Power supply QOLTEC 54471 12V 2A compact design

The QOLTEC 54471 mains power supply provides a stabilized 12 V DC output with a maximum current of 2 A in a compact housing. Designed for powering small electronics such as routers, CCTV cameras and other devices that require a steady 12 V source, this unit offers a space-saving form factor for convenient placement in home and office environments. Built-in basic protections guard against short-circuit and overload conditions while maintaining stable output for reliable operation.

Advantages

The compact design of the QOLTEC 54471 reduces installation space and simplifies placement near end devices. Stable 12 V output with a 2 A rating supports continuous operation of low-power network equipment and surveillance devices. Integrated short-circuit and overload protection help prevent damage to the power supply and connected equipment under fault conditions. The straightforward construction and standardized output make the unit compatible with a wide range of consumer and commercial electronics that accept a 12 V DC feed.

Suitable for

• Routers and modems that require a 12 V DC input
• CCTV and IP cameras with low power consumption
• Small audio devices and media players designed for external adapters
• LED drivers and small lighting modules compatible with 12 V DC
• Prototype electronics and development boards needing a stabilized 12 V supply

Key specifications

• Output voltage: 12 V DC
• Maximum output current: 2 A
• Form factor: compact, space-saving housing
• Protection features: basic short-circuit and overload protection
• Intended use: mains-powered external adapter for small electronic devices

How to use

Connect the power supply to a compatible mains socket and attach the output plug to the device that requires 12 V DC power, observing correct polarity. Ensure the device’s power requirements do not exceed 2 A continuous current. Place the adapter in a well-ventilated area free from moisture and excessive dust, and avoid covering the housing during operation to maintain cooling. If the unit trips due to an overload or short-circuit, disconnect the load, remove the fault, and reconnect the adapter following the device manufacturer’s instructions.

Usage recommendations

Verify the voltage and polarity requirements of the target device before connection. Use only with devices rated for a 12 V DC input and a current draw within the 2 A limit. For permanent installations, check that the outlet and cable routing comply with local electrical regulations and avoid exposure to water or extreme temperatures.
