Introduction to the categories of Epps regulated power supply
A regulated power supply is an electronic device that can provide stable AC or DC power to a load.
When there is an instantaneous fluctuation in the grid voltage, the stabilized power supply will compensate for the voltage amplitude at a response speed of 10-30ms, making it stable within ± 2%.
In addition to its basic voltage stability function, the voltage regulator should also have basic protection functions such as overvoltage protection (over+10% of output voltage), undervoltage protection (below -10% of output voltage), phase loss protection, and short-circuit overload protection.
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 continuously adjustable from 0 to the nominal value.
The stability and ripple coefficient of the power supply are very good, and there is a complete overload protection circuit.
2. DC stabilized power supply
The ADD series switching DC power supply adopts the switching power supply technology without power frequency transformer, which has AC and DC compatible input functions and a wide input voltage range;
Adopting advanced switch power control technology and components, as well as meticulous design;
The entire machine has small size, light weight, and high efficiency, ensuring stable and reliable long-term full load operation. Equipped with comprehensive protection functions.
