Introduction to those categories of regulated power supplies
A stabilized power supply is an electronic device that can provide a stable AC or DC power supply to a load.
When the grid voltage fluctuates instantaneously, the regulated power supply will compensate the voltage amplitude with a response speed of 10-30ms to stabilize it within ±2%.
In addition to the basic stable voltage function, the voltage regulator should also have overvoltage protection (more than +10% of the output voltage), undervoltage protection (less than -10% of the output voltage), phase loss protection, and short circuit overload protection. Protective function.
Classification of regulated power supply:
1. Low power linear DC power supply
Digital high-precision low-power linear DC regulated power supply High-precision adjustable DC regulated power supply is specially designed for use in laboratories, schools, factory production lines, engineering departments, and maintenance units. Its output voltage is between 0 and the nominal value. Continuously adjustable.
The stability and ripple factor of the power supply are very good, and there is a perfect overload protection circuit.
2. DC regulated power supply
ADD series switching DC power supply adopts switching power supply technology without power frequency transformer, so it has AC and DC compatible input functions, and the input voltage range is wide;
Using advanced switching power supply control technology and components, as well as careful design;
The whole machine is small in size, light in weight and high in efficiency, which ensures stable and reliable long-term full-load operation. Equipped with perfect protection function.
Built-in temperature-controlled cooling fan, which can not only effectively dissipate heat, but also effectively extend the life of the fan; overheating automatic shutdown protection; output overvoltage, overcurrent and short circuit protection.
Start-up delay soft start to avoid overshoot of output voltage at start-up.
The power supply is widely used in power DC screen system, industrial control, communication, scientific research, battery charging and other equipment.
3. Programmable DC power supply, low noise
5 groups of pre-stored voltage and current data
Automatic switching between constant voltage and constant current working states

4. Multi-line linear DC power supply
Digital high-precision multi-line linear DC power supply.
The high-precision adjustable DC power supply is specially designed for use in laboratories, schools, factory production lines, engineering departments, and maintenance units. Its output voltage is continuously adjustable from 0 to the nominal value.
The stability and ripple factor of the power supply are very good, and there is a perfect overload protection circuit.
