Low Frequency Online UPS 80KVA UPS unit power supply power factor 0.9 / 0.8 RS232 EPO
Transformer base
The RSUN DP33 Series is a robust three-phase online UPS ranging from 10kVA to 200kVA, built on true double-conversion architecture to deliver seamless, pure sine wave output with zero transfer time, ideal for critical industrial and IT loads.
Powered by advanced DSP and microcontroller-based control, it ensures real-time monitoring, precise voltage/frequency regulation, and high efficiency under unstable power conditions. It guards against power anomalies such as surges, dips, harmonics, and transients.
With support for RS232, SNMP, and GPRS, the DP33 enables flexible remote management and system diagnostics. Its modular, tower-based design ensures easy scalability for growing power demands.
FEATURES:
• Advanced DSP for precise system control
• Excellent electrical performance and reliability
• Modular design with N+X parallel redundancy (battery sharing supported)
• Dual AC input for enhanced power flexibility
• Front-access for easy operation and maintenance
• Intelligent battery management (charging/discharging optimization)
• Flexible battery configurations and layouts
• Remote monitoring via multiple communication interfaces
