Ac power supply is the main power supply mode in the power system. With the improvement of industrial automation level and the development of computer, communication and other equipment, the requirement of AC power supply is becoming higher and higher.
High power programmable Direct current (DAC) is a device that converts power frequency mains into direct current. It has the characteristics of small size, light weight, high efficiency, high reliability and long service life.
DAC is a device that converts power frequency mains into direct current. When the input AC voltage reaches a certain value, the output end produces a pulse voltage proportional to the input current; When the input AC voltage drops to a set value, the output pulse amplitude decreases to zero and becomes a low amplitude or zero amplitude output; When the input AC voltage rises to a set value, the output pulse amplitude increases to the maximum and becomes a high amplitude or full amplitude output; In the above process, if the load power factor is greater than 1, the load current remains stable. On the contrary, it changes with the output power.
It can be divided into general-purpose DAC and high-power DAC according to its use:
(1) General purpose Dac: General-purpose DAC is a high-power switching circuit composed of single-phase rectifiers. This structure is relatively simple. Suitable for general use.
(2) High power D ac: High-power dac A high-power switching circuit consisting of three-phase rectifiers. The structure of this class is complex. But good performance. Can be used for transformer control protection circuit.
Widely used in all kinds of electronic equipment drive and protection of DC-DC conversion circuit and as other electronic equipment such as frequency converter power supply. Because of its powerful function and good characteristics, it has become one of the important equipment in many fields.
Class A is a high power modular modular design with an all-aluminum shell design. Built-in high performance chip, internal integrated PWM signal processing circuit. With a variety of interface forms to choose from. Class B is a standard rack-mounted design with an all-aluminum housing design.
