Product description format_size zoom_out zoom_in

  In amateur radio practice, a power supply is often needed that is simple, small in size and has a high load capacity. This kit will allow you to assemble an adjustable voltage regulator with a wide range of output voltage (5…27V) and output current up to 20 A.

Specifications:

  • Input voltage min, V.........……..…8
  • Input voltage max, V.....…..........30
  • Output voltage, V.........……….5...27
  • Output current, A......................….........up to 20
  • Overall dimensions, mm ……….90х46х24

Device Assembly Recommendations

  Transistors T1-T3 must be installed on the radiator evenly over its entire area. The dimensions of the radiator are calculated based on the maximum power dissipated by the transistors, which should not exceed 150 W.
Pq=(Uin-Uout)*Iload where:
Pq - transistor power dissipation
Uin, Uout - input and output voltage, respectively
Iload - load current
 
  The heatsink area is calculated at the rate of 20 cm2 of dissipated power per 1 watt. The thickness of the radiator base must be at least 5mm.
  If the device is used at maximum loads, it is necessary to install a forced air fan on the radiator.
  For normal operation of the device, the input voltage must be greater than the output voltage by at least 3 volts.
  The power tracks on the printed circuit board need to be reinforced with solder.
