Power Supply Unit 12V 20A (Switching) No name 12V/20A/P

The Power Supply Unit 12V 20A (Switching) No name 12V/20A/P is a compact switching power supply that delivers a regulated 12 V DC output with a maximum current of 20 A. It is intended for stabilised low-voltage power delivery to a wide range of electronic equipment, including LED strips, CCTV cameras, routers and other devices that require a reliable 12 V source. The design focuses on efficient voltage conversion and stable output suitable for both household and light industrial installations.

Advantages

This switching power supply provides a stable 12 V DC output with up to 20 A current capacity, offering reliable power for medium-demand devices. Its compact form factor allows installation in constrained spaces and integration into equipment enclosures. Built-in protective functions typically include overcurrent and short-circuit protection to help prevent damage to connected devices and the supply itself. The unit operates with the higher efficiency characteristic of switching supplies, reducing heat generation and energy losses compared with linear alternatives.

Suitable for

• Powering LED strips and lighting modules requiring 12 V DC
• Supplying CCTV and other security cameras
• Providing stable power for routers, switches and network equipment
• Feeding small audio amplifiers, control boards and embedded systems
• General-purpose 12 V power distribution in home and light industrial setups

Key specifications

• Output voltage: 12 V DC
• Maximum output current: 20 A
• Output power: up to 240 W
• Supply type: switching (SMPS)
• Typical protections: overcurrent protection and short-circuit protection (model-dependent)
• Mounting: compact enclosure suitable for surface or within-cabinet installation
• Intended use: indoor installations in household and light industrial environments

How to use

Install the power supply on a stable, ventilated surface or inside a compatible enclosure, ensuring adequate clearance for heat dissipation. Connect the AC input to a properly rated mains supply using the recommended wiring and observe local electrical codes. Verify the correct polarity of the 12 V DC output and connect the load, ensuring the combined current draw does not exceed 20 A. If the unit includes adjustment or status indicators, set the output as required and monitor the supply during initial operation. If protective features activate, remove the load and inspect connections and devices for faults before reapplying power.

Usage recommendations

Use appropriate cabling sized for currents up to 20 A and include fuses or circuit breakers in the AC and DC circuits as required by local regulations. Avoid placing the supply in unventilated enclosures or near heat sources; maintain periodic inspection for dust buildup and secure mounting. For continuous or critical loads, allow a safety margin below the maximum rated current to improve longevity and thermal performance.
