Using genuine LM317/LM337 for voltage stabilization, the highest input dual AC voltage is dual 22V, the output voltage can be adjusted in the range of plus or minus 1.25-30V, and it has a thick heat sink. It can be used as the front-end power supply for NE5532, OP275, AD826, etc., or various AD circuits or sensors that require positive and negative power supplies to provide low internal resistance, low noise, and low ripple power.

Input voltage range: dual AC voltage AC5V-24V

Output voltage range: positive and negative DC1.25V-30V (continuously adjustable)

Output current range: Maximum continuous working current <700mA (pressure difference does not exceed 10V), when the pressure difference exceeds 10V, please ensure that the output current is <500mA

Terminals: AC input terminal (no polarity), DC output terminal V+ output positive, DC output terminal V- output negative, GND is the common terminal

Dimensions: length 50mm, width 45mm, height 29mm

Operating temperature range: 0°C-100°C (in order to prevent over-temperature damage, you can increase the heat dissipation by yourself or use other active heat dissipation methods)
