Product Details
SCWY series three-phase AC parameter stabilized power supply
● Product Overview
SCWY-III seriesthreeThe cross current parameter stabilized power supply is a power supply device that uses the principle of ferromagnetic equivalent parameter oscillation and synchronous tracking compensation to achieve stable AC output voltage and good bidirectional anti-interference performance. The major structural feature is the absence of electronic equipment, high environmental adaptability, and stable and reliable performance.
● Main features
1. Wide voltage regulation range and high output accuracy: output voltage of 380 ± 1-5%; The working range of input voltage can reach 380V ± 20% (customizable wide range).
2. Extremely short response time and unique excellent dynamic characteristics. It can be restored in 10-40ms, which is several tens of times faster than mechanical adjustment regulators.
3. Anti lightning strike, anti surge, wideband suppression of interference
The anti-interference frequency band is wide (200HZ-2MHz), and the amplitude effect can be considered the first. Low pass filters for other power sources typically have a low-end cutoff frequency above 100KHZ, with only a few able to achieve 10KHz
Constant mode interference suppression greater than 50DB
Differential mode interference suppression greater than 200:1
The lightning resistance capability can reach 6000VPP (10 μ s/700 μ s)
The anti surge capability can suppress the surge voltage of 5KHZ at the input end up to 2000V without affecting the operation of electrical equipment.
4. Improve waveform distortion, even if the input waveform distortion reaches 30%, the output voltage waveform distortion can still be maintained below 2.5%.
5. The three-phase output phase and line voltage balance is excellent, allowing for a three-phase voltage imbalance of up to 50% and a current imbalance of up to 50%.
6. Phase loss protection function: With a unique three-phase magnetic flux balance circuit design, it can maintain normal three-phase voltage output even in the absence of phase, providing operational protection for equipment (below 30KVA). There is a fundamental difference in the design of circuits for phase loss alarm and mechanical tripping and power-off.
7. Wide load adaptability, strong overload capacity, and unique output load short-circuit self-protection function. When the output terminal is short circuited, the output voltage automatically drops to zero due to changes in magnetic flux distribution in the magnetic circuit, entering a protective state. At the same time, the input current is also limited, which does not affect the operation of the power supply line, effectively protecting the load and preventing disasters from occurring. There is a fundamental difference between mechanical tripping and traditional circuit breakers.
Extremely reliable: no mechanical adjustment device, simple structure, reliable operation, can be regarded as semi permanent equipment
