SJW, DJW series microcomputer no-touch control stabilizer is widely used for the electric equipments in industry, agriculture, transportation, post office, and military and so on. It is
also applied to metal processing device, production line, building implements, medicare facilities and household appliances etc. CHARACTERISTICS
1) Quick response It is controlled by single machine. The sampled voltage is transferred to digital signal by A/D transfer circuit and then directly to single machine. After the
disposal of the single machine and controlling the regulating mode, the voltage regulator gets quick response (0.1-0.2s, it is 1/10 of the common regulator of servo-motor carbon
2) Automatic operation, high reliability. It not only has auto start function but also has the bypass system. When the regulating system of the device cannot work well, the voltage
regulator will automatically switch to direct city power to supply the load two minutes later.
3) Complete protection function: self-diagnosis and self-recovery. It has protection functions on over-voltage, lack-voltage, over-current (short circuit), lack phase, malfunction
etc. to ensure the regulator and load in good order. If the above mentioned situations take place, it will self-diagnose the situation, automatically cut down the output power and
give sound and light warning signals. Once the over-voltage or lack voltage returns to normal, the machine will recover to output stabilization after 1 minute's automatic time delay.
4) High efficiency The use of imported wires of high magnetic ratio and stalloy with low loss makes no-load loss and the load loss to the minimum. The efficiency of the full load is
higher than 97%.
5) Wide range The input voltage range is 20%. The adjustable range of the output voltage is +5%. The input voltage range can get to Un 40% according to the customers''
requirements. It can be applied to the places where the power net is not good.
6) Proper regulating precision When the regulating range is 20%, the precision is 3%, which can meet the voltage requirements of the load.
7) It adapts to the different load such as resistance, sensibility and inclusiveness. The absolute value of the capacity factor is more than 0.7 and the device can work continuously
for a long time.
8) The input and output voltage is at the same phase position, which cannot make waveform distortion.
9) It can be assembled with RS232 connector to realize remote control
