Product Description

1300VA toroidal transformers for professional amplifier
Primary: 0-----220V
Secondary: 0-----16V 1A
0-----23V 1A
0-----23V 1A
75V--0V---75V 4A
75V--0V---75V 4A
Power: 1260VA
Weight: 8.7kg
Size: OD?160mm, H?90mm
Rated no load current?80mA (220V 50Hz)
Primary lead wire with 40mm white fibre tube
Black epoxy resin: primary lead wire to top side, 11mm hole in center.
Use dia. 100mm metal plate and rubber plate in bottom side.
Toroidal transformers 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
Manufactured to Class B 130oC
Class Max Temperature Max Temp Rise
A 105oC 65oC
E 120oC 80oC
B 130oC 90oC
F 155oC 115oC
Toroidal transformers losses do not exceed 2.5watts per kilo (core weight X 2.4) / input voltage
