Power Supply No name GV6-12V/6.25A — Switching AC-DC 12V 6.25A

The Power Supply No name GV6-12V/6.25A — Switching AC-DC 12V 6.25A is a compact switch-mode power supply that converts mains AC to regulated 12 V DC with a maximum output current of 6.25 A. Designed for fixed installations, the unit provides low-voltage DC suitable for powering CCTV cameras, LED strips, routers and a wide range of other 12 V devices. The switching design ensures efficient conversion with reduced heat generation compared to linear supplies and includes basic protections expected in appliances for continuous low-voltage operation.

Advantages

The switch-mode construction delivers stable 12 V output with good regulation over typical mains voltage fluctuations, while maintaining relatively compact size and efficiency. The rated 6.25 A output supports multiple small loads or mid-power single devices without needing a bulky transformer. Its form factor is suitable for mounting in equipment cabinets or behind panels in permanent installations. Built-in protections typical for switching supplies help reduce risk of damage from short circuits or overload conditions when used in accordance with specifications.

Suitable for

• Powering CCTV and security cameras requiring 12 V DC
• Supplying LED strips and lighting modules operating at 12 V
• Providing stable power to routers, switches and small network devices
• Running small embedded controllers, sensors and peripherals in fixed installations

Key specifications

• Output voltage: 12 V DC regulated
• Maximum output current: 6.25 A
• Output power: up to 75 W
• Input type: mains AC to switch-mode DC conversion
• Design: switching (SMPS) topology for efficient conversion
• Typical mounting: fixed installation in cabinets or panels
• Protection features: built-in overcurrent and short-circuit protection (typical for switch-mode supplies)

How to use

Install the unit in a ventilated location inside an electrical cabinet or other protected enclosure, ensuring adequate clearance around the case for airflow. Connect the mains AC input to a suitable fused supply following local wiring regulations, and connect the 12 V DC output to the load using appropriate gauge wire sized for up to 6.25 A. Verify polarity before powering connected devices. Allow the supply to run briefly without load after installation to confirm stable output voltage, then connect the devices. Do not exceed the rated current and observe manufacturer recommendations for ambient temperature and ventilation.

Usage recommendations

For reliable long-term operation, use proper fusing on the AC input, select wiring and connectors rated for the full output current, and avoid placing the supply in confined spaces without ventilation. When powering multiple devices, calculate the combined current draw to remain below the 6.25 A rating and distribute connections to avoid voltage drop on longer cable runs.
