KID-Systeme GmbH - June2000 - All Rights ReservedHOW MANY PASSENGER WILL USE IT ?
Some power is available
15 VOLT - MARKETING ASPECTS
The Hypertronic outlet is small, discreet and easy to integrate
Neither the 15 VDC power output nor the receptacle respond to computer industry
standards (there may be some exceptions)
Additional DC-DC laptop power transformer are required (approx. 60 different types
on the market, priced US$ 80 - 100)
Providing adapters to passengers is a serious cost and logistic challenge for the
airline
Not to provide the adapters means not to respond to the passengers’ expectations

15 VOLT - TECHNICAL AND SAFETY ASPECTS
15 VDC voltage is not considered critical
A third manufacturer’s adapter breaks the chain of OEM equipment
(ISPSS -- notebook)
The power outlet is small and easy to integrate into the seat
Existing 15 VDC - 110 VAC transformer (some manufacturers offer such products)
are of potential danger when operated by passengers without any system safety
protection
Not all third party adapters correspond to airworthiness qualification standards
(DO 160) and the notebook manufacturers’ specifications
Potential risks: Grey market, EMI problems, unregulated battery charging

KID-Systeme GmbH - June2000 - All Rights ReservedMEET THE PASSENGER’S EXPECTATIONS
110 VOLT - MARKETING ASPECTS
The passengers can operate their laptop computers like at home
No additional voltage transformer is required
(Non-US notebook computers operate in the range of 110 - 240 VAC @ 50/60 Hz)
No additional cost and logistic issues for the airlines
Instant access meets the passengers expectations
Crew / passenger instructions are required in order to advise passengers

110 VOLT - TECHNICAL AND SAFETY ASPECTS
The notebook OEM transformer meets the individual specifications of the notebooks
This supports a continuous chain of OEM equipment
The load limit of 75 W does not allow operation of hair dryers or other critical
equipment
Additional passenger safety features in the seat end
GFI, mechanical locks, over-voltage / over-current protection, load sensor, plug sensors
The size of the outlet unit may require more seat engineering skills

CERTIFICATIONASPECTS
0
KID-Systeme GmbH - June2000 - All Rights Reserved
Following items are relevant to AC-Systems:
JAA policy harmonised with the FAA, based on previous FAA Memo
“No conventional duplex outlet, special adapter required”
Objective: to control access of the in-seat power system
Compliance: the outlet accommodates normal Euro/US duplex connectors, but the built-in safety features provide a safety equivalent to a special adapter.
“Indication of power outlets in use”
Objective: to allow easy monitoring of in-seat power use by the cabin crew, in particular in a dark cabin on long range flight
Compliance: final ISPSS standard has an indication light on the aisle side of each seat group

A damaged PED power cord under load is trapped under the flap of the folding table in the seat armrest.
After the cord is cut through a short circuit or a ground fault switches off outlet power immediately.
