DC power supply UNI-T UTP3305-II

This product comes with a 3-year warranty.

The UTP3305-II 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 channels CH1 and CH2 allow operation in constant output voltage mode in the range from 0 to 32V or in constant output current mode from 0 to 5A. Channel CH3 provides a constant output voltage of 5V and has overload protection when the current consumption reaches 3A. CH1 and CH2 can operate independently of each other, or they can be connected internally in series or in parallel, then provide voltages from 0 to 64V / 0 to 5A or from 0 to 32V / 10A. The laboratory power supplies have four LED displays that show voltages and currents simultaneously, with an accuracy of 4 digits in each of the CH1 and CH2 channels. The power supply contains a temperature-controlled fan, and the long-term thermal overload of the laboratory power supply transformer is monitored by a sensor, which shuts down the power supply when the limit value is reached and restarts it after cooling. The device is CE certified.
