The RSUN PM Series delivers a new standard in modular UPS
performance, combining true online double-conversion topology with
a dual high-speed DSP core for precise control and fault isolation.
Its modular architecture enables seamless capacity upgrades and N+X
redundancy, supporting scalable configurations from medium-sized
deployments to large mission-critical facilities. With advanced
rectifier sharing, synchronized module management, and three-level
inverter design, the system achieves excellent energy efficiency
and load stability.
Built for 24/7 operations in data infrastructure, industrial
automation, and high-availability environments, the PM Series
minimizes downtime, streamlines maintenance, and ensures continuous
power protection even under dynamic load conditions.
FEATURES:
1. Up to 96% system efficiency, minimizing energy and cooling
costs.
2. Supports modular configurations with 20 kVA or 25 kVA modules,
scalable from 20 kVA to 300 kVA.
3. User-friendly interface with intelligent monitoring and control
functions.
4. N+X redundancy design allows up to 20% backup capacity at full
load, achieving Class B rack availability.
• Example: 200 kVA = (10+2) × 20 kVA, 300 kVA = (6+1) × 50 kVA.
