The ground wires of the two linear voltage regulation boards are completely independent and separated, so they can also be connected in a dual-bridge positive and negative power supply mode, or used in a 2-channel positive voltage mode.
Pay attention to one key point: for the voltage to be sufficiently stable, the rectified power supply voltage of the input must be 3V or more higher than the output to achieve good results. As long as there is a voltage difference of at least 3V, the error will not exceed 1% with or without a load。
Parameter
DC input: 2.5-35V;
AC input: 2.5-27V;
Output DC: 2.5-35V;
Maximum current: 7A;
Minimum input-output voltage difference: 2.5V (LT1083 is not suitable for operation with large voltage differences. It is best to keep the input and output within 10V, preferably 3-5V. This is a linear IC, and its power consumption is directly proportional to the voltage difference. The maximum voltage difference should not exceed 20V)
Dual-channel PCB size: 96×71mm
Single-channel PCB size: 79×46mm
Weight of the dual-channel version: approximately 124g
Weight of single-channel version: approximately 119g
