AC DC Converters

The VCS70US15 AC/DC Converter is a power converter specifically designed for applications where an unregulated AC input is required. It is capable of providing a clean, regulated output of up to 70W of power. The versatile converter is suitable for all types of AC power input sources, such as computers, PLCs, and other industrial applications. The VCS70US15 is able to accommodate most AC line frequencies and features AC and DC circuit protection.

Features of VCS70US15

• Wide input voltage range of 90 to 270V AC worldwide.
• Regulated output voltage ranging from 5V to 24V DC.
• AC/DC line protection from over voltage, short circuits.
• Small size and light weight.
• Multiple-input capacitors for higher grade noise suppression.
• Thermal protection.
• UL/CSA/TUV recognized.

Working Principle

The VCS70US15 uses a switching architecture based on a wideband GaN transistor as the main active switch. A low EMI voltage mode control circuit provides high power factor, low standby power consumption and reduced EMI/RFI noise. It also features a high-speed Valley Seam Width Modulation (VSWM) technique for regulating the output voltage. When the voltage exceeds the set level, the circuit quickly switches off the power, protecting the load from over voltage and over current conditions.

The VCS70US15 has comprehensive protection functions. It features input over voltage and over current protection to protect the system from input power failure. The output over voltage protection and output short circuit protection feature cuts the output power if the set voltage is surpassed or the output is short circuited. It also features thermal protection that adjusts the output power based on the converter temperature.

Application Field

The VCS70US15 AC/DC Converter is ideal for any application that requires a wide range of input and output power. It is widely used in industrial control, automation equipment, building automation and LED lighting industries. Typical applications include programmable logic controllers (PLCs), distributed control systems (DCSs), inverter controllers, LED lighting, motion control systems and 3-phase AC motor drives.

The VCS70US15 AC/DC Converter is also widely used in consumer electronic products such as media players, digital tuners and CD players. In addition, it is used in office automation equipment, such as automated teller machines (ATMs), scanners, computers and printers.

Conclusion

The VCS70US15 AC/DC Converter is a versatile, easy-to-use power supply designed for a wide range of applications. Its wide input voltage range and multiple output protection features provide reliable performance and safety for industrial applications. Its small size and light weight make it ideal for consumer electronics and office automation products.
