Low Frequency Online Industrial UPS 10-200KVA Transformer base 3 Phase UPS DSP control 380V Industrial Online UPS, Transformer base

The RSUN DP33 Series is a high-performance three-phase online UPS system, available in power capacities from 10kVA to 200kVA. Designed with a true double-conversion topology, it ensures continuous, pure sine wave output for mission-critical industrial applications requiring zero transfer time and precise power regulation.

The DP33 Series leverages advanced Digital Signal Processor (DSP) and fully microcontroller-based architecture for real-time system control, enhanced power conversion efficiency, and accurate fault detection. This architecture enables superior voltage and frequency regulation under a wide range of input conditions, providing robust protection against power disturbances such as surges, sags, transients, and harmonics.

With flexible communication capabilities including RS232, SNMP, and GPRS interfaces, the DP33 Series supports remote monitoring, diagnostics, and network integration, making it ideal for complex IT and industrial infrastructures. Its tower-type form factor and scalable design further support modular deployment in high-demand environments.
