Prostar PHTH Series High Frequency Online UPS is a compact and powerful solution for applications where continuous power supply is critical. With a capacity range of 1kVA to 3kVA and supporting output voltages of 220VAC/230VAC/240VAC, these UPS systems are designed to provide clean and stable power to sensitive equipment. The high-frequency online double conversion technology ensures that the output power is free from mains-borne disturbances, while the DSP control offers precise regulation and monitoring. The ability to start up without a battery and the wide input voltage and frequency ranges make these units adaptable to various power environments, including those with unstable power or the use of generators. The cold start capability and optional remote On/Off function enhance the system’s flexibility, while the ECO mode optimizes operational costs. The auto-sensing of input frequency and the frequency converter mode allow the UPS to adapt to different power sources, and the active input power factor correction ensures high energy efficiency. The PHTH Series is also designed to handle specialized loads, such as laser printers and ultrasound systems, making it a versatile choice for diverse applications.
The PHTH Series UPS stands out for its reliability and robust design. The use of a strong glass fiber base (FR4) double-sided PCB, combined with well-designed ventilation and conformal coating, ensures durability and long-term reliability. Standard RS232 communication and optional USB/MODBUS/RS485/SNMP/AS400 cards provide flexibility in integrating with various monitoring systems. This series is not just a power backup solution; it’s an investment in the continuous operation of critical systems, protecting against data loss, and ensuring uptime in business-critical environments.
