Laboratory power supply UNI-T UTP3303-II

Product detailed description

We offer a 3-year warranty on this product. The UTP3303-ll laboratory power supplies are branded power supplies with three independent channels from the manufacturer UNI-T. The power supplies contain a classic linear transformer and in the channels CH1, CH2 they allow to work in the mode of constant output voltage setting in the range of 0 to 32V or in the mode of constant output current 0 to 3A (or 0 to 5A in the case of the type UTP3305-II). Channel CH3 provides a constant output voltage of 5V and has overload protection when the current draw reaches 3A. Channels CH1 and CH2 can operate independently, or can be interconnected internally in series or parallel, then supply a voltage of 0 to 64V/0 to 3A (5A) or 0 to 32V/6A (10A). The laboratory power supplies have four LED displays that show voltage and currents simultaneously, accurate to 4 digits in each of the CH1 and CH2 channels. The power supply contains a temperature controlled fan, long-term temperature overload of the laboratory power supply transformer is guarded by a sensor which switches the power supply off when the limit is reached and back on again when the transformer has cooled down. The device is CE certified.
