Introduction of [DC aging power supply]

61KD series DC-stabilized power supply is a voltage-stabilized and current-stabilized switching power supply. It adopts advanced high-frequency pulse width modulation (PWM) technology and adjusts the pulse width of the conversion circuit to achieve voltage stabilization and current stabilization. This power supply has high stability, low ripple voltage, long continuous time, and automatic protection functions such as over-voltage, over-current, overheating, over-temperature, etc., so that the output voltage and current can be kept reliable and stable under any circumstances. The whole system is controlled by Atmel high performance 8-bit AVR single chip microcomputer (ATmega162), which is measured by two-channel A / D conversion module and controlled by two-way D-A conversion module. All the parameters and the working state of the instrument are displayed and set on the 7-inch color touch screen (MT6071I) in Taiwan. All kinds of parameters are cut off and memory, and the user-friendly interface is easy to operate. The power supply also has a network-controlled RJ45 communication interface.

Maintenance and regular maintenance of [DC aging power supply]

Maintenance:

To prevent the occurrence of electric shock, do not lift the cover of the instrument. All parts inside the instrument need not be maintained by the user. If there is an abnormal condition in the instrument, please ask for maintenance from my laboratory. the attached lines and block diagrams are for reference only.

Regular maintenance:

At least once a year, the AC power supply and relevant accessories of input power line shall be carefully checked and checked to protect the safety of the user and the accuracy of the instrument.
