120v transformer to 34v

[peterward]

So I purchased a control board that has a Chinese transformer. Input 120v, 50/60Hz 1.0A...Output 34v (a line with 3 dashes under it) 1.17A. It has two batteries that are kept charge by this transformer. Do I need to replace this with the "exact" transformer? Or can someone tell me what I "can" use that will work? thanx

Yes you need the same one volatge and current, also take note of the connector polarity.

The line with 3 dashes means DC. 34 VDC is unusual. You will need something greater than 1.17 Amps. If you get stuck, you could find a 12 or 24 VDC adapter and make a box to house one of these: **broken link removed**

You'll likely need a voltmeter to adjust it.

The power output of the adapter used must be greater than (1.17 A * 35 V) + 10 to 20%, so a 2A 24 VDC supply will work with the above board to boost it to 34 VDC.

work frequency is 50-60Hz, it is lamination transformer, power is 120*1=120W, for the low frequency transformer, 120W is very big, can you again confirm electical parameteres?
