Product Description

60VA toroidal transformer use for civil amplifier
Input: 0-----110V
Output:25V--0V----25V 1A
5.6V-0V----25V 0.5A
Power: 60VA
Size:OD?85mm, H?40mm
Rated no load current:?30mA
Test: 3.5kv 5mA 5S between primary and secondary
Toroidal transformer frequency: All of our transformers are designed for 50/60Hz.
Toroidal transformer voltage regulation: this is the power lost (heat) in the normal operation of the transformer.
Voltage regulation=(no load voltage-load volatge)/no load voltage*100%
Example: no load voltage 18v, load voltage 17v. voltage regulation=(18-17)/18*100%=6%
A regulation of 6% means the transformer is 94% efficient
