AC/ DC converters are widely used in many industries for a variety of applications, including data processing, home appliances, industrial machines and robotics. RAC30-15SA is a three-phase AC/DC converter with a efficiency rating of over 95%. Its high efficiency combined with its very low harmonic distortion and its wide operating temperature range makes it highly suitable for many applications.

The RAC30-15SA has a total power output of 30 kW and an input voltage of 380–420 Vac or 480–520 Vac. It features a high power factor of over 0.95, mainly due to its power factor correction circuit and its high input current ripple. It has an adjustable output voltage and a wide frequency range of 20–105 Hz, which makes it suitable for varying operating conditions. The RAC30-15SA also includes a built-in current limiting circuitry and an EMI filter which provides extra protection against high voltage spikes from the power grid.

The RAC30-15SA works on a Pulse Width Modulation (PWM) control method to control the output voltage. The output voltage is determined by the Pulse Width Modulated (PWM) analog signal from the control circuit. The PWM signal is generated by an advanced digital signal processing (DSP) based microcontroller. This advanced DSP enables fast and precise control of the output voltage and also provides an adjustable duty cycle for better control of the load. The PWM control method is also responsible for providing soft start and active power factor correction to maintain a higher power factor at the input.

The internal power components of the RAC30-15SA are designed to operate in harsh conditions. The converter is built with three sets of power electronics devices including SCRs, IGBTs, and MOSFETs. These devices provide a high power output for high performance applications. The RAC30-15SA is also equipped with an advanced current limiting circuit which provides extra protection against over-current and under-current conditions. The internal cooling system ensures the power devices are cooled efficiently and can withstand long operating hours without any problems.

The RAC30-15SA is designed to operate in a wide range of temperatures. The operating temperature range for the converter is -20°C to 70°C, which is suitable for most industrial applications. The converter also includes various protection features such as input under voltage, output overvoltage, output short-circuit, and input overcurrent protection. It also offers various communication interfaces for remote monitoring and control.

The RAC30-15SA is a highly efficient and reliable AC/DC converter for many industrial applications. It features a power output of 30 kW, a wide operating temperature range of -20°C to 70°C, and a high power efficiency of over 95%. It offers adjustable output voltage, PWM control, soft start, current limiting circuitry, EMI filter, communication interface, and various protection features. All these features make it highly suitable for industrial applications where reliability and performance are of utmost importance.
