Power rating<\/h2>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t

The maximum output power that the GPU can deliver continuously under normal conditions.<\/p>\n

For aircraft power rating kindly refer to this lising<\/a>.<\/p>\n

One Plug One GPU<\/strong><\/p>\n

ITW GSE believes in the \u201cOne Plug \u2013 One GPU\u201d concept as this gives the best voltage quality at the aircraft plug. Right where it matters.<\/p>\n

Since the max. power that an aircraft plug can transfer is 90 kVA, it makes sense to let this criteria determine the rating of the GPU.<\/p>\n

One may not always be able to exploit the total GPU power at the time of installation, but with the ever increasing power requirements of modern aircraft, it is almost certain that full power will be required after a few years.<\/p>\n

Of course, it goes without saying, that for power requirements above 90 kVA i.e. 180; 270 and 360 another GPU is simply added.<\/p>\n

The One Plug \u2013 One GPU philosophy makes it possible to take advantage of ITW GSE\u2019s patented \u201cPlug & Play\u201d system \u2013 an outstanding voltage compensation system.<\/p>\n

Civil Interlock<\/h2>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t
\n\t\t\t\t\t\t\t
\n

The EF interlock is a personnel and equipment safety feature in all commercial aircraft. This 28 VDC signal is not present till the GPU closes it’s output contactor and provides 400 Hz power to the aircraft. The aircraft evaluates the 400 Hz power. If within the aircraft\u2019s tolerance limits, the aircraft closes a relay in the aircraft thus providing a 28 VDC signal to the \u201cF\u201d pin\/wire in the power connector plug\/cable.<\/p>\n

Some load banks do not provide this EF Interlock. In this case, the EF interlock function in the unit should be bypassed.<\/p>\n

This setting is only to be\u00a0used by qualified personnel for testing of the GPU or in case the unit shall provide power to equipment other than an aircraft. Do not set this value to Bypassed for normal operation with an aircraft connected.\u00a0<\/em><\/p>\n

Note!
\nThe value will be automatically reset (from bypassed to Active), if the unit detects a 28 VDC signal to the \u00ab\u00a0F\u00a0\u00bb pin.<\/p>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n \n

On the back of the unit, look for a metal plate indicating the serial number.<\/p>\n
