Small but smart ... ;-)
It belongs to the hobby-class equipment, but it is well "charged" functionally.
It is characterized by good voltage stabilization. Lightweight and efficient, suitable for service and laboratory work.
Compact stabilized power supply with adjustable output voltage from 0 to 15 V and output current from 0 to 1 A.
Classical circuitry based on a step-down transformer.
In case of short circuit, the buzzer sounds as an audible alarm. The protection works in automatic mode, when the short circuit is eliminated, the power supply returns to the previous mode.
Built-in voltmeter for measuring DC voltage. The measured voltage is indicated on the LED indicator.
The toggle switch on the front panel (above the terminals) switches the power supply to the voltmeter mode, the measured voltage must be applied to the output terminals of the device.
On the front panel there is a USB connector with a fixed voltage of 5V.
The dial indicator is convenient for observing the dynamics of current consumption by the load.
Bar indicator of the radiation power of the transmitter of a GSM-range mobile phone. Located on the left side of the voltage indicator, it is triggered automatically when the radiation of a nearby mobile device during an outgoing call.
The dimensions and weight of less than a kilogram allow it to be classified as portable (!!!) devices, which is unusual for laboratory sources.
The set includes cords for connecting mobile phones and test leads-probes like those of multimeters.
Recommended for beginner radio amateurs, and also as an auxiliary power source in the workplace of a mobile phone repairer.
