Transformer Sizing
If your application requires a transformer, use the following table for sizing the KVA rating. The values in the table are based on “worst case” power usage and can be considered a conservative recommendation. You can
Drive/Motor Combination | Suggested KVA Rating |
1.0 | |
|
|
1.0 | |
|
|
1.2 | |
|
|
1.7 | |
|
|
2.3 | |
|
|
3.0 | |
|
|
Transformer output voltage drop may become a limiting factor at motor speeds and loads near maximum ratings. Typically, higher KVA transformers have lower voltage drop due to lower impedance.
