Classification of DC regulated power supply and its functional application

ZTELEC Insulation Materials | 18-10-18

A regulated power supply is an electronic device that provides a stable AC or DC power supply to the load. When the grid voltage fluctuates instantaneously, the regulated power supply compensates the voltage amplitude with a response speed of 10-30ms, which makes it stable within ±2%. In addition to the most basic stable voltage function, the regulator should have overvoltage protection (+10% of output voltage), undervoltage protection (-10% lower than output voltage), phase loss protection, short circuit overload protection. Basic protection features.

Regulated power supply classification:
1. Low power linear DC power supply
WYJ-150215V/2A digital high precision low power linear DC regulated power supply WYJ series high precision adjustable DC regulated power supply is specially designed for the use of laboratory, school, factory production line, engineering department, maintenance unit, its output voltage Continuously adjustable from 0 to nominal. 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 wide input voltage range. It adopts advanced switching power supply control technology and components, as well as careful design, the whole machine is small. Light weight and high efficiency ensure stable and reliable operation at full load for a long time. Complete protection features. Built-in temperature-controlled cooling fan can not only effectively dissipate heat, but also effectively extend the life of the fan; over-temperature automatic shutdown protection; output over-voltage, over-current and short-circuit protection. Boot delay soft start, to avoid boot output voltage overshoot. Power supplies are widely used in power DC screen systems, industrial control, communications, scientific research, battery charging and other equipment.
3. Programmable DC power supply
