10 Things to Consider When Buying flatpack 1800

Searching for a adaptto charger i've came across with this power supply very similar to the Eaton APR48-3G, but a little better IMO.
I made a little comparison with the two power supplies / module rectifiers:

Operating Voltage range: 85-300V AC (ELTEK) --------- 90-300V AC (EATON)

Efficiency (max): 92.5% (ELTEK) ---------- 92.0% (EATON)

Power output: W @ 185-275Vac (ELTEK) ----------- W @ 208-240Vac (EATON)
850W @ 85Vac (ELTEK) ----------------- 900W @ 100Vac (EATON)

Default output voltage: 53.5V (ELTEK) ---------------- 54.5V (EATON)

Adjustable Voltage range: 43.5-57.6V (ELTEK) -------------- 43.0-57.5V (EATON)

Weight: 1.9kg / 4.2lbs (ELTEK) ----------------- 1.7kg / 3.7lbs (EATON)

Dimensions: 109x41.5x327mm / 4.25x1.69x13" (ELTEK) ------------ 130x42x266mm / 5.1x1.6x10.5" (EATON)

here is the datasheet:
They have also a W version:
and a 48v-60v version:

I bought it new for less than 100EUR with shipping from here:

Pinout:


Type of connectors:


I've flattened some female bullet connectors to power on and to make a charge test:


I didn't try to push more than W from the ELTEk (i've limited the maximum current from power supply in adaptto to 37.4A).
I will try later to see if i can push more power.

According with the datasheet the ELTEK can adjust the voltage output but i don't know how to adjust it (for now). I know that it is possible with a Module Controller that connects via CAN but without it i don't know how.I really appreciate if someone could help with the voltage adjustment.

Here some user guides and tests that i found about the ELTEK:

Best Regards.

I've been poking around with my Flatpack2 HE but not really got started on a build yet.

Does anyone know what the third contact with the CAN H and CAN L is? I've stuck a 'scope on it but can't tell what it is.

I assume that when taking 12V from the fan that you also need to take the corresponding ground and link this to the - output. The fan supply seems to be isolated from the main output and this ties it back in. I know this will work, but I'm sure there must be a more suitable 5V somewhere to go with the CAN bus. It's just a pain to find with all that varnish all over everything.
