Prostar PHRH Series Rack Mount Online UPS is a compact and powerful solution designed for critical power needs in 19-inch and 23-inch power cabinet systems. With a capacity range of 6kVA to 10kVA and a high input power factor of over 0.99, these UPS systems ensure efficient and reliable power supply for sensitive equipment. The series stands out with its three-level inverter technology, which minimizes harmonics and enhances efficiency, providing clean and stable power even during critical operations. The wide input voltage and frequency range accommodate various electric environments, making the PHRH Series compatible with generators and suitable for diverse applications.
The UPS systems are built with high-purity raw materials, ensuring minimal self-discharge and maintaining power integrity over time. They also incorporate gas recombination technology, which increases sealing reaction efficiency, prevents mist precipitation, and contributes to their safety and environmental friendliness. A special design preserves the electrolyte fluid, eliminating the need for water addition during service life, and the unique corrosion-resistant grid alloy extends the float life significantly. The PHRH Series is also equipped with advanced communication options, including standard RS232 and optional USB/MODBUS/RS485/SNMP/AS400 card, allowing for flexible integration with existing monitoring systems. The reliable design, featuring a strong glass fiber base and conformal coating, ensures durability and long-term performance in even the most demanding conditions.
