TNSJA series oil immersed induction contactless voltage regulatorDetailed product description：

The TNSJA series oil immersed induction contactless voltage regulator consists of a regulating transformer TS (including oil tank, stator, rotor cover, transmission control motor M, handwheel mechanism, and control circuit board regulating control secondary circuit components). Through the coupling of electric motors or handwheel mechanisms and gears, the rotational voltage regulation is achieved within a range of 180 º. Electrical and mechanical limits are installed on the upper end of the fuel tank, with the electrical limit being cut off by a travel switch to cut off the power supply to the motor, and the mechanical limit being blocked by protective bolts to block its rotational limit. The stator winding and rotor winding are fixed by a bottom bracket and placed in an oil tank containing 10 # transformer oil. When heat is generated by the load, it is cooled by oil immersion and dissipated through heat dissipation pipes. Equipped with phase mismatch, phase loss, overpressure, and overcurrent protection; The main circuit has the characteristics of non-contact adjustment, no mechanical wear, no spark generation, no interference effect, and low failure rate; Moreover, it has the advantages of strong impact resistance, extremely strong instantaneous overload capacity, long service life, and no maintenance required.

TNSJA series oil immersed induction contactless voltage regulator features:
1. Accurate output voltage
The control board adopts precision logic circuits and precision components, which can output the most accurate voltage in harsh environments, with an accuracy of 380V ± (1-3%) and can be freely set.
2. Stepless voltage adjustment (brushless)
Inductive and contactless, with linear boost and buck adjustment at the load voltage.
3. Excellent characteristics
Using Japanese made high magnetic silicon steel sheets, the no-load loss and no-load current are minimized. Maximize the performance of the voltage regulator and reduce power loss.
4. Excessive capacity and strong overload capability
This voltage regulator can withstand 100% load and can be used continuously, allowing 2-3 times the instantaneous current to pass through without damaging the device.
5. Durable and sturdy, with a long service life
The internal main body is the inductive voltage regulator IVR, which has no carbon brushes or other contactors and components, and is characterized by never wearing out and being sturdy and durable.
6. Easy to maintain and upkeep
Adopting modular design, all components have been standardized. Just keep the interior clean without any special maintenance.
7. Suitable for ultra large capacity
Inductive single machine can be used for models with a capacity of over 1600KVA.
