Radioconstructor, a kit for assembling a laboratory unipolar power supply unit with adjustable output current and voltage.

Can be used by both experienced and novice radio amateurs to improve their skills in reading circuits, assembling circuits, soldering, etc. This constructor allows you to assemble a power supply using a circuit, a printed circuit board, mounting and electronic components that come with the kit. It is assembled intuitively from the marking and ratings on the circuit board and is made by mechanically connecting the elements and soldering.
A properly assembled device does not need adjustment.

Key Features:

Input voltage: 24 VAC
Output voltage: DC 0-30V
Maximum input load: 3 A
Output load: 2 mA to 3 A
Output voltage ripple: 0.01%
PCB dimensions: 85 x 85 x 1.5mm
Set weight: 80 g

The board provides a place for mounting a linear stabilizer L/LM 7824 for 24V, which, if necessary, can be replaced with L/LM 7812 for 12V power supply of the fan of the forced cooling system of the radiator.

Pay attention! When operating at maximum current or at any load for a long time, the power transistor must be installed on a forced air-cooled radiator. The radiator area for maximum capacities must be at least 600 cm2. You can choose a radiator in our catalog here or here . The fan can be bought here .
Pay attention! The circuitry of this device assumes power only from an alternating voltage source (transformer). It is not suitable for DC UPS power supply.
