Delta UPS – Modulon Family DPH Series, Three Phase 25 – 75/150/200 kW

Delta UPS – Modulon Family
DPH Series, Three Phase 25 – 75/150/200 kW

The Modulon DPH supports ultimate availability for data center operations and provides the benefit of “pay as you go” without over-sizing the UPS.


While achieving ultimate availability, the Modulon DPH does not compromise on power efficiency performance. When availability, efficiency and expanding according to business needs are essential, the Modulon DPH is the ideal UPS system to provide power protection and total cost of ownership (TCO) savings.




  • Advanced fault tolerance design achieved by self redundancy to guarantee operation continuity
  • Self-synchronization of power and control modules for continuous on-line operation even in the event of control module failure to avoid downtime caused by single point failure
  • Hot-swappable key modules and components to ensure Mean Time To Repair (MTTR) close to zero without downtime risk
  • Vertical expansion from 25kW to 75/150/200kW supporting N+X redundancy in a single rack enclosure to save footprint
  • Parallel expansion up to four units without requiring additional hardware
  • Optional Rack-Mount Remote Power Panel (rRPP) (applicable for 75/150kW models) has flexibility to arrange its UPS’s output power feeding according to its connected critical loads
  • Optional built-in battery modules (applicable for 75kW models) at maximum four units (four battery trays each)
  • Full rated power (kVA=kW) to maximize power availability
  • High operating efficiency of 95% at 30% load and 96% from 50% load resulting in marked energy cost savings
  • Low harmonic pollution (iTHD<3%) to reduce upstream investment costs and meet demanding power requirements
  • Built-in manual bypass features to eliminate maintenance- related downtime
  • Proactive detection of fan failure and switch fault for early diagnosis on UPS malfunction
  • Plug and play modularity to simplify the maintenance process

Why Delta UPS?

The Delta Group’s operations are global in scale with 38 manufacturing facilities in Taiwan, China, Thailand, India, Mexico, Brazil and Slovakia. Delta also has 61 R&D centers across the globe and 153 sales offices on all 5 continents. Pursuing the highest quality and reliability of Delta products has been the primary target since Day 1. All of the factories have received ISO 9001 and ISO 14001 international certificates which verify that our production conforms to the corresponding quality standards and evaluation. “Do things right the first time” is the belief that Delta insists upon and continues to provide the best quality control in terms of product development and manufacturing with our primary goal of satisfying our customers. Delta’s outstanding product design capability comes from the R&D team and its various precision measurement instruments. The R&D centers utilise diverse advanced equipment and programs including CAD to facilitate circuit simulation, mechanical design, and PCB layout. Delta has nine well-equipped laboratories to conduct environment-related substance analysis, precision measurement, failure analysis, soldering techniques, electromagnetic compatibility and interference tests, material chemical analysis, quality engineering, safety tests, and more. In addition, we also have laboratories with controlled temperature and humidity to perform with numerous reliability tests including ORT (Ongoing reliability test) EMC / EMI (electromagnetic compatibility & interference), Acoustic test and the Pulse lightening discharge test.


In a nutshell:


  • Delta’s large-scale production follows comprehensive quality management to do things right the first time and deliver the best quality
  • All manufacturing sites are certified with ISO 9001 and ISO 14001 and conform to the highest quality control in terms of product development and production to achieve customer satisfaction.
  • With six laboratories accredited by the China National Accreditation Service for Conformity Assessment (CNAS) all of our products go through the tightest checks.


  • Wide input voltage range reduces the chance of battery use and extends battery life
  • High input power factor increases utilization of utilities and reduces total cost
  • High output power factor provides more real power to critical loads
  • Higher efficiency lowers operating costs
  • Lower harmonic distortion saves on upstream investment
  • Compact design saves more space for critical equipment


  • 2-year warranty
  • Service line is available through the RT Systems 24/7 call centre to answer your questions
  • Customer-needs-oriented, available with comprehensive and professional service and technical support
