Zs= Output/Secondary impedance Example: Input impedance = 8, Output impedance = 40 Np/Ns=0.4472 Ns/Np= 2.2361 Hence Secondary turns are 2.2361 times more than the Primary turns.i.e Ns= 2.2361 x Np Get the RF Calculator App Download the RF Calculator App on Android or iOS devices...
Hence for an ideal transformer, the output current varies as inversely proportional to the voltage. In a step-up transformer, the primary voltage can be stepped up based on the turns ratio but the load current capability of the same at the stepped-up voltage will reduce as the inverse of t...
So Vrms is lower than the Vpeak required at the regulator's input, and with low output current requirements, may be lower than regulator Vout. Why is Vrms negative and almost 1000? The calculator does this when Load Current exceeds the capability of the selected Superpower type. What kind ...
Transformer full load current = 1000 / (1.73 2× 480) = 1203 Amp. Short circuit current at TC secondary (Isc) = Transformer full load current / Impedance Short circuit currentat TC secondary = 1203 / 5.75 = 20919 Amp Maximum kVA of TC at rated Short circuit current (Q1) = ...

Output of the auxiliary winding is 10.2 V. Inductance is for the primary, measured at 150 kHz, 0.1 Vrms, 0 Adc DCR for primary is per both windings connected in parallel, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator. Leakage inductance is for...
and delivery on time. Especially Josh long was helping me out deciding which transformer to use. I purchased a transformer 30KVA step down from 240V to 208V 3 phase. The transformer has 7 tap inside which you can choose or adjust exactly output Voltage. Our voltage input 252V, 3 phase wi...
The transformer has 7 tap inside which you can choose or adjust exactly output Voltage. Our voltage input 252V, 3 phase with high leg 208V phase B. But our new machine need to run at 200-208 Volts. Thank you so much! super highly recommended. Bao Nguyen I spoke with Josh Long and ...
