![]() Homebuilders, (and others), if you’re cramped for panel space, have too many switches for “non-essential” avionics, and want to protect your electronics installations from start up transients...go he http://cgi.ebay.com/ebaymotors/ws/eB...tem=4647303457 I think I have a great product at a great price. Give me your input! WHAT IS WideWire? WideWire is a completely solid-state, no moving parts, “On Delay” switch designed to protect sensitive avionics from start-up transients and then automatically power up your avionics. HOW DO I USE WideWire? WideWire will turn on avionics after a short (1-2 minute) delay, protecting equipment from the stresses of engine start. After the delay, the equipment turns on AUTOMATICALLY making important avionics, like engine analyzers and intercoms, quickly available without the wiring hassles, panel space, and pilot interaction needed by extra switches. IS WideWire DIFFICULT TO INSTALL? Not at all. As it’s name implies, WideWire is simply spliced into the power supply wire for the equipment you want to protect, and for which you want an AUTOMATIC power on sequence. It’s like a wide piece of wire! HOW BIG IS WideWire? Small. Really small! WideWire is one inch long and ½ inch in diameter. HOW MUCH CURRENT CAN WideWire HANDLE? WideWire can continuously carry 3 amps of current at an ambient temperature of +70*C (+158*F), more than enough for an engine analyzer, fuel flow indicator, or intercom. Lower ambient temperatures allow WideWire to carry more current, up to a maximum of 5 amps at room temperature (+68*F). A 3 amp fuse or circuit breaker will provide full protection for WideWire and its load with proper wiring technique. WILL WideWire INTERFERE WITH MY OTHER AVIONICS? No, it won’t. In this day of “digital”, WideWire is a simple analog device, designed to ramp up power to the avionics attached to it gently. You won’t even hear a “pop” or “click” in the headset when WideWire does its job. WILL WideWire WORK ON MY 28 VOLT SYSTEM? Absolutely! WideWire will work reliably over the range of 5 to 30 volts, but the time delay will vary. On a 28 volt aircraft, the “On Delay” will be roughly 30 seconds, more than enough time for protection from engine start-up transients. WILL WideWire TIME DELAY EVERY TIME I CYCLE POWER? No, it won’t. The turn-on delay function of WideWire also works in reverse. It has to be turned off for a period roughly equal to its turn-on delay before it will delay again. So the equipment powered by WideWire will be instantly ON if you cycle the aircraft power after WideWire has come on line. This is a valuable avionics trouble-shooting and safety feature built into the design of WideWire. IS WideWire TSO’d OR PMA’d? WideWire is built to the highest aerospace standards, but there is no Technical Standard Order (TSO) for an item like WideWire. Nor is WideWire Parts Manufacturer Approved (PMA), so it’s only useable on experimental or homebuilt aircraft. Contact your local FSDO for using WideWire on certificated aircraft under a field approval. We’ll be glad to help with engineering documentation. IS WideWire WARRANTED? WideWire is unconditionally warranted for 5 years from the date of purchase. If it fails within that time, just ship it back to us and we’ll ship you a new WideWire in return, no questions asked. |
