Introduction:
Purified alternative parameter regulated power supply adopts the principle of sine energy allocation and is one cf the most popular regulated power supplies at present throughout the world. control unit makes quick snd accurate response according to the input voltage snd the changes of output load, adjusts promptly the compensated voltage of sine energy allotter so as to control efficiently the output voltage, So the whole machine has high accuracy and good dynamic performance equipped with big-capacity wave filer inhabiting effectively higher harmonics, peak voltage, signal of noise interference in the input electric network and making waveform more pure.it joints stabilivolt, purification, anti-interference snd auto-protection, so becomes one of the advanced regulated power supplies at present, this series can be widely used in the places such as computer-related products, medical control monitor system, progrsm controlsystem, auto matictesting eguipment, broadcast television equipment, telecommunication equipment, production line, printing equipment, plastic injecting equipment, sutomatic teller machine, SMT equipment, research and experiment.
Features:
1 .Autidistrubance common mode noise rejection
50dB, Output sine wave with distortion 3.5% even for
input square or complicated wave ( See Fig 1,2)
2. Harmonic suppress: 3rd～7 th harmonic
can be well suppressed, eliminating 3 rd harmonic up to
90%
3 .There is no galvanic connection
between input and output. The output neutral line can be
direct grounded to earth
4 .There is only two high reliability
component – Transformer and condenser in the set. TJA/CVT
has high reliability.
5 .If over load or load short circuit
occurs, the output voltage will collapse, and the
current be limited to approx 150 or 250% of max rated.
There is no damage in the regulator. As mistake has
eliminated, the unit auto-recover.
