LM317 LM337 AC-DC Adjustable Regulated Power Supply Module Dual AC to DC Converter Voltage Stabilizer

Description

LM317 LM337 AC-DC Adjustable Regulated Power Supply Module Dual AC to DC Converter Voltage Stabilizer 1.Descriptions: It is a DC adjustable power supply board.The rectification part uses 4 independent rectifier diodes,each of which has an anti-interference capacitor in parallel,which can prevent useful signals (usually high-frequency signals) and power frequency signals (50 Hz) from generating mutual modulation on the rectifier diodes.As a result,an interference signal is generated,which interferes with the normal operation of the machine,eliminates the "modulated AC sound",and eliminates the source of interference for the subsequent circuits from the source.The PCB LAYOUT design of the circuit board,the entire circuit board is grounded at one point.Even if multiple instruments and lines share a power board,there will be no power ground loop,and no AC sound will be generated without the ground loop.Solve the ground loop problem from the source.2.Feature: 1>.Positive and negative dual AC power supply 2>.It supports short circuit protection 3>.It supports overcurrent protection 4>.It supports overheating protection3.Descriptions: 1>.Product Name:DC Adjustable Power Supply Board 2>.Input Voltage:Three-wire AC dual below 28V 3>.Output Voltage:DC 1.25V~30V 4>.Output current:1.5A 5>.Linear Adjustment Rate:0.01% 6>.Load Regulation:0.1% 7>.Ripple Suppression Ratio:80dB 8>.Work Temperature:-25℃~85℃ 9>.Work Humidity:5%~95%RH 10>.Size:70.5*51*30mm4.Package: 1>.1pcs DC Adjustable Power Supply Board
