Desktop power supply 120W 12V 8.5A GST120A12-R7B

Universal desktop power supply for wide applications

The Mean Well GST120A12-R7B desktop power supply is a solid and efficient power source, ideal for both professional installers and end users. The device provides stable 12V DC with a maximum current of 8.5A and a power of 102W, making it a universal solution for powering various electronic devices – from simple receivers to more demanding systems.

Key features and applications

The power supply is characterized by a wide input voltage range (85-264V AC), making it compatible with most electrical networks. The design based on an active PFC (Power Factor Correction) filter improves energy efficiency and minimizes interference in the power grid. The housing made of flame-retardant plastic (94V-0) ensures safety of use, and the built-in protections protect both the power supply and the devices connected to it against short circuits, overloads, overvoltages and overheating. This makes it suitable for applications requiring reliability and safety.

It will find application in:

• powering monitoring systems,
• LED lighting,
• home automation devices,
• powering audio-video equipment,
• industrial applications.

Efficiency and compliance with standards

The GST120A12-R7B power supply meets the requirements of Energy efficiency Level VI energy efficiency standards and has safety certificates such as UL62368-1, TUV BS EN/EN62368-1 and others (details in the technical documentation). Efficiency at the level of 88.5% translates to lower energy consumption and less heat loss. An LED indicator informs about the operating status of the device. The IEC C14 input connector makes it easy to connect to the network, and the output terminated with a Ø2.5xØ5.5x11mm plug ensures compatibility with popular devices. The operating temperature in the range of -30°C to +70°C allows the power supply to be used in harsh environmental conditions.
