It works with a constant voltage in the range of 10-50 V and is designed to regulate the power in various devices, for example, heaters or lamps that have the maximum consumed current - 40 A.

The device body is fastened with latches, but be careful because they quickly break. Therefore, open very carefully. Inside there is a board and knob of the regulator.

The board is made of two-way glassstolite, and its connection is carried out using a powerful terminal bar.

In the case there are slots for ventilation, but there is little sense from them, since almost all the space is the fee itself.

The PWM frequency of the regulator is 12 kHz. If you start adjusting the output power, then the actual frequency will be 12-13 kHz. If necessary, you can reduce the frequency. To do this, you need to fall parallel to the C5 desired condenser. But it is not worth increasing the frequency, because there will be a switting loss above.

A variable resistor has an additional switch in the extreme left position. More on the board additionally is the Red LED, which turns on when the regulator works,

As with most of the power regulators, adjustment is carried out with a minus conductor.
