220V/110V Black Audio Power Purifier Isolation Transformer 4000W Audio Isolator Ring Transformer for Speakers

220V/110V Black Audio Power Purifier Isolation Transformer 4000W Audio Isolator Ring Transformer for Speakers

Features:
- Due to the stress of the iron core structure, epoxy resin can be used for odorless insulation, which is safe and environmentally friendly, and the cover of the startup box is also odorless. The ring transformer can achieve true silence, even when placed at the bedside.
- A 3000W ring transformer has a no-load current of only over 30mA, and its losses are several hundred times lower than those of an E-type transformer.
- The transformer is equipped with a soft start, which does not trip when turned on. It is standard and does not falsely indicate the power.
- There is a true primary shielding layer, with a transformer-hide double shielding. Generally, there is no shielding or half shielding for other products, and primary shielding-free or half shielding can not isolate high-frequency interference.
- The default inputs are 220V and 235V. At 220V, there is a 1:1 output, and the output voltage is the same as the input. The 235 gear is used to reduce the 12V output. Due to the high voltage of most power grids, around 235V, the 12V output is reduced, which reduces the heat of subsequent amplifiers, especially electronic tube amplifiers, and extends the lifespan of electronic tubes.
- 10 output ports in total. US standard and 220V by default.
- Built in soft start, over temperature protection, instantaneous high voltage protection, over current protection.
- All aluminum shell, fully enclosed anti-interference.
- The internal connection wires of the chassis are made of silver plated wires for Teflon, which are temperature resistant, corrosion-resistant, and have low internal resistance.
- Overcurrent protection to prevent overcurrent/overload and protect the power supply.
- Input 220V with voltage reduction function (235V input).
- Enthusiasts red copper port.
- High quality sockets (6 sockets in total, 3 sets) default to 4 United States standard sockets and 2 Chinese standard sockets.
- Independent grounding terminal (when conditions permit independent grounding, it can reduce the zero position difference of the ground wire).

FAQ:
Q: Is it necessary to use a regulated output or add a regulator?
A: In fact, electrical equipment can work normally at 10%. Generally, 10% of 220V voltage does not affect the equipment. The input of this transformer is 220V and 235V, which can be manually switched. The side effects of voltage stabilization are significant, so it is completely unnecessary to listen to music.

Q: Will it compress dynamics?
A: Some people have seriously misled this problem, because transformer manufacturers generally control the costs and reduce the wire diameter to make transformers. Most of the actual power is only one-third of the standard, and the compression dynamic is caused by large voltage drop and insufficient reserve power. Based on experience, a margin of 2 times can basically not compress the dynamic, while a margin of 3 times or more will not compress the dynamic at all, which is a completely positive improvement effect. (Please note that the speaker system power refers to the actual power consumed, not the power indicated by the body).

Q: How come the effect of using a power purifier is not significant, and is there an improvement in isolation transformer?
A: Transformers are physically separated from the power grid and can effectively purify power sources. To give a simple example, a half wave in the power grid (it can cause an increase in current for audio equipment, magnetic saturation of the iron core, and interference with the speaker's current sound, which can also easily cause the transformer's own noise.) and zero to ground voltage (which is less than 1v according to national regulations, and excessively high zero to ground voltage can cause serious interference to equipment, even causing equipment to malfunction or even damage), In terms of filtering and absorption, only isolation transformers can truly solve the problem.

Q: Why does the output display voltage? and why is it unbalance?
A: After isolation, open balanced mode, and the secondary line (after isolation, there is no zero fire. The phase is unified later) is 110V to ground, which is half of the total voltage. There is no voltage when turning off balance to ground. Using a high internal resistance voltmeter will display the induced voltage, but in reality, there is no voltage; If the correct voltage needs to be displayed, a low internal resistance meter can be used to measure the true voltage of the transformer, such as UT33D for UNI-T.
