2. Features:
- Oil-immersed Induction type, Motor controlled system
- Stepless voltage adjustment (brushless):
-
With inductive and contactless voltage regulation, the voltage stabilizer can increase and decrease the load voltage linearly.
- Excellent features: By using high-magnetic-inductivity silicon steel sheet made in Japan, this voltage stabilizer minimizes the no-load loss and no-load current, and with its performance utilized best, reduces power loss.
- Robust, durable and long life expectancy: The internal body of this voltage stabilizer is induction voltage regulator IVR, containing no carbon brush and its main characteristics are permanent wear-proof, robust and long service life.
- High efficiency, and low power consumption: High efficiency: >98% & Low power consumption<1%
- Large capacity & high efficiency
- Stable voltage adjustment
- Applied for arbitrary loads
- Continuous heavy duty
- Durable service & Long life
- Low consumption
- Low wave distortion(<3%)

- Large electromechanical devices in industry, agriculture, communication, post and telecommunication, military, railway, science research etc.
4. General:
TNSJA series the 2nd generation industrial-grade Oil-immersed Induction(Brushless/Stepless) Voltage Stabilizer is composed of voltage regulator and transformer SSTS (including, oil tank, stator, rotor top Cover, drive control motor M, hand wheel, control circuit board and secondary circuit elements for voltage regulation control. It achieves the rotational voltage regulation through electric motor drive or hand wheel and gear coupling within the rotation range of 180. Besides, it is provided with the electric SS limit and mechanical limit on the upper end of the oil tank. For electric SS limit, the power supply of motor is switched off by a limit switch and for the mechanical limit, the rotational limit is stopped by bolt protector. The stator winding and rotor winding are fixed by the base frame and put into the oil tank with 10 # transformer oil. When the load generates heat, the heat dissipates from the radiating pipe by the way of Oil-immersed cooling. The oil immersed voltage stabilizer has the functions of phase failure, phase loss, overvoltage and over-current protections, and its main circuit has the characteristics of contactless voltage regulation, no mechanical wearing, no spark, no interference and low failure rate. In addition, this voltage stabilizer has the advantages of high impact resistance, super strong instantaneous overload capacity, long service life and maintenance free.
5. Work principle:
The structure of the Voltage Regulator is similar to the general wire-wound asynchronous motor, but because it often works under the braking state, its action principle is actually similar to the transformer action principle. The Voltage Regulator is equipped with a worm gear drive mechanism to cause angular displacement of the rotor. Or make the rotor brake. When the relative Angle position of rotor is changed, the alternating chain flux between stator winding and rotor winding is changed for single-phase Voltage Regulator. For the three-phase Voltage Regulator, the induction potential phase on the stator winding and rotor winding is changed, and the output voltage is also smoothed and stepless by coupling the circuit.
6. Product workmanship:
With high mechanization equipments, the products will be more beautiful, compact and good heat dissipation. The automatic production process will be more efficient, lower labor cost, and increase production capacity, further to improve the overall performance of our products and production workmanship level.
7. After-sale services:
CONPO manufacturer guarantees free maintenance(except unsuitable operation) within one year after the date of Bill of Lading(B/L). After guarantee period, we provide free technical service and collect charges for damaged material, please contact our service department for any special condition.
8. Notes for ordering:
Please notify the model product, capacity, input voltage range and output voltage, accuracy as well as the application environment(normal product if no special requirements) when ordering.
