DC Power Supply UNI-T UTP3305-II

The UTP3305-II laboratory power supplies are branded power supplies with three independent channels from the UNI-T manufacturer. The sources contain a classic linear transformer and in channels CH1, CH2 they allow operation in the mode of setting the constant output voltage in the range of 0 to 32V or in the mode of constant output current 0 to 5A. Channel CH3 provides a constant voltage of 5V at the output and has overload protection when current consumption 3A is reached. Channels CH1 and CH2 can operate independently of each other, or they can be internally connected in series or in parallel, then supply voltages from 0 to 64V / 0 to 5A or 0 to 32V / 10A. The laboratory power supplies have four LED displays that display voltages and currents simultaneously, with an accuracy of 4 locations in each of the CH1 and CH2 channels. The source contains a temperature-controlled fan, long-term thermal overload of the transformer of the laboratory source is monitored by a sensor, which switches off the source when the limit value is reached and switches it on again after cooling. The device is CE certified.
