AC-DC LM317 LM337 Adjustable Voltage Regulator Power Supply Positive Negative Dual Power Step Down Module Buck Converter

Product selling point:
1. Using high-quality materials, product quality is guaranteed
2. The rectification part adopts 4 independent rectification diodes, each diode is connected in parallel with an anti-interference capacitor, which can prevent useful signals (usually high-frequency signals) and power frequency signals (50 Hz) from generating mutual modulation on the rectification diodes, As a result, interference signals are generated, which interfere with the normal operation of the machine, eliminate "modulated hum", and eliminate interference sources for the following circuits from the root.
3. The entire circuit board is grounded at one point. Even if multiple instruments and lines share one power board, there will be no power ground loop. Without a ground loop, there will be no hum. Solve the ground loop problem from the source
4. Small appearance, beautiful arrangement of components
5. Wide range of applications, the product has output short-circuit protection, over-current, over-heat protection

Product parameters:
Input: AC0-28V (no more than 28V!)
Adjustable output voltage down to 1.2V. Guaranteed 1.5A output current.
Typical linearity adjustment is 0.01%. Typical load regulation is 0.1%. 80dB ripple rejection ratio.
Voltage output range: DC1.25V-30V, positive and negative voltages are continuously adjustable
Tips: Due to the instability of supply, different brands of high-quality capacitors will be used.
