Cyberex® RPP with ABB High density solutions

High density solutions

Cyberex offers the complete current limiting, selectively coordinating solution for

your high power, high efficiency data center

The industry demand to increase data center

efficiency and push the limits of power density at

the rack has introduced new design trends. While

one proposed solution, raising the distribution

voltage in the whitespace, helps meet these

demands, data center systems designed at higher

voltages (415V, 480V) provide system owners and

designers with a new set of challenges and

concerns to overcome.

Selective coordination,increased arc flash potential, protecting sensitive

IT equipment and complying with SCCR and IR

code requirements take center stage. These

heightened concerns are mainly driven by the

removal of a transformer and the potential

increase in available fault current when compared

to traditional 208V designs. With the high available

fault currents, average main and branch breaker

combinations will not allow branch breakers to trip

independently of the main, forcing the shutdown

of an entire panelboard to clear an overcurrent on a

branch circuit. This lack of coordination will in turn

cause unnecessary downtime to critical server loads.

Current limitation

ABB’s utilization of current limiting circuit breakers

brings a whole new level of protection and peace of

mind to the distribution of electrical power on the

data center floor. Two of the most notable benefits

of current limitation are increased protection for

downstream system components and the

mitigation of arc flash hazard for workers. Both

mechanical and thermal forces are drastically

reduced through current limitation, which in a data

center, means less potential damage or strain on

the sensitive and expensive IT equipment. This

heightened protection helps remove worries of

extended downtime due to repairs or replacing of

damaged equipment. Current limitation is also the

driving factor to reducing the energy released

during an arc flash event.

Cyberex® RPP with ABB ProLine panelboards ​Selective coordination

Selective coordination

Selective coordination defines a system’s ability to

isolate a fault and increase system reliability. If a

fault was to occur in a selectively coordinated

system (Figure A) the overcurrent protective device

closest to the fault will clear the fault and leave the

rest of the system undisturbed. If the system was

not selectively coordinated, (Figure B) like the

majority of standard RPPs, the breaker closest to

the fault may or may not clear the fault before

upstream breakers start to open causing

unnecessary loss of power to critical loads.

Safety

Working on live electrical equipment is never

recommended, however sometimes becomes a

‘necessary’ task due to the criticality of system

loads in a data center. Cyberex RPPs significantly

enhance worker safety due to its touch safe

panelboard chassis and plug in current limiting

branch breakers. Along with drastically reducing the

shock hazard, the use of current limiting breakers

significantly reduces the arc flash potential to which

a worker could be exposed. Both benefits help users

comply with NPFA 70E guidelines and OSHA standards.

Installation

• Installation should not be attempted without refer

ring to the applicable Programmable Controller

Installation Manual (see reference 5).

• Make sure rack power is off.

• Install expansion memory if required.

• Connect the battery to either of the battery con

nectors on the module. (See figure 2)

• Install in the rack. (See figure 1)

FOXBORO 130M Series Simple and cost-effective installation

Simple and cost-effective installation

Up to 10 instruments can be accommodated in a multi-unit rack. All air connections are made when the controller is installed in the rack.

Piping costs are minimized as each rack has its own integrated air supply header and individual air shutoff valve.

Easy Maintenance

The 130 Series utilizes a unique pneumatic circuit board that greatly enhances the sophistication of the pneumatic control system.

This board eliminates many of the piping and connections found in other controllers.

All components are located on one side of the board and are easily accessible by sliding back the cover on one side.

Force Balance Control Module

The proven force balance control module ensures long service life and reliability.

Due to the use of metal bellows, there is virtually no movement in the flexure suspension mechanism, thus providing the user with a clearly superior controller.

Specialized Controllers for Every Application

Foxboro offers the industry’s widest range of optional accessories and specialized control features.

In addition to normal control modes, these include single-station ratios, single-station computer setups, auto selectors, differential gaps, and “batch” processing.

FOXBORO 130M Series Separate automatic and manual control units

Separate automatic and manual control units

Both the automatic and manual control units can be disassembled without disrupting the process.

This design feature avoids costly downtime for servicing the controller.

Completely Unbalanced and Bufferless Transmission

The 130 Series controllers utilize the “integral balancing” method for bufferless transfer.

After transfer, the controller simply responds at the integral (reset) rate that

This eliminates any error between setpoint and measurement.

In addition to providing easy, unbalanced and unbuffered transmission, this solution preserves the

setpoint.
