Power AC Voltage Regulators Transformer Manual Adjustable Variable Autocoupling

Product Description

General

The voltage regulator is an autotransformer with continuously adjustable turns ratio. When the voltage regulator brushes slide along the polished surface of the coil by means of the handwheel spindle and brush holder, the turns ratio can be continuously changed. And the output voltage is smoothly adjusted from zero to the highest position.

Construction

Unit structure: 0.5KVA, 10KVA regulator is the regulator unit structure, a coil with a polished surface on the upper end surface is fixed on the base of the project, and the brush of the contact group is under the spring pressure and the coil. The polished surface is in close contact, and the rotating hand wheel drives the brush to slide on the smooth surface of the coil for voltage regulation. The unit voltage regulator is generally a table top and has a protective hood on the outside.
Single phase assembly structure: single phase large capacity voltage regulator is assembled from several units of the same specification. The brush contacts of each unit dare assembled on the same main shaft, the input ends of the coils are connected in parallel, and the output terminals are connected to the balanced reactor. To balance the current distribution between cells and suppress the circulation.
Above 10KVA is assembled by two or three or more units of the same specification.

Brush structure: 3KVA and below unit voltage regulator, using 1~2 graphite brushes and metal frame with good heat dissipation, 4KVA and above unit voltage, using two copper graphite composite brushes, brush contact group the pressure plate is fixed on the open end of the coil to limit its axial position. At the same time, it is locked with the spindle by screws. When it is necessary to dismantle and replace the main shaft or need to extend the spndle from the bottom of the regulator, it is convenient to loosen the screw.

Application:

TDGC2/TDGC2J Series regulators have the characteristics of no waveform distortion, small size, light weight, high efficiency, convenient use, reliable performance, long term operation, etc. Which achieve the purpose of voltage regulation, temperature control, dimming, power control etc. It is an ideal AC voltage regulator for chemical, metallurgical instrumentation, electromechanical manufacturing, light industry, scientific experiments, utilities, household appliances, temperature control, dimming and power control.
Ambient temperature: max. +40,min. -5
Altitude: The altitude where the regulators is installed does not exceed 1000m
Relative air humidity: the monthly average relative humidity of a wet month is 90%, and the average temperature per month is 25.
Power supply voltage waveform: the power supply voltage waveform is a sine wave or similar to a sine wave.
Installation: Indoor. The installation site is free from gases, vapors, chemical deposits, dust, dirt and other explosive and aggressive media that seriously affect the insulation of the regulator, and the installation place should be free from severe vibrations and bumps

Product Description

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.

 

Q 9. What kind of certificate you have ?

A. Our company already obtained CE , ISO9001, PCT, SGS. design and technical patents certificates.
