LT1083-85 or LM317-38 Adjustable Regulated Power Supply PCB

Features:

• Size: 106 * 46 * 2mm (L*W*TH)
• LT1083CP (LM317 / LT1086) precision high current adjustable power supply, 2mm thick double-sided gold-plated PCB
• You can choose LM317 / LM350 / LT1083CP / LT1084CP / LT1085CP / LT1086CP, etc., They can be installed directly on the board.
• From the regulator performance and power considerations, it is recommended to input AC slightly greater than the required output DC can be. For example, DC9V out, available AC10-12V into (please note that the use of pressure to change the freedom).

Note: The output voltage value Uo = [(VR / R) +1] x1.25V.

Assembly techniques:

① independent adjustable DC1.3-35V high-precision power supply, two groups of PCB can be used to form positive and negative symmetrical or positive and negative asymmetrical power supply (transformer to be independent winding), the need for higher output, please pay attention to capacitor voltage.
② for the drive or dampers filament and other large current occasions, can also be used in the power amplifier before the power supply, 7.5A current output capability can even be used in some low-power amplifier circuit (pay attention to heat). Not all devices use such a high current, but the device output current is sufficient, the power supply resistance is low. Even in the consumption of 100mA on the device, there are very good positive increase, abundant ability, low frequency jumping significantly enhanced, suitable for tube filament circuit, digital dial, portable DAC and other equipment
③ unique capacitor mounting position (can be installed within the large 35mm diameter electrolysis), can adapt to most of the Japanese / European Department of 2 feet / 3 feet / 4 feet / 5 feet of capacitance.
④ rectifier can adapt to TO-220 or Motorola wheel tube, the general IN4007 or IN5408 less mention.
⑤ voltage adjustment with precision multi-turn adjustable resistance, leaving the resistance of the installation bit (from the performance considerations we recommend the need to adjust the voltage after the fixed resistor instead).
⑥ taking into account the use of each customer is different, small current places do not need heat. So the finished board will not deserve the radiator, by the user according to their own needs to choose. The PCB for the board side installed thermal design, the basic can be appropriate to install a variety of radiators.
