- Information
Product Overview
Equipped with high-efficiency single-chip microcomputer control, anti-harmonic interference, and three-phase average true RMS sampling, the regulator supports code-based digital parameter adjustment, membrane touch key operation, and a 7-inch blue-background white-character LCD display for clear, real-time monitoring.
Outperforming conventional voltage regulators, the SBW-F series features large capacity, high efficiency, independent three-phase regulation, zero waveform distortion, and smooth voltage regulation. It is fully compatible with inductive, capacitive, resistive, and non-linear loads, can withstand instantaneous overload, supports long-term continuous operation, and enables seamless manual/automatic switching. Comprehensive protection functions—including over-voltage, under-voltage, overload, over-temperature, phase loss, phase sequence, phase position, short circuit, time delay, lightning protection, and buzzer alarm—ensure safe, convenient operation and long-term reliable performance.
Built on the combination of single-chip microcomputer intelligent control and membrane switches (replacing traditional precision multi-turn potentiometer adjustment), the SBW-F series achieves fully adjustable output voltage via an intuitive man-machine dialogue interface. The upgraded KSR series adds 5-segment programmable output voltage for customized, personalized use, with optional remote operation and monitoring systems specifically developed for intelligent unmanned workshops, enabling real-time remote monitoring and convenient control.
Core Technical Advantages
1. Zero-Interruption Compensated Regulation Technology
The SBW-F series continuously compensates input voltage fluctuations in real time, ensuring critical loads receive a stable, uninterrupted power supply even during grid voltage sags, surges, or transient disturbances.
2. Stable Pure Sine Wave Output
It delivers high-quality pure sine wave output with zero waveform distortion, completely eliminating damage to sensitive equipment caused by poor power quality, harmonic interference, or voltage distortion.
3. Wide Input Voltage & Frequency Range
The system supports an ultra-wide input voltage range (±10% to ±45% adjustable) and is fully compatible with global power standards (50Hz/60Hz), making it suitable for unstable grid environments worldwide.
4. Intelligent LCD Monitoring & Remote Management
The front panel is equipped with a large 7-inch blue-background white-character LCD display for real-time parameter monitoring. It supports multiple communication protocols (RS232/RS485/SNMP/Modbus) for remote monitoring, control, and data acquisition, ideal for unmanned workshops and intelligent factories.
5. High Efficiency & Modular Design
The industrial-grade voltage regulator achieves up to 98% efficiency at full load, significantly reducing energy consumption and operating costs. Its modular design enables hot-swappable maintenance, minimizing downtime and ensuring continuous operation.
6. Comprehensive Multi-Layer Protection
The system is equipped with a complete set of built-in protection functions:
◦ Overload, short circuit and overcurrent protection
◦ Over-voltage, under-voltage and phase sequence protection
◦ Over-temperature protection
◦ Surge and lightning protection
These safeguards ensure the safety of the voltage regulator and connected loads, with reliable long-term operation.
7. Robust Industrial Design
Housed in a rugged metal enclosure with IP20/IP31 protection (customizable to IP54/IP55 for harsh environments), the system maintains optimal performance even under continuous full-load operation, vibration, and extreme industrial conditions.
8. 5-Segment Programmable Output Voltage
The upgraded KSR series adds 5-segment programmable output voltage functionality, supporting personalized and customized voltage requirements for special application scenarios.
