UNI-T UDP4303S lab power supply
Details
The UNI-T UDP4303S is a high-end programmable DC linear power supply. This power supply has a total power output of 297W. The first two channels have a voltage range of 0-32V, the third channel has a voltage range of 0-15V and the fourth channel has an voltage range of 0-6V. This UDP4303S has a remarkably high resolution and accuracy of 1mV/1μA and <0.03%+8mV <0.15%+5mA, respectively. The device features 4 independent isolated channels, which all support low current mode and remote sensing, which compensates for voltage loss, ensuring precise voltage delivery.
Channels 1 and 2 support internal series and parallel connections as well as channel tracking, allowing them to duplicate each other, so changing the settings on one channel can automatically adjust the other. Furthermore, all channels feature waveform display with an 8kSa/s current sample rate.
The device also features USB device/host interfaces as well as RS232 and LAN for programming. Finally, the UDP4303S comes equipped with a 4.3" LCD screen and a user-friendly interface, making it easy to operate.
The default 3-year warranty can be extended to 5 years by registering your instrument.
