Product details
12V 10A "closed" PSU refers to an enclosed switching power supply that provides a stable 12V DC output with a maximum current of 10 Amps (120 Watts) in a secure metal or plastic case. These units are commonly used for applications such as CCTV systems, LED lighting, and industrial automation.
Specifications
Key Features
These power supplies are designed for safety and durability, often featuring a robust enclosure and built-in protection mechanisms.
Output Specifications: They provide a regulated 12V DC output with a 10A maximum current. The output voltage may be adjustable by a small range (e.g., ±10%) via a built-in trim pot.
Input Voltage: Most models support a wide AC input voltage range (e.g., 100-240V AC) for global compatibility.
Safety Features: Key protections include built-in overload protection (OLP), short-circuit protection (SCP), and over-voltage protection (OVP).
Enclosure: The "closed" or enclosed design, often made of metal or aluminum alloy, offers safety, dust resistance, and tamper resistance, making them suitable for installations in various environments.
Cooling: Cooling is typically achieved through natural air convection via vent holes, or some models may include a built-in fan for more effective heat dissipation during continuous operation.
Applications: They are widely used in commercial and residential applications, including powering CCTV cameras and DVRs, LED strip lights and sign boards, access control systems, and other industrial automation equipment
