mot. 4 812 Netzgerat Powersupply EN

Hi, I just received an unused mot. 4 812 power supply, the 30173 1975. The ones sold in Australia have an Approval label stuck over the original bottom third of the top panel, see the picture attached. In Australia, we typical have 240 V ac. At my house its typically above 245 V ac and sometimes 250...

Re: Red Power Controller - Low side FET

I think what Codex is trying to say is that it's easier to connect stuff if it all shares common ground. If you e.g. want to use the TXT to read the output voltage of the Power Supply. How would you do that? That's a little tricky as the TXT expects a positive input signal relative to ground and th...

Red Power Controller - Low side FET

With reference to the ft Power Controller, that has 9V DC Out and adjustable Motor output. For the motor output, it uses a Field Effect Transistor (FET) that is connected to the ground reference, so as you rotate the dial, the ground reference shifts up and down. In other words the voltage reference...

Re: Transistor part number and data sheet in u-t 4

Thanks H.A.R.R.Y. Schematics are useful, confirms the simple PCB layout. Thanks for pointing to the link for them. I check the Transistors, they are working. I was more interested in the maximum and electrical characteristics for the transistor, hence the part number and the datasheet. Cheers Michael

Re: Transistor part number and data sheet in u-t 4

Never mind, I found it.

BC108A

It's in the manual for the u-t 4 :)

Transistor part number and data sheet in u-t 4

Hi,

Does anyone know what the transistor part number is and where there might be a datasheet for the transistors that are in the u-t 4.

The transistor are in follow two parts:
3 36735 1 Transistor/Potentiometer-Bausdtein
3 36733 1 Verstarkerbaustein

Thanks
Michael :)

Re: Hobby Experimente & Modelle Bucher - Englisch

Hi Burkhard, I have some of those black and white translations booklets too, they are no fun to read, no pictures. Experimente+Modelle“ books that you seek were never published in English At least the two that I have were published in English. I will provide a picture of the front covers. The Englis...

Re: Incline Elevator

Hi Stefan, Wow nice job on the extensions. I been thinking about some sort of mechanical tilt unload-er for the tilting bucket or a crane. My relay logic with 2 light beams, 2 h4RB and 2 switch is also working fine now. I would really like to go to the Convention in Dreieich in September and bring s...

Re: Incline Elevator

Hi Stefan, I have it working as per the diagram on page 62 using the two additional h4G and one switch. It stop at the bottom of the incline, starts going up when you press the button, and when it reaches the top and breaks the light beam it reverses and travels back down. One side of the PB switch ...

Re: Incline Elevator

Hi Stefan, here https://ft-datenbank.de/details.php?Art ... bd023c6bd8 on page 13 we can see that they actually used *2* buttons, one underneath each relay. So I guess the original model was quite simple: Each button just shortcut one of the self-inhibiting relays, one for up, one for down. Yes, I h...

Re: Incline Elevator

Ohh.. I see my error now, thanks Stefan. I thought it had one relay. Yes, I can see how it can be done with 2 h4RB relays. This picture show my attempt using one h4RB relay and one h4GB Elecktronik-Grundbaustein. I have another h4GB relay and will try it later when I get home. Thanks for your help :...

Incline Elevator

Hi Everyone, I built the Incline Elevator but I am having trouble with the electronic controls. I am using the picture in the catalog 1975-39004 page 15. I tried a few wiring circuits but have not got it to work correctly. The way I see it operating is as follows. It should stop when it reaches each...
