Rowe AMI G 120

Hi,

Can someone tell me what is the DC voltage for the mechanism section and what is the max current . I think it is 32 volts but would like it confirmed. The transformer in my machine has been replaced with a transformer that has 50 volt output. It seems that a large resistor was used to drop the voltage after the rectifier but it has just burnt out from a short somewhere and as there is no marking to indicate its ohm value I will need to re-calculate or find a closer matching transformer. There are other problems but I will need to fix the power issue and cause of the short first before I continue.

Would like to hear from anyone who is familiar with this model and its faults.

Hello Greg

The voltage should normally be 28 volts. A value between 25 and 30 volts will be ok. It is to be expected with a current of about 2A. Since power consumption varies widely, reducing the voltage with a series resistor is not recommended.

Thank you. I will probably need to have a transformer wound. Would the original transformer have had a 20 volt output to achieve the 28 volts DC.

Hello Greg

I think you can use a standard transformer with 24 volts output. The DC voltage is therefore a little too high (about 32 volts), but can be tolerated. Perhaps you can also find a standard transformer with 20 or 22 volts.
