Good day all.

Can anyone here please help me identify this Electrofit Zapi Ltd High Frequency 48volt Controller?



From looking on google ect, it looks to be a version of the H2 Model, but I am not sure what version.

I can't find any part / model number stamped anywhere on the unit, the only stamped marking is "E6348" and I am guessing this in the units serial number.

And can anyone tell what the little black box in the top centre is?

Thanks for your time.

Best Regards.

have you tried ringing up on the telly using what looks like the phone number under the union jack?

or google the number and see if it matches the case name

piotrsko: It is indeed a UK tel number, but being a weekend there was no answer, I will be trying to contact someone again today.

Just been on the phone to Electrofit Zapi Ltd, and spoke to a nice lady, that confirmed it is an old Zapi H2 model.

I then asked about the programming console, and serial cable + PC software.
Programming Console £236.34 + VAT.
Serial cable & Software £233.31 + VAT.

[piotrsko]

sounds like you need to contact hyster and see if they can do the programming for you. 400 pounds sounds a bit pricey for a one-shot

I have been able to find the Zapi PC Software, and after some reverse engineering, I was able to make a serial interface cable.

I am now able to change all the settings within the Zapi controller.

Also the controller logs hours of use, and if the reading is right this controller has only had 675h of running use.

Below is the exported data that I was able to pull from my Zapi H2 Controller.

I have had a number of people sending me private message's asking for my details on this Zapi H2 unit.

One questions that I get asked often is: what is the max voltage / amps can this unit cope with.

I know Zapi have a range of voltage and current models.

So I have pulled my unit apart to have a look at things.

I can see it may be possible to change a few parts on the logic board so that it would be able to cope with higher voltages, but I am more interested to find out the voltage and current limit of the power board.

Here is a list of some of the parts on the logic board
