Products Description
TND Series single-phase high precision automatic AC voltage regulator is composed of contact type auto-coupling voltage
regulator, servo motor and automatic control circuit. When the grid voltage is unstable for the load changes, the automatic
sampling control circuit sends a signal to drive the servo. The motor adjusts the position of the auto-coupler carbon brush to
adjust the output voltage to the rated value and reach a steady state.TND3 series high-precision AC voltage regulator has the function of direct power supply. It has many advantages such variety,
fully specifications and beautiful appearance. It has the advantages of no waveform distortion, high efficiency, reliable
performance, long-term operation, etc. It has short delay, overvoltage and other protection functions. It can add long delay and
undervoltage protection according to the needs of users. The product can be widely used in any place of electricity, it is an
ideal regulated power supply to ensure the normal operation of your electrical equipment. Suitable for office equipment, test
equipment, medical equipment, industrial automatic equipment, household appliances, lighting systems, communication system, etc.

Q 1. What’s the payment term?
A. We accept TT,30% deposit and 70% balance against copy of BL.
Q 2. How’s the delivery time ?
A.Usually it will take about 7-20 days for production. For sample usually in 1 week.
Q 3. Tell me the standard of package?
A. For the small capacity, color box as inner package and carton as delivery package. For big capacity, use strong wooden case for protection.
Q 4. What kind of material of stabilizer?
A. For servo type stabilizer, we have two types, one 100% copper and the other is copper with aluminum. It depends on your requirement . In fact, those two have no difference if normal work well. Only except the long life. Copper is better and also higher price. For relay type stabilizer, we use toroidal coils, the material is aluminum. comparing with square coils, toroidal coils with high efficiency.
Q 5.Could you offer Form A or C/O ?
A. It’s totally not a problem. We can prepare relative documents to foreign affairs office or other offices to apply for this certificate.
Q 6.Would you accept to use our logo ?
A.Our logo is ZX. If your order, has good quantity, it’s absolutely no problem to do OEM. But if you use our logo ZX, it will be high appreciated.
Q 7.We want to know month capacity.
A. It depends on which model. For example for relay type small capacity , month capacity can reach near 10000pcs and big capacity near 2000pcs.
Q 8.Where is your market?
A. Our products are popular in North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, Mid
East, Eastern Asia, Western Europe and so on. Some of them are our regular customers and some of them are developing. We hope you can join us and make mutual benefits from our cooperation.
