LM317 LM337 Active Servo Adjustable
Regulated Power Supply Bare PCB Board
Description:
This is Bare PCB, not contains any other electric components.
Power Supply Voltage: Dual AC 12V-24V (Suggest power is not less than 20W three-tap transformer)
Output Voltage: Double ±5V ~ ±18V adjustable (The highest voltage is determined by the transformer)
PCB Size: 75mm x 75mm x 1.6mm (L*W*H)
FR4 epoxy boards, board design can be installed statuette seal LM317-337 position.
This circuit with a new dual op amp LF353 make servo core, new import (ON) three-terminal regulator blocks LM317, LM337 adjustable voltage regulator output, voltage adjustment range ±9 ~ ±15V, this circuit containing (ON) MUR120 rectifier, BC 2200UF/50Vx2, 100UFx2,, 10UFx4, BC 0.1UFx2 as a filter.
Three-terminal regulator blocks the installation of an aluminum heat sink, high power output accuracy, good stability.
Active Servo power supply is designed for Pre-amp audio circuit design, small internal resistance, output voltage stability, low noise, can effectively guarantee a high degree of stability NE5532, OPA2604, AD827, OPA627 chips, etc., to improve the transient characteristics and high frequency characteristics.
Maximum main filter capacitor can be installed 25MM diameter.
