Safe Swap Modules

The Conceptpower DPA TM Modules are fully independent and are composed of all major hardware and firmware building blocks:

  • CPU (Central Processing Unit)
  • All power circuits (rectifier, inverter, battery charger)
  • Static switch and static switch control
  • Power Management Control Panel





hot insertion and removal of modules from a host system without removing power.

In a redundant Power Protection System Safe-swap is achieved only if a module may be added or replaced Without interrupting the power to the Load and w/o having to transfer the load to the raw mains (by-pass).

- High availability of power protection systems

- Safe scaling-up of system

- Easy fault recovery

Parallel Architecture

Power Protection Parallel Architectures

There are two basic Power Protection Parallel Architectures available today:

These two architectures differ by the level of decentralization of their building blocks.

Parallel System Architectures are designed to increase Power Protection Availability, which cannot be achieved by STANDALONE UPS’S.

  • Central Parallel Architecture (CPA) and
  • Decentralized Parallel Architecture (DPA)

Centralized Parallel Architecture (CPA)(Legancy Modular UPS)

  • CPU
  • Control Panel
  • Static Bypass Switch
  • Battery

The only Decentralized Parts are the Power Units.

In a Centralized Parallel Architectures the system is composed of common system building blocks:

Centralized Parallel Architecture

Single point of failure describes any part of the system that can, if it fails, cause an interruption of required service. This can be as simple as a process failure or as catastrophic as a computer system crash.

Decentralized Parallel Architecture (DPA)

  • Control Panel
  • CPU
  • Power Unit
  • Static bypass switch and

Decentralized Parallel Architecture (DPA) was designed to distribute virtually the entire UPS Hardware and Software into modules in order to reduce the Single Points of Failures (SPOF). DPA includes distributed

Decentralized Parallel Architecture

Exclusively Decentralized Parallel Architecture (DPA)

  • Each critical building block is decentralized
  • - No critical Single Point of Failure

  • Full redundancy on Static Bypass Switch (SBS)
  • Multi Master and Slave Technology through a simplified BUS Communication
  • Full redundancy on inverter
  • Back Feed protection integrated or optional

Static Bypass Switch (SBS) Redundancy

To achieve highest level of availability in Multi-Module configurations it is essential that also the SBS be redundant.


In-line contactors for Rectifier andBypass-Input for "back feed protection" .....increased service personnel safety


Right Sizing ??

  • Large space required : expensive
  • Large cables : expensive
  • Lower efficiency : high losses
  • Dedicated cooling system: expensive

Scalability brings Flexibility


High Availibility

To achieve near-zero downtime and avoid very costly consequences of disruption of Mission Critical Applications, advanced Modular Power Protection Architectures with High Availability must be employed.

In Business Critical Applications a new availability strategy with near-zero-downtime is required to reduce the risk of threat to the business….the: Continuous Power Protection Availability

Newave modular concept offers a new way of thinking when conceiving a Data Centre

10 reasons for choosing a Newave modular UPS

  1. Optimize capital investment and available space

    Pay-as-you-grow solution lowers your capital costs and increases utilization rates, while innovative rack-based technology frees up space previously needed for infrastructure support.

  2. Adapt to ever-changing power requirements

    No need to abandon previous investment when power density needs increase or if physically moving your data centre. Adapt to changing wattage requirements in your racks with single-or multi-branch rack-mount power distribution units.

  3. Accelerate speed of deployment

    Electrical and physical modularity allows for rapid installation with minimal engineering.

  4. Lower the cost of service contracts

    Simplicity of system design and intelligent modular parts lessen the dependency on expensive service contracts.

  5. Increase availability

    Specifically engineered to deliver higher availability through proactively designed, building block architecture and reduced MTTR

  6. Decrease mean-time-to-recovery (MTTR)

    Compartmentalize potential failures with system components consisting of intelligent, maintainable modules for quick fault recovery.

  7. Plan for a power density that is increasing and unpredictable

    Eliminate hot spots in your data centre caused by higher power densities by targeting availability where you need it most.

  8. Minimize points of failure between the UPS and the critical load

    Move redundancy closer to the load and prevent the majority of failures that cause critical load downtime.

  9. Minimize human error

    Simplicity of design and intelligent modules increase system availability by mitigating human error: the number one cause of critical load downtime.

  10. Decrease the operating costs

    With efficiency up to 96% (double conversion mode), the operating costs for a Conceptpower DPA modular UPS can be >40%less compared to those for a previous generation.

With the modular, safe swap UPS systems, you can build your own IT-Facility to meet simultaneously and most accurately:

  1. Higher Availability
  2. Unmatched flexibility to changes
  3. Unmatched flexibility to changes
  4. Lowest TCO
  5. Product standardization
