The 32 V ceiling and 6 A current capability cover most service-shop and bench needs (powering boards under repair, driving solenoids and small motors, sourcing test current for relay coils, validating regulated subsystems against their input rails), and the linear topology keeps output ripple under 2 mVrms.\u003c\/p\u003e\n\u003cp\u003eAn auxiliary fixed 5 V \/ 2 A output handles logic-side power on a board under test while the main channel sources the load — useful when characterizing a regulated subsystem against its input rail.

The UDP1306C is a single-channel value-tier instrument (1 main adjustable + 1 fixed 5 V \/ 2 A auxiliary). The UDP3303C is a three-channel UDP3000C-platform supply (CH1 + CH2 adjustable + CH3 logic-rail selector). Choose UDP1306C if you need one programmable rail at this price point; choose UDP3303C if you need the multi-channel CH3 logic-rail flexibility on the higher-tier platform.\u003c\/p\u003e\n\u003ch3\u003eDoes the UDP1306C have LAN?\u003c\/h3\u003e\n\u003cp\u003eNo. The UDP1306C's data interfaces are USB-Device and RS-232 only. The Digital I\/O pin pair on the back panel handles hardware ON\/OFF — useful for external interlocks but not for data communication. For LAN with LXI\/web interface, the UDP3000S series adds it on the higher-tier multi-channel linear platform.\u003c\/p\u003e\n\u003ch3\u003eWhat is the auxiliary 5 V \/ 2 A output for, and how is it different from the front-panel USB charging port?\u003c\/h3\u003e\n\u003cp\u003eThe auxiliary 5 V \/ 2 A output is a fixed-voltage rail on screw terminals at the back panel — for wiring into the DUT to power logic-side circuits while the main 0–32 V \/ 6 A channel sources the rail you're tuning. The auxiliary rail has its own short-circuit and over-voltage protection on the rail itself, so a fault on the logic side won't take down the main bench supply. The front-panel 5 V \/ 2 A USB-A port is a separate, independent receptacle for charging a phone or powering a USB device — charging only, no data lines.

Five preset storage groups keep frequently used configurations available for fast recall. For complex programmable waveform output (list mode and trigger delayer), the UDP3000S series and the switching UDP6700\/UDP6900B series add those capabilities.\u003c\/p\u003e\n\u003ch3\u003eWhy is the rated output power 192 W if 32 V × 6 A = 192 W?\u003c\/h3\u003e\n\u003cp\u003e192 W is the rated output power, which equals the maximum simultaneous voltage × current product the supply can deliver continuously on the main channel. The 32 V ceiling and 6 A ceiling are the individual maxima; the supply can deliver any voltage\/current combination inside the 192 W envelope, including 32 V at lower currents or 6 A at lower voltages. The auxiliary 5 V \/ 2 A rail (10 W) is independent of the main channel's 192 W budget; the front-panel USB charging port (also 5 V \/ 2 A, 10 W) is a third independent output and likewise does not draw from the main channel's budget.\u003c\/p\u003e\n\u003ch3\u003eWhat's included in the box?\u003c\/h3\u003e\n\u003cp\u003eInstrument, region-specific power cord, USB communication cable, output cables, English user manual, factory calibration certificate.
