent and short-circuit protection
• Intended use: mains-powered adapter for electronics and single-board computers

How to use

Select the required output voltage according to the device specification before connecting the adapter to the mains. Confirm the barrel connector dimensions and polarity match the target device. Connect the adapter to the device while the mains plug is disconnected, then plug into the mains supply and switch on. Monitor initial operation for any signs of heat, noise or malfunction and disconnect immediately if abnormal behaviour occurs. For prolonged projects ensure ventilation and avoid covering the adapter during operation.

What to consider before purchase

• Confirm your device accepts one of the available output voltages (5.1 V, 9 V, 12 V or 15 V)
• Verify barrel connector size and polarity match the device input
• Ensure the device's current draw does not exceed 5 A and total power requirement is within 27 W
• Check whether a regulated, adjustable or higher-power supply is required for your application

Usage recommendations

Use the adapter with devices that specify one of the selectable voltages and have compatible connector/polarity. For Raspberry Pi and similar single-board computers, prefer the 5.1 V setting and verify that peripheral current draw remains under the 5 A limit. Allow adequate ventilation and avoid continuous operation at full load without monitoring temperature. If precise voltage regulation or sequencing is required, consider a laboratory bench supply instead.
