Custom LM337 Active Servo Precision Adjustable Power Supply Board Panasonic Active Servo Power Supply

LM317/337 Active Servo Precision Adjustable Power Supply Board

Power supply voltage: dual AC 12V-24V, three tap transformer with a power not less than 20W

Output voltage:+- Dual 5V - Dual 18V adjustable (maximum voltage determined by transformer)

Circuit board specifications: 7.5CM in length, 7.5CM in width, and 4CM in height (radiator height)

The installation size of the screw hole is 67MM * 66MM

1.6mm thick FR4 epoxy board, designed with a location for installing small metal seal LM317-337.

This circuit uses a brand new LF353 dual operational amplifier as the servo core, a brand new imported (ON) three terminal voltage stabilizing integrated block LM317, LM337 adjustable voltage stabilizing output, voltage adjustment range+-9 to+-15V, this circuit includes 4007 rectifier tubes, BC 2200UF/50V × 2, 100UF × 2, 10UF × 4, BC 0.1UF × 2 as filters,

Three terminal voltage regulator integrated block with aluminum heat sink, high power output accuracy and good stability

Active servo power supply is designed specifically for the front-end of audio circuits, with low internal resistance, stable output voltage, low noise, and can effectively ensure the highly stable operation of chips such as NE5532, OPA2604, AD827, OPA627, and improve transient and high-frequency characteristics.

The main filtering capacitor can be installed with a maximum diameter of 25MM.
