Product Description

580VA toroidal power transformer for civil amplifier
Input: 0-------220V
Output: 0-------9V 0.5A
16V----0V---16V 0.5A
56V----0V---56V 5A
Power: 580VA
Size: OD?84mm, H?130mm
Primary lead wire with white 30mm firbe tube
Rated no load current?100mA
3.5kv 5mA 5s between primary and secondary
Safety isolating toroidal transformer
Toroidal power transformer frequency: All of our transformers are designed for 50/60Hz.
Toroidal power 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
Manufactured to Class B 130oC
Class Max Temperature Max Temp Rise
A 105oC 65oC
E 120oC 80oC
B 130oC 90oC
F 155oC 115oC
