I have used the Expbus for 5 years on my KR-2. I added a 35 amp circuit breaker for the VW Diehl alternator rated at 20 amps. My system has a main battery and a backup battery. The Dynon D10A has a built-in backup battery. The Expbus keeps all three batteries isolated and charged automatically. The electronic circuit breakers work great. Most mechanical circuit breakers are rated for 10,000 trip cycles. The Expbus electronic breakers have no life-time limiting. When the electronic breaker does trip, the circuit current is limited to about 10 micro amps. Reset is automatic when the circuit is shut off with the individual power switch. The Dynon D10A and Grand Rapids engine monitor are switched on with the master power switch; these have electronic circuit breakers also. The electronic ignition, starter relay, fuel gauges, lights, radios, GPS, intercom and mixture meter are switched through the Expbus, all with the right-sized electronic circuit breakers. The printed circuit card has one massive ground lug for connecting a single point ground; this is a great feature for noise suppression on the radio and headsets. I cannot attest to the company's long term viability. I am quite pleased with the operation of their Expbus.
Sid Wood Tri-gear KR-2 N6242 Mechanicsville, MD, USA ------------------------------------------------------------------------------ Dan asked, > "Is that the same company that put out Anywhere Map which is now defunct?" I guess Craig will tell us how defunct they are regarding this product he's either ordered or received. They still show this EXPBUS as something they have in stock and are shipping but I wouldn't expect any sort of customer service following the sale. Hopefully if Craig has ordered this unit he won't need any customer service long-term. Control Vision appears to be selling their remaining stock of whatever is left in the warehouse. Something that concerns me about this unit is that it says it uses a sophisticated design that takes the place of conventional breakers or fuses and will automatically re-set after an appropriate interval if there is an overload on that circuit. What if a person wants to take that circuit off line? I guess in that case you'd just turn the circuit off using the switch for that circuit. Is that how it works Craig? This is advertised by Control Vision as an "advanced feature". I like the all-in-one design that simplifies organizing ones electrical system. Hopefully Craig can tell us more about it. It looks like something that could save a builder some time putting the panel together. ____________________________________________________________ I am using the "Expbus 2V DC Load Center Toggle" unit. Simple and straight forward.

The breakers open when an over current happens. It then has a drain circuit that keeps a little current flowing to keep the breaker tripped. When you turn off the associated switch the current drops to zero and the device resets. All good in theory and Sid has actually used it so I would refer any question to him. Craig
