DPM Gen2 Series 250-1750 kVA

OPEX Savings

• AC-AC efficiency up to 97.3%, efficiency optimization at light loads saves energy costs
• Clean mode (voltage independent mode) up to 99% efficient guarantees the optimum power condition while maintaining the highest level of efficiency
• Optimizes energy cost with off-peak charging, avoiding peak-time expense
• Elevates grid stability through responsive demand reduction and fast frequency regulation, triggers upon utility requests for eligible bill subsidies

Impeccable Reliability

• Assures smooth power transitions with integrated Synchronized Multiple Bus (SMB), minimizing transformer inrush currents and maintaining balanced power from dual sources
• Parallels up to 8 units for redundancy or expansion, supported by N+1 internal redundancy in power modular configuration
• Maximizes UPS performance and lifespan with self-diagnosis and key component analysis

Ultimate Availability

• Lithium-ion battery ready. Adjustable battery charging voltage adapts to multiple types of batteries
• Seamless power shifts to generator with an advance power walk-in function, pausing during frequency issues for smooth transitions without unnecessary generator sizing expansion
• Grid interactive application. Provides corrective operation for unstable renewal energy sources with an innovative topology design that handles grid and battery power at the same time
• Easy mounting/cabling that supports both top and bottom cable entry and full front access
