AC DC converters are electrical devices that are capable of converting energy between alternating current (AC) and direct current (DC). The VF-D320-D512A-1 is a DC-AC power converter with wide range operating voltage, long life, high-efficiency, and low cost. It is suitable for a variety of applications such as distributed power systems, UPS, television and networking systems, solar energy systems, and telecom markets.

VF-D320-D512A-1 is an off-line just-in-time AC-to-DC converter. It has four outputs, with an output voltage range adjustable to meet the requirements of different applications. It has very fast over current protection, with a 3V out to 2A peak current capability. It also features an over-voltage protection function and short circuit protection, which can help ensure device safety. It adopts a comprehensive automatic protection and recovery system technology, quick start, high working efficiency, and a built-in high-speed power Boost. It is also designed to provide reliable operation in high-reliability and long-term mission-critical applications.

The VF-D320-D512A-1 operates on a flyback topology using an error amplifier to monitor the output voltage from a remote sense. A primary side MOSFET is regulated by a feedback loop to provide constant output power. There is an internal PFC (power factor correction) function to correct the input current and provide smooth and steady output current. This converter also features built-in power good signal and over-voltage protection (OVP) for each output, ensuring the device is running safely and efficiently under all conditions.

The VF-D320-D512A-1 achieves a high efficiency of up to 96%, and a no-load power of up to 0.2 W across the operating frequency range (60 Hz to 50 kHz). The high efficiency, wide input voltage range (85 VAC to 265 VAC), and low standby power make it well suited for energy-saving applications. The high reliability of the device is enabled by the use of high quality components including a low ESR input capacitor and over-temperature protection.

The VF-D320-D512A-1 is suitable for stand-alone or distributed AC power supplies. It is also ideal for applications such as telecommunications, industrial and medical instrumentation, broadcasting and entertainment equipment, and solar energy systems. Due to its low noise performance and long operating life, it is a great choice for long-term, mission-critical applications.
