Laboratory power supply 2x0-32VDC 2x5A, 4xLED tabloo

The UTP3705s by Unit is a double laboratory power supply, i.e. with 2 voltage outputs. The two output channels CH I and CH II of the UTP3705s power supply are symmetrical and enable smooth voltage adjustment in the range from 0 to 32V and current efficiency up to 5A in each of these channels. Voltage and current regulation in CH I and CH II is independent, i.e. in the first channel we can set the output voltage value of 5.60V, and in the second channel, CH II 32.0V. The maximum current efficiency of the UTP3705s power supply in CH I and CH II channels is 5A in the entire range of the output voltage. The UTP3705s laboratory power supply enables the CH I and CH II outputs to be connected in parallel or in series in order to increase the current efficiency or increase the output voltage range. Parallel connection of the CH I and CH II outputs of the UTP3705s power supply sums up its output current, which in practice gives us 10A of the maximum output current (5A from the CH I channel + 5A from the CH II channel). In the case of a series connection of CH I and CH II, the current efficiency remains at the same level, i.e. 5A, while the voltage values ​​from both channels add up, resulting in a power supply with adjustable output voltage from 0V to 64V. The third option to connect the independent outputs of the UTP3705s power supply is to obtain symmetrical voltage: the middle green terminal is GND. In CH I we have a free terminal (+) and we have an output of regulated positive voltage from 0 to 32V. In the CH II channel we have a free terminal (-) and there is a negative voltage output that can be analogously adjusted in the range from 0V to -32V. Double, symmetrical voltage is used min. in analog technology to supply operational amplifiers, power amplifiers. The design of the UTP3705s power supply is based on a transformer, which ensures its more stable and failure-free operation compared to structures based on an impulse converter. The UTP3705s power supply is equipped with four 7-segment LED displays, shining red for voltage (voltmeter) and green for current (ammeter).
