IT1083CP Hi-Fi Linear Regulated PSU Board – High Power Adjustable, Single/Dual Output

       The ground wire of the two linear regulator boards isIt is completely independent and separated, so it can also be connected to a double-bridge positive and negative power mode, or a 2-way positive voltage mode. The display board is not brought, and it needs to be bought independently. 1 piece is 8 yuan.

Pay attention to one key point. In order for the voltage to be stable enough, the power supply voltage after the input voltage rectification must be 3V or more higher than the output to have a good effect. Some customers input 10V and adjust to the output 12V. It is not practical to evaluate instability. As long as the pressure difference is above 3V, with and without load, the error will not exceed 1%

The materials used and matched are far better than other peers, such as Phoenix radiator, US BI adjustable resistor, Germany WINA Japan ELNA-AUDIODouble-sided PCB (mostly cheap single-sided PCB)The price is also slightly higher than that of its peers, but the improvement in effect is definitely positive

Not all devices use such a high current, but because the output current is sufficient, the internal resistance of the power supply is very low. Even devices that consume 100MA have a very good positive improvement, abundant capacity, and significantly enhanced low-frequency bouncing power. Suitable for electronic tube filament circuits, digital turntables, portable DACs and other equipment

parameter

DC input: 2.5-35 V;
AC input: 2.5-27 V;
Output DC: 2.5-35 V;
Maximum current: 7 amps;
Input and output minimum pressure difference: 2.5 volts (LT1083 is not suitable for large voltage difference operation, input and output are preferably within 10V, 3-5V is best, this is a linear IC, power consumption is proportional to the pressure difference, the maximum pressure difference cannot exceed 20V)

Dual PCB size: 96 × 71mm Single PCB size: 79 × 46mm

Weight: about 124g Weight: about 119g

*** The board can also be compatible with LM317 LT317 LT1085 LT1084 LT1086 and other voltage regulators

The LT1083 is a high-power linear three-terminal regulated integrated circuit produced by Linear Technology, with an output current of up to 7A. It can operate under pressure differential conditions as low as 1V; it can provide the guaranteed minimum pressure differential through an on-chip correction circuit under various current levels, and can adjust the output voltage accuracy to 1%. Its voltage adjustment rate is 0.015%, the load adjustment rate is 0.01%, and it has thermal power limit protection

7A current high-power output, power supply production, optical drive or bile filament, etc., which requires high current, can also be used in power amplifier front-stage power supply, and can even be used in some low-power power amplifier circuits (pay attention to heat dissipation), IC with overheating and overload protection, perfect protection

PCB uses military double-sided, and the quality is far from comparable to those cheap so-called A material B material list panels
