60W Encapsulated Single Phase audio toroidal transformer Low Frequency Power for Audio Ampllifier

ZXY-60W is a 60W toroidal (ring-type) low-frequency power transformer built for audio power amplifiers and other low-noise audio equipment. The gapless toroidal core and evenly wound pure copper windings give high efficiency with very little induced vibration, so the transformer adds almost no hum or mechanical noise to the audio chain.

The 50/60Hz primary covers 110V, 220V and 230V mains (the reference unit is wound 0-230V), and two independent secondaries - 18V-0-18V (BLU-BLK-BLU) and 0-18V (GRN-GRN) - provide the split and single rails that analog amplifier stages normally need. At roughly 95mm outside diameter by 45mm high and about 1.1kg, it mounts through a single center screw on the supplied plate and hardware, which keeps installation and service inside an amplifier chassis simple. Other output voltages (12V, 15V) and other ratings across the 6VA-1000VA range are available on request.
