Mission Critical MC

The mission critical (MC) provides redundant operation using two sources feeding

one common group of output distribution devices. By integrating a Cyberex

SuperSwitch®3 digital static transfer switch (DSTS) and Cyberex power distribution

unit (PDU), the MC provides the highest level of customization for diverse equipment

loads and maximum growth. Coupled with advanced communications and branch

circuit and Sub-feed circuit management, the MC is the key design element for

ensuring maximum uptime for your facility.

Waveform capture

SuperSwitch®4 is available with waveform capture.

The waveform capture feature uses digital signal

processors and high speed analog to digital

converters to simultaneously sample sources and

output voltages and currents. The waveform data

is collected every 0.1 millisecond intervals as 12 bit

samples to provide an extremely high level of accuracy.

The SuperSwitch®4 is capable of storing 20

waveform capture events for both transfer and

non-transfer events. Each measurement contains

a total of 10 cycles; 5 cycles prior to the event and

5 cycles after the event. The waveform can be

downloaded as an image file from the display USB

port for additional viewing and analysis.

Software-guided breaker operation and bypass

Easy to follow commands and indicator lights

eliminate the causes of human error.

Data and alarm management

With over 100 warnings/alarms types, 5000 events

can be stored or downloaded to a USB device for

analysis.

Remote access

Compatibility with building management systems

provides access from any location at any time.

Expert power management

The SuperSwitch®4 harnesses the power of touch with an innovative user interface

that utilizes a 10.4″ color TFT industrial use VGA LED touchscreen GUI for self-guided,

serviceability with minimal engagement, and the latest communication protocols.

How does it perform?

The Real Time Flux Control™ is the optimal

solution for inrush reduction, it cleanly

disconnects the failing source and transfers the

critical load to a more reliable power quality

source. Figures 2 and 3 show an out of phase

emergency transfer done on a 480 volt, 600 amp

STS feeding our 225kVA PDU transformer, the two

sources were 60 degrees and 180 degrees

respectfully, and the transfer mode selected was

the recommended “DIR limited.” The outage time

was measured to be 5.50 millisecond in the first

case and 11.30 milliseconds in the second with no

inrush observed.

An intelligent method for Dynamic Inrush Restraint

•   Makes secondary switching (one PDU transformer) reliable.

•   Eliminates the need for complex inverter control schemes.

•   Maintains true independence between UPS systems (higher reliability).

•   Keeps inrush value lower than 1.2x.

•   Exceeds the ITIC and CBEMA curves standards

for critical loads, see figure 4 above.

•   Smoothly transfers the load without creating

unnecessary voltage discontinuity and

disturbances to the load.

Dynamic inrush restraint for applications with downstream transformers

Inrush currents degrade power quality Static Transfer Switches (STSs) are essential

components in data center power system configurations. Mainly relying on transformers

primary side switching, these devices are the bridge between the power sources and the power

distribution units. This architecture offers many advantages to the customer in terms of smaller

footprint and lower costs; however, if not properly switched, high transient inrush in downstream

transformers will occur.

The inrush currents produced degrade the power quality of the preferred source, overload upstream

UPSs and trip protective circuit breakers. The inrush currents can also create intolerable forces in

the windings, which in turn reduce the lifecycle of power transformers as these currents can reach

the short circuit rated value and can last many cycles before they dissipate.

Real Time Flux Control™ for DIR With state of the art digital signal processors and a

newly developed algorithm, an innovative approach was created called Real Time Flux Control™ for

dynamic inrush restraint (DIR.) Using advanced Real Time Flux Control, SuperSwitch®4 can

dynamically monitor and adapt its transfer switching to account for any variation or condition

that may occur during an upstream outage. Real Time Flux Control enables out of phase transfer

times that are 25% faster and inrush currents that are 40% lower than previous generation systems.

By controlling inrush currents, the SuperSwitch®4 protects upstream and downstream infrastructure

from the harmful effects of excessive currents.

This technology is an intelligent proprietary method that makes no compromise to the voltage

output for mission critical applications by providing a performance that exceeds the CBEMA

and ITIC standards, regardless of phase drift between sources.

How does it work?

The STS constantly monitors the power quality of both sources taking into account the customer

specified thresholds. In addition, three transfer modes are available to customers to choose from:

A9. DIR always and DIR limited.

A9: this mode is a proprietary method that is to be used only when the phase difference between the

sources is less than a user defined phase angle.

The range of this setting is adjustable up to +/– 30 degrees, and is not recommended for larger phase

differences.

DIR always: this mode allows the SuperSwitch®4 to permanently transfer using the Real Time Flux

Control approach and should result in low inrush regardless of how far the two sources are out of

phase.

DIR limited: this mode is the recommended setting for the SuperSwitch®4. In this mode, a hybrid

approach of A9 and DIR is performed depending on the phase difference between the sources.

Most customers use the recommended setting of DIR limited because the STS will auto select when,

and if, the DIR function is needed depending on the phase difference as illustrated by Figure 1 below.
