Prostar PHTD Series Dual Phase High Frequency Online UPS is a powerhouse in the UPS industry, designed to deliver reliable power protection for a range of applications. With capacities from 6kVA to 10kVA and output voltages of 220VAC/120VAC, this series stands out for its versatility and efficiency. At the heart of the PHTD Series is a DSP control system that ensures precise power regulation, while active input power factor correction maintains an input power factor over 0.99, which is crucial for energy efficiency. The three-level inverter technology reduces harmonic distortion, providing clean power to sensitive equipment. The UPS systems also feature a galvanic isolation transformer between the AC input and output in all operating modes, enhancing safety and reliability.
The PHTD Series is designed to accommodate a wide range of power environments with an input voltage range of 90V to 300V and a frequency range of 40 to 70Hz, making it compatible with generators and various power grids. The cold start capability and optional remote on/off function add to the system’s flexibility, while the economic operation mode (ECO mode) optimizes operational costs. The UPS systems can auto-sense input frequencies of 50Hz or 60Hz and offer a frequency converter mode, which is beneficial for applications requiring different frequency conversions. They are also 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, featuring a strong glass fiber base, efficient ventilation, and conformal coating, ensures durability and long-term reliability in critical applications.
