AUDIO-GD PSU-2017 Neutral Class A Power Supply -/+ 9V 30mA

This AUDIO-GD PSU 2017 Class A low noise power supply module allows you to obtain 2 regulated voltages DC +V / -V with an output current of 30mA.

The benefits of class A diets are well known :

They have a very high input impedance and a low output impedance that avoids the disturbances of traditional audio power supplies. The run-up times are among the best.

The design in Class A allows to provide a clean voltage, bringing neutrality, micro dynamics on small signals.

Its as convincing as a battery power supply without the problems of charging and discharge.

This very low noise power supply is especially designed for HIFI devices requiring fast mounting on small electrical signals such as:

• The DAC
• Mono and stereo analog buffers with discrete transitors or OPAs
• Audio preamplifiers
• Gain stage without counter reaction
• DAC AUDIO GD DA M1 R2R 24bit 3072K DAC modules

Technical caracteristics :

• Regulated power supply in pure class A
• Originally designed for 30 mA standby current
• AC IN: Connection of AC transformer VAC
• V-OUT: Negative voltage output VDC
• V+OUT: Positive voltage output VDC
• GND: fully balanced card with two separate outputs

Spacers

• Included x4
• Already mounted
• M3 x 10mm

Dimensions and weight :

• Dimensions : 98 x 65 x 45 mm (foot without)

NOTA BENE ! ATTENTION :

Class A power supplies require some precautions when operating them:

• Class A power supplies must not remain unloaded while in operation.
• Always connect a circuit on top, never leave them empty.
• The power supplies in class A emit heat, provide a box with openings accordingly.
• The board with two completely separate circuits must be connected between the two GND groundings when using both sides together.
