No contact, no carbon brush

The main circuit adopts several combinations of compensator transformers，it switches zero voltage of relay and thyristor to realize the voltage stabilization. It totally has avoided the flows such as hi-frequency distortion caused by the sparkle abrasion and touch of the carbon brush produce. It has long work life. Its MTBF can reach above 100,000 hours.

The voltage-regulating system

Simple construction. The whole machine has no drive system such as motors, chains and gears.

The remote monitor (optional)

We design monitor interface and realize remote communication, remote measurement and remote control, according to the communication protocol of Directorate General of Telecommunications, The Information Industrial Department.

The lightning and surge protector (optional)

The stabilizer is equipped with surge protector. The lightning and surge protector and lightning module of the first brand in world, American JOSLYN, is optional.

The power factor compensation system (optional)

The users who has big inductive load should be equipped with automatic power factor compensation system. After compensation, the power factor can reach above 90%.

The main circuit filtering system (optional)

The main circuit can be equipped with the PD series type filter according to the need of customers.

5. 5B type contactless stabilizer’s advantages

(1) The extremely fast regulation, it just needs 40 milliseconds to output stable voltage (the machinery carbon brush type needs 7 second to complete the regulation).

(2) The regulation without carbon brush touch and machinery operation (80% faults of the carbon brush stabilizer are resulted in by the machinery drive and carbon brush)

(3) The three phase separate regulation and the adaptation to the three phase unbalance load (Other stabilizers adopt the collaborative regulation. they have to raise the fee to adopt separate regulation).

(4)According to the grid condition, the highest compensation can reach ±50% (the highest compensation of other stabilizers just reach ±30%).

(5)The effect of energy-saving is obvious and the efficiency can reach 99% (the efficiency of other stabilizers is below 95%).

(6)When our product works under the low voltage, it can guarantee the load capacity 100% (the load adaptation of parameter stabilizer is bad, it can’t adapt to nonlinear device).

(7)Our product can adapts to the any work environment of bad and high safety request (Oil-immersed stabilizer leaks oil easily, so it can’t adapt to the occasion above)

(8)Our product can depress the surge and absorb harmonic waves with the lightning and filtering function (Magnetic-compensation stabilizer results in the harmonic waves when it works).
