1. Multi-channel adjustable DC regulated power supply
Multi-channel adjustable DC regulated power supply is a kind of adjustable regulated power supply, which is characterized in that one power supply provides two or even three or four outputs that can independently set the voltage.
Basically, it can be regarded as a combination of several single-output power supplies, which is suitable for occasions that require multiple voltage power supplies. The more advanced multi-channel power supply also has the function of voltage tracking, so that the output of several channels can be adjusted in linkage.
2. Precision adjustable DC regulated power supply
Precision adjustable DC regulated power supply is a kind of adjustable regulated power supply, which is characterized by high resolution of voltage and current regulation, and voltage setting accuracy better than 0.01V. In order to accurately display the voltage, the current mainstream precision power supplies are indicated by a multi-digit digital meter.
The solutions of the voltage and current limiting precision adjustment mechanism are different. The low-cost solution uses two potentiometers for coarse adjustment and fine adjustment, the standard solution uses a multi-turn potentiometer, and the high-end power supply uses a digital setting controlled by a single-chip microcomputer.
3. High-resolution CNC power supply
The regulated power supply controlled by the single-chip microcomputer is also called the numerical control power supply, and it is easier to achieve precise adjustment and setting through the numerical control method. The internal circuit of the precision regulated power supply is also relatively advanced, and the voltage stability is also relatively good, and its own voltage drift is small, which is usually suitable for precision experimental occasions.
Precision DC regulated power supply is a domestic name. There is basically no nominal precision power supply for foreign imported power supplies, only high-resolution power supplies and programmable power supplies.
4. Programmable power supply
Programmable power supply is an adjustable regulated power supply digitally controlled by a single-chip microcomputer, and its set parameters can be stored for later recall. There are many parameters for programmable power supply settings, including basic voltage settings, power limit settings, overcurrent settings, and extended overvoltage settings.
