| Application: |
Applied as pre-regulators for all types of large-scale high-grade,
precision and advanced micro-electronic systems, especially for
large fluctuations in the power grid, voltage transient leap, and
other poor power supply environments. |
| Applicable Industry: |
Widely used in the construction of base stations in the
telecommunications industry, medical equipment industry, elevator
industry, printing industry, mold and precision machine tool
processing industry, road traffic industry, and petrochemical
industry. |
| Features: |
It can effectively remove or improve the serious defects existing
in China-made Thyristor type voltage regulators such as
inefficiency, circulating current on the controlled silicon,
additional harmonics, electromagnetic interference and so on.
Integrating the non-contact switch of controlled silicon and
transformer technology, single-phase Thyristor type voltage
regulator possesses such features as small noise, large capacity,
small size, high precision, fast response, wide voltage-regulating
range, light weight, good reliability, and no waveform distortion
and so on. |
