Tid for en aldri saa liten update igjen, det som staar for tur naa er det sentrale strom fordelings-systemet i AAPEN, forovrig kan det nevnes at AAPEN er open-source, all programvare er lisensiert under GPL Version 3, hardware, design og hw-spesifikasjoner er lisensiert under TAPR NCL (ala. GPL for HW) og kan kopieres og benyttes fritt til alt ikke kommersielt bruk.
A package from one of my very favourite electronics vendors, Altronics.
Lots and lots of relays. These relays are designed specifically for use in high-current high-temperature industrial installations.
And yet another batch of relays.. earlier tested types and models etc.
Constructing the AAPEN relay clusters.
Wiring up the relay clusters.
The solder used on the relays is certainly not RoHS compliant solder with a high lead content makes better joints with the copper conductor, and this is very important considering the very high currents in the system. Just got to make sure to wash hands afterwards
The wires used are 32x 0.2mm (17awg) and rated for use in high-current applications.
Heat shrink, this stuff requires a very high tempearture to shrink, using the butane iron’s furnace is great for this.
And more wires. In total about 64 meters of high-current wiring, alongside 10-15 meters of low current wire is required for each cluster.
The completed relay cluster.
Taking the AAPEN Relay Clusters for a test run. Looks good
Bench testing to ensure the currents and voltages experienced in the system is within the ATX 2.2 specifications.
(Actually, all AAPEN components and wiring is rated at very minimum twice that of the ATX2.2 specs…
The voltages look really good as well
