Prostar PHTH Series High Frequency Online UPS is designed to deliver reliable power protection for a range of applications, scaling from 6kVA to 10kVA with output voltages of 220VAC/230VAC/240VAC. This series is recognized for its high-frequency online double conversion technology, ensuring clean and stable power output. The DSP control offers precise power regulation, while the active input power factor correction maintains an input power factor greater than 0.99, which is essential for energy efficiency. The UPS can start up without a battery, and its wide input voltage and frequency ranges make it adaptable to various power environments, including those with unstable power or the use of generators.
The PHTH Series is also equipped with a cold start function, an optional remote on/off function, and an economic operation mode (ECO mode) to optimize operational costs. It can auto-sense input frequencies of 50Hz or 60Hz and offers a frequency converter mode, which is beneficial for applications requiring different frequency conversions. The UPS systems are designed to handle specialized loads, such as laser printers and ultrasound systems, and provide standard RS232 communication with optional USB/MODBUS/RS485/SNMP/AS400 cards for integration with various monitoring systems. The reliable design, with a strong glass fiber base, efficient ventilation, and conformal coating, ensures durability and long-term reliability in mission-critical applications.
