WebJul 23, 2024 · So you have a 75 VA control transformer with a 24 volt secondary. VA ÷ VOLTS = Maximum amp load, 75 / 24 = 3.125 Amps. I would fuse the secondary at 3.0 Amps slightly below the VA rating. If you want to fuse the primary side then 75 / 120 (assuming 120 VAC mains supply) = 0.625 Amp so I would start with a 0.5 Amp fused primary. WebChecklist Transformer Size Calculator When sizing a transformer, you need to know the kilovolt-amps (KVA) that your machine requires. This tool will allow you calculate the KVA that you need. This tool only evaluates common voltages for North America (ie. 24v, 120v, 208v, 240v, 480v, and 600v). process stderr
