AC/DC converters are electronic devices that can convert alternating current (AC) power into direct current (DC) power. They are widely used in a variety of applications, including industrial, lighting, medical, audio, and automotive markets. The VMS-275-58 is a high-performance AC/DC converter designed specifically for applications such as lighting, motor drive, and energy storage systems.

The VMS-275-58 has a wide input voltage range of 90-275VAC and a wide output power range of 0-55 watts. The built-in maximum power point tracking (MPPT) technology enables the converter to automatically detect and track the maximum power point of the input waveform, ensuring a high efficiency output of up to 95%. The converter also features a built-in active power factor correction (PFC) function to reduce harmonic distortion and harmonic current in critical applications.

The VMS-275-58 is equipped with comprehensive protections such as overvoltage, overload, over temperature and short circuit protection. The converter is able to withstand high surge current up to a 6-times of its rated short-time overload current, making it even more robust and reliable. It also features a wide operating temperature range of -40 to +85°C., making it suitable for various outdoor application.

The output of the VMS-275-58 can be adjustable up to two channels. It supports +/-10% output voltage adjustment through a single external resistor. The output can also be synchronized with an external signal (0-100 Hz) for powering sensitive loads, such as LED lightings. Furthermore, it also supports dimming modes such as 0-10 V, PWM and 10V PWM dimming with third-party dimmers.

The VMS-275-58 is a series of high-performance AC/DC converters designed to meet the needs of lighting, motor drive, and energy storage systems. It offers high efficiency, active PFC, wide input voltage and output power range, comprehensive protection, and adjustable output. With its wide range of features and superior performance, the VMS-275-58 is an ideal choice for applications that require reliable and efficient AC/DC conversion.
