SINGLE PHASE CONTROL TRANSFORMERS

In case you purchase a multi-tap secondary transformer, please follow the table below to get the max. rating available on each secondary voltage:

Secondary 12/24/48V Secondary 110/127/220V

Sec.V	12V	24V	48V	Sec.V	110V	127V	220V

2500VA	625VA	1250VA	2500VA	2500VA	1250VA	1437VA	2500VA
3000VA	750VA	1500VA	3000VA	3000VA	1500VA	1725VA	3000VA

Tables shown are just an example. Ratings can always be calculated according to these instructions and the voltage indications on the label of the transformer

The label on the transformer shows the highest applicable rating on the secondary side. You can approximately obtain the max. rating for each secondary voltage simply multiplying the voltage by the fuse rating.

e.g.: 500VA transformer sec. 12/24/48V fuse 10A

The max available power on 24V output is: VA= 24(V) x 10 (A) = 240VA

Please note that the max rating is available at the highest primary voltage only. Otherwise you have to derate the transformer according to the primary voltage connected:

e.g.: 500VA transformer Pri: 127/220/380/460V Sec.: 12/24/48V @ 10A

Primary used: 380V Secondary used: 48V

Max rating (VA)= 500VA x ( 380 (V) / 460 (V) ) = 413VA
