30w Dual 18v + Dual 12v 115-230vR Type Power for HIFI Preamplifier DAC Decoder Headphone Amplifier
Product introduction:1: iron core and oxygen-free copper enameled wire are used.
2: Precision manufacturing, low noise, low loss, low magnetic leakage, low variable power, and reliable performance.
3: Independent and shielded wire output!
Parameters:Size: 79×68×39 (mm)
Weight: about 0.5 kg
30W dual 18V + dual 12V (0V-115V-230V)
0-18V (two purple wires)
0-18V (two white wires)
0-12V (two orange wires)
0-12V (two gray wires)
0V (black wire) -115V (yellow wire) -230V (blue wire) -SCN (a yellow-green wire primary shield wire)
Remarks:A yellow-green wire is the primary shield wire----add welding piece to ground (chassis ground)
If you connect black wire and blue wire when connecting to 230V, the 115V yellow wire should be covered with shield or cut off.
Description:Because of the production load voltage design, the voltage will be higher when measured with no load. When the mains power is 236V, the voltage measured is 18V. The voltage measured with no load is 22.3V. The voltage measured with no load is 12V. The voltage measured with no load is 14.9V. Please check it out before placing an order.
Primary:0V-115V-230V international voltage SCN ground wire
Secondary:Dual 18V (0.6A) + Dual 12V (0.35A) 4 wires
