Advantages And Disadvantages Of Parametric Regulators

Automatic Voltage Stabilizer is one of the fastest-growing anti-interference purification power supplies in recent years. It integrates the superior performance of isolation transformer, ultra-wide range voltage regulator, anti-interference filter, etc. It is currently the most reliable, fastest voltage adjustment speed, largest voltage regulation range, widest anti-interference frequency band, and most thorough interference protection. It can ensure that microelectronic equipment can work safely and normally in the worst power grid.

(I) Parameter voltage regulator (ferromagnetic resonance voltage regulator and voltage regulator transformer)

1. Advantages:

① High reliability (no electronic components, simple structure).

② Anti-high energy interference (good low-pass filtering effect), some manufacturers add lightning protection measures.

③ No output overvoltage phenomenon.

④ Wide input voltage range (the lower limit of input voltage can exceed 50% at half load)

⑤ Short response time (about 50ms)

⑥ Good overload performance (ferromagnetic devices have strong overload capacity).

⑦ Can be made into high-power power supply equipment.

⑧ It can be used in places with phase loss and three-phase imbalance

2. Disadvantages:

① It is heavy and consumes a lot of copper and iron materials, so the price is relatively high.

② The consistency of mass production is poor (affected by the core material and process).

③ The source power factor is low and the efficiency is also low.

④ The temperature rises and the noise is large.

3. Applicable occasions

Departments with special requirements for reliability and anti-interference performance, such as defense units, banks, tunnels, highways, remote parameters, etc.
