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 function of stabilizing the voltage, the voltage regulator should also have overvoltage protection (over +10% of the output voltage), undervoltage protection (below -10% of the output voltage), phase loss protection, and short-circuit overload protection. Protective function.
Epps regulated power supply classification:
1. Low power linear DC power supply
Digital high-precision low-power linear DC regulated power supply The 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 function, and the input voltage range is wide;
