The 3Phase Delta IntelliStrip provides a convenient
way of supplying 3 phase monitored power to a cabinet.
Each DeltaStrip is provided with 3 sets of 5 socket outlets
as standard (3 x IEC C19 and 2 x IEC C13). (Alternative
socket configurations are also possible).
Star (Wye) and Delta configured.
The Delta IntelliStrip is fitted with a 4 pin 32A inlet connector (IEC 60309 Commando or equivalent). Each group of 5 IEC outlets is wired between two phases and there is no neutral connection.A Star-configured strip is also available (See the Star IntelliStrip datasheet for details).
Power measurement of a delta configured IntelliStrip uses the 2 Wattmeter method of measuring overall strip power. The software presents this as power per phase, allowing the user to see power per phase across the whole datacentre, regardless of whether devices are star or delta configured. In addition the current per phase and the voltage between phases (ie across the sockets) is also presented. Optionally, each socket’s current may be individually measured.
Regulations vary from country to country and it is our experience that interpretation of the same regulation also varies. In some regions the requirement for circuit protection is that it must be provided within 3m of the conductor rating change. This means that the circuit protection for individual socket outlets does not have to be provided on the strip, it can be provided by fuses within the plug top (eg British 13A plug tops), or it may be provided on the equipment at the end of an IEC lead. IntelliStrips may be fitted with individual fuses per outlet, or for customers who do not want multiple points of failure, the IntelliStrips may be supplied without fuses. At present, only one fuse per outlet is possible on an IntelliStrip. Care must be taken to provide adequate circuit protection for both phases wired to sockets on a Delta 3Phase IntelliStrip.
