SBW
Series Three-phase Compensated AC Power Stabilizer
SBW, SBW-F series compensated AC power voltage stabilizers (hereinafter referred to as voltage stabilizers) are
designed by our company to stabilize AC voltage by absorbing domestic new technologies and combining the
actual situation of the power grid. When the external power supply network fluctuates, it can automatically
maintain the stability of the output voltage.
Compared with other types of voltage stabilizers, this series of products has large capacity, high efficiency, no
waveform distortion, stable voltage regulation, strong control function, complete variety, wide application load,
ability to withstand instantaneous overload, long-term continuous work, manual/automatic switching at will, and
according to different use requirements, it has the options of AC/voltage-stabilized output, overvoltage,
undervoltage, overcurrent, phase sequence, mechanical failure and other automatic protection devices, as well
as small size, light weight, easy to use and install, and reliable operation.
This series of products can be widely used in large-scale electromechanical equipment, metal processing
equipment, production lines, engineering equipment, elevators and medical machinery, computer rooms,
computer control equipment, embroidery and textile equipment, air conditioners, radio and television, hotels,
household appliances and lighting in the fields of industry, agriculture, transportation, post and
telecommunications, military, railways, scientific research and culture, and all places that require voltage
stabilization.
Normal Working Conditions
1. Ambient temperature range: -15℃~+45℃;
2. Altitude not exceeding 1000m;
3. Relative humidity ≤90%;
4. The installation site should be free of gases, steam, chemical deposits, dust, dirt and other explosive
and corrosive media that seriously affect the insulation of the voltage stabilizer;
5. The installation site should be free of severe vibration or bumps;
6. Any special use conditions that do not meet the above requirements should be determined by the user and
our company through consultation.
Structural Features
The voltage stabilizer consists of a compensation transformer, a voltage regulator, a transmission mechanism, a
brush contact system, a box and a control system. The surface of the cylindrical winding of the voltage regulating
transformer is polished, the insulation is removed, and it is a smooth conductor surface to facilitate good contact
of the brush. The transmission mechanism consists of a servo motor, a sprocket and a chain.
Product features:
1. When the input power supply is missing, the voltage stabilizer can automatically detect and cut off the output.
2. The use of \"mains power direct technology\" reduces the number and capacity of AC contactors and
improves the reliability of the operation of the voltage stabilizer.
3. It has output voltage, over-voltage and under-voltage protection and alarm functions: in the voltage
stabilization state, when the input voltage exceeds the upper limit of the voltage stabilizer input (456V)
and reaches a certain value or other reasons cause the output voltage of the voltage stabilizer to be
higher than (426±8V), the output is cut off and an alarm is sounded. When the output voltage decreases,
it automatically returns to normal.
4. It has a call recovery function: when the power supply is restored after the power grid is out of power,
the voltage stabilizer has two optional functions: automatic power recovery and manual start.
5. It has a power-on delay function: in the voltage-stabilizing state, turn on the start button, and when the voltage
stabilizer adjusts itself to a stable value (a few seconds), KM3 will be energized and there will be voltage output.

The QZB series auto-step-down transformer is suitable for reducing the voltage of three-phase squirrel-cage
induction motors operating at 50 Hz, rated voltage up to 660 V, and rated output power up to 300 kW in the AC-3
utilization category under infrequent operating conditions. This transformer utilizes the transformer's step-down
characteristics to reduce the motor's starting current, thereby minimizing the impact of motor starting on the
power transmission network.
This product complies with GB/T 14048.4.
Normal Operating Conditions
1. Altitude not exceeding 2000 m
2. Ambient medium temperature not exceeding +40°C and not below -5°C
3. Relative humidity not exceeding 85%
4. The medium must be free of explosive gases and conductive dust that could corrode metals or
damage insulation.
Main Technical Parameters
Structural Characteristics
The transformer operates in a short-duty mode and is not suitable for prolonged or frequent operation.
Autovoltage transformers have two starting voltage ratio taps: 65% (60%) and 80%. The 65% (60%) tap can be
selected for lower starting torque, while the 80% tap can be selected for higher torque. This product can be
installed as a key component in the JJ1 series autovoltage transformer starting control cabinet. The starting time
for autovoltage transformers of all classes and operating modes must not exceed 15 seconds, and the number of
starting cycles per hour should be evenly distributed.
Autovoltage transformers are permitted to be started twice consecutively from a cold state, with an interval of 30
seconds.
After two rapid starts of an autovoltage transformer, the transformer should not be started again until it has
cooled to ambient air temperature.

HYIC3
Series of Intelligent Integrated Power Capacitor Compensation Devices
Application Scope
The HYIC3 series intelligent integrated power capacitor compensation device is based on two or more sets (
type) or one or more sets (Y type) of low-voltage power capacitors. It integrates advanced technologies such as
modern measurement and control, power electronics, network communications, and automated control. It
replaces traditional complete reactive power compensation devices, which consist of separate components
such as controllers, fuses, combination switches or mechanical contactors, thermal relays, low-voltage
capacitors, and indicator lights connected by wires within a cabinet.
This low-voltage reactive power compensation device features flexible compensation methods, excellent
compensation results, a compact size, low power consumption, easy installation and maintenance, a long
service life, strong protection features, and high reliability. It also offers true zero-crossing switching, meeting
users' actual needs and meeting the higher requirements of modern power grids for reactive power
compensation equipment.
Implementation standard: GB/T 15576 \"Low-voltage Complete Reactive Power Compensation Device.\"
Main Technical Parameters
Environmental Conditions:
Transport and Storage Temperature: -40°C to 70°C
Ultimate Operating Temperature: -25°C to 60°C (-40°C to 60°C available for custom products)
Relative Humidity: 20% to 90%
Altitude: ≤ 2000m (≤ 5000m for custom products)
Other Requirements: The installation site must be free of gases or conductive media that may corrode metal or
damage insulation, contain no explosive media, be free of strong vibration and shock, and
be free of severe mold.

Operating Voltage: AC 400V
Voltage Tolerance: ±30%
Operating Frequency: 50 ± 1.5Hz
Voltage Harmonics: Total Voltage Distortion Rate ≤ 5%
Network Quantity: ≤ 48 units per group
Structural Characteristics
1 Modular Structure
The intelligent capacitor features a modular design, compact size, simple wiring, and easy maintenance.
Capacity expansion only requires adding more modules.
2 Zero-Cross Switching
Core components enable “zero-cross switching,” achieving zero-voltage connection and zero-current
disconnection, reducing power loss with no inrush current, overvoltage, or arcing.
3 Protection Functions
Equipped with overvoltage, undervoltage, power loss, short-circuit, and over-temperature protection to extend
service life. Temperature protection automatically shuts down the unit when internal temperature exceeds safe
limits.
4 Control Technology
Switching is based on power factor and reactive power, using prediction and delayed multi-point sampling to
ensure stable, oscillation-free compensation, with sufficient reactive power under heavy load.
5 Intelligent Networking
Supports independent or networked operation. Faulty units automatically exit without affecting the system. Using
RS-485 communication, capacitors form an automatic network with adaptive master-slave switching for stable
operation.
