The UDP3305C programmable DC power supply is a cost-effective, four-channel independent laboratory power supply from UNI-T. The power supply contains a classic linear transformer, and in channels CH1 and CH2 it allows operation in constant voltage (CV) mode within the range of 0 to 30V or in constant current (CC) mode from 0 to 5A. Channel CH3 provides a constant output voltage with the option to select a level of 1.8V, 2.5V, 3.3V or 5.0V and features overload protection when the current draw reaches 3.2A. In addition, there is a USB connector on the front panel, which serves as channel CH4 and can be used to charge, for example, a mobile phone at 5V/2A. Channels CH1 and CH2 can operate independently, or can be connected internally in series or in parallel, in which case the power supply provides a voltage of 0 to 60 V or 0 to 50 V or 30 V/10 A. The laboratory power supply features an EBTN display with 6 high-precision indicators that simultaneously display voltages, currents and power in both CH1 and CH2 channels to 4 decimal places. The power supply has programmable parameters. It features 5 memory slots for easy storage and recall of preset modes and a lock button to prevent unwanted changes to the parameters. On the rear of the power supply housing are USB-Device and RS232 connectors and a DIGITAL I/O interface for remote control of the power supply. Using the supplied software, it is possible to record and display the consumption or load characteristics of the connected load in real time on the connected PC in an Excel spreadsheet or a graph, and it can communicate with the computer via SCPI communication commands. Regular calibrations can be performed via the software. The power supply contains a temperature-controlled fan; the long-term temperature overload of the laboratory power supply’s transformer is monitored by sensors which shut down the power supply when the limit value is reached and restart it after cooling.

UNI-T UT303C+ Infrared Thermometer This product comes with a 3-year warranty. The UT303C+ infrared thermometer can quickly and accurately determine surface temperatures between -32°C and +1300°C by measuring the infrared energy radiated from the target surface. For easier and more intuitive targeting of the device onto the target surface, a unique ring laser targeting indicator is incorporated, which is offered exclusively by Uni-Trend for its devices. The ratio of distance to the diameter of the measured surface is 30:1 with this instrument. It is possible to preset the emissivity of the measured surface within the range of 0.1 to 1.0 and to save the 5 most frequently used emissivities. Preset functions and measured values are displayed on a clear, high-contrast colour EBTN display, whilst limit values are indicated by red, green and blue LEDs on the top of the device and an audible alarm. You can set the system time and schedule repeated measurements in the future at a set interval, and save up to 99 measured values. The measurement time is also stored for each saved value. For these measurements, you will use the built-in standard socket for mounting on a tripod. The temperature measurement time is up to 250 ms in 95% of cases. It is possible to set minimum and maximum value limits, and measurements outside this range are indicated by an audible and visual signal. It is possible to display minimum, maximum and average temperatures, as well as deviations from the average (MIN, MAX, AVG, DIF).
