10-200KVA 380V Modular Online UPS

BKH Series Modular Online UPS Power Supply – High-Efficiency, Reliable, and Scalable Uninterruptible Power Solution

The BKH Series Modular Online UPS is a cutting-edge power protection system engineered for enterprise-grade performance, combining energy efficiency, modularity, and intelligent control. Designed by Baykee, this advanced uninterruptible power supply delivers up to 96% operational efficiency while maintaining strict compliance with international standards for power quality and sustainability. Ideal for data centers, industrial automation, healthcare facilities, and commercial infrastructure, the BKH series ensures continuous uptime even during grid fluctuations or outages.

Key Features:

This Modular UPS system leverages N+X redundancy architecture, enabling hot-swappable power modules ranging from 10kVA to 50kVA each. A single cabinet supports up to 200kVA, and multiple cabinets can be seamlessly combined for capacities reaching 400kVA—offering unmatched scalability without compromising reliability. With dual DSP (Digital Signal Processor) and dual CPLD (Complex Programmable Logic Device) controllers, the system eliminates single points of failure, ensuring stable operation under heavy load conditions. Its digital control over rectification, inversion, battery charging, and discharging guarantees precise voltage regulation and enhanced waveform purity.

The BKH Series features an integrated IGBT-based inverter design that boosts thermal efficiency and reduces harmonic distortion below 3% (THDi), meeting stringent power quality requirements in sensitive environments. The inclusion of both lead-acid and Lifepo4 Battery management systems allows flexible deployment based on site-specific needs, while optional battery banks—available in either 48V LiFePO4 or 12V lead-acid configurations—offer extended runtime and long-term cost savings. An intelligent fan system adjusts speed dynamically, minimizing noise and reducing energy consumption—a crucial advantage in server rooms and office buildings alike.

User-friendly interfaces include an LCD + LED touch screen display, simplifying diagnostics, maintenance, and real-time monitoring. All circuit boards undergo three-proofing treatment (moisture, dust, and corrosion resistance), making it suitable for harsh industrial settings. Additionally, DC cold start capability enables immediate operation without external AC power, ideal for emergency scenarios or remote installations. Parallel connection via dedicated parallel cards ensures seamless multi-unit synchronization, further enhancing system flexibility and fault tolerance.

Common Use Cases:

This robust modular online UPS is widely adopted across industries requiring uninterrupted power delivery—from IT infrastructure and telecommunications to manufacturing plants and medical imaging equipment. Whether deployed as a standalone unit or integrated into a larger power architecture, the BKH Series excels in applications demanding high availability, low total cost of ownership, and future-proof scalability. It’s particularly effective in environments where power stability directly impacts productivity, safety, or regulatory compliance.

Customer Feedback:

Users consistently praise the BKH Series for its intuitive interface, exceptional reliability during power disturbances, and ease of expansion. Many highlight how the modular design significantly reduced downtime during maintenance and improved overall system resilience compared to traditional monolithic UPS units. The ability to add modules incrementally aligns perfectly with budget-conscious growth strategies, especially in mid-sized enterprises looking to optimize their power infrastructure over time.

Frequently Asked Questions:

What makes the BKH Series different from standard UPS systems? Unlike fixed-capacity models, the BKH offers true modularity, allowing users to scale capacity in increments without over-provisioning. This not only improves energy efficiency but also reduces initial investment costs and simplifies lifecycle management.

Can I replace a faulty module while the system is running? Yes—thanks to hot-swappable components and redundant architecture, modules can be replaced without interrupting power output, ensuring zero downtime during service operations.

Is this UPS compatible with lithium-ion batteries? Absolutely—the BKH supports LiFePO4 battery technology, which provides longer lifespan, faster charging, and higher energy density than conventional lead-acid alternatives.

How does the system maintain high efficiency under varying loads? Advanced digital signal processing and optimized IGBT switching ensure consistent efficiency above 95%, even at partial load levels—a critical factor for modern green data centers aiming to reduce PUE (Power Usage Effectiveness).

What environmental conditions does it support? The BKH Series is designed for indoor use in controlled environments with temperature ranges between 0°C and 40°C and humidity up to 95%. Its sealed enclosure and conformal coating protect internal electronics from moisture, dust, and chemical exposure.
