The SF120H200 is a switch-mode power supply used in a variety of applications including landscape lighting, CCTV systems, and medical equipment. It provides a constant voltage power source with little to no ripple, and can be used with a wide range of input voltages from 90VAC to 264VAC.

The SF120H200 is based on a full-bridge rectification circuit, which consists of four diodes and a pair of switches. The circuit works by alternately charging and discharging a high-frequency gate, causing the switches to open and close in rapid succession. This produces alternating current (AC) on the primary side of the transformer, which is then rectified and filtered to produce the desired output voltage and current.

The switch-mode power supply can be used in a variety of applications requiring different levels of power. For example, it can be used to supply power to small lighting systems in landscapes and parks, and to power larger lighting systems for stadiums and arenas. It is also used to power video surveillance systems, medical equipment, and many other electronic devices.

The SF120H200 is a cost-effective solution for providing stable power in many applications. It is designed to be low cost, reliable, and simple to use. It has a built-in EMI filter, over voltage protection, and over-temperature protection, making it suitable for a wide variety of applications.

The SF120H200 is a compact, lightweight, and efficient switch-mode power supply, making it an ideal choice for many applications. It can be used with a wide range of input voltages, and can deliver a stable voltage and current, making it suitable for many different types of devices.
