BHA POWER GUARD SQ-300 Automatic Voltage Regulator – Power Guard Series
When voltage fluctuations strike an industrial facility without warning, the consequences cascade fast: CNC machines misfire, PLC controllers reset unexpectedly, servo drives trip on overvoltage faults, and entire production lines grind to a halt. Unregulated power doesn’t just cause downtime — it silently degrades sensitive electronic components, shortens equipment lifespan, and exposes operations to costly unplanned maintenance. The BHA POWER GUARD SQ-300 exists precisely to prevent this scenario, delivering rock-solid voltage stabilization that keeps your automation systems running at peak performance regardless of grid instability.
Within BHA’s Power Guard Series, the SQ-300 occupies a critical mid-range position — engineered for facilities that demand more than basic surge protection but require a compact, cost-effective solution without the footprint of large industrial UPS systems. BHA (Bao Heng An) has established itself as a trusted name in power conditioning across Southeast Asia and emerging industrial markets, with the Power Guard SQ-300 widely deployed in manufacturing plants, data centers, and process automation environments where power quality is non-negotiable.

Frequently Asked Questions
Q: What is the difference between the BHA POWER GUARD SQ-300 and a standard surge protector?
A: A surge protector only clamps transient overvoltage spikes. The POWER GUARD SQ-300 is an Automatic Voltage Regulator (AVR) that continuously corrects both over-voltage and under-voltage conditions, providing sustained power quality management rather than one-time spike suppression.
Q: Is the BHA POWER GUARD SQ-300 suitable for three-phase systems?
A: The SQ-300 is designed for single-phase applications. For three-phase power conditioning requirements, please contact us to discuss alternative BHA models or compatible solutions.
Q: Can I use this AVR with a PLC control panel?
A: Yes. The POWER GUARD SQ-300 is commonly installed as the primary power conditioning stage feeding PLC power supply modules, HMI panels, and I/O racks to ensure stable 220V AC input.
Q: What is the lead time for international orders?
A: Standard lead time is 3–7 business days for in-stock units. Express shipping options are available. Contact us for your specific destination and urgency requirements.
Q: Do you provide a warranty on BHA products?
A: Yes. All products sold through Konmask.com carry a quality guarantee. Please refer to our warranty policy page or contact support for specific terms applicable to this model.
Q: Can I request a datasheet or technical manual before purchasing?
A: Absolutely. Email support@konmask.com with the model number and we will provide available technical documentation promptly.
