Details
The Techmize TH6433 is a premium 3-channel programmable DC power supply with a built-in 2-channel electronic load, suitable for all R&D, production-line and lab-bench work where source and sink behaviour need to be tested on the same instrument. CH1 and CH2 each deliver 0-32V at up to 3A and can be linked in series for 0-64V/3A or in parallel for 0-32V/6A, while CH3 provides a USB-style fixed-voltage rail at 1.8V, 2.5V, 3.3V or 5V up to 3A, covering the most common digital logic levels without an external supply. Furthermore, this power supply has a 2-channel electronic load that pulls up to 50W per channel in CC, CV, CR or CP mode. That is a meaningful step up from the GW Instek GPP-3323, which shares its 50W load budget across both source channels.
A linear regulator stage keeps ripple at ≤1mVrms and noise low, and front-panel screw connectors on every channel make wiring fast and secure. CH1 and CH2 each support 100 programmable sequence steps with sine, triangle, step, exponential, logarithmic and user-defined profiles, and real-time voltage/current/power sampling can be recorded straight to a USB stick. The power supply comes with many interfaces, including LAN, RS232, GPIB, USB-CDC and USB-TMC, so this supply integrates easily into automated test benches.
Techmize products are manufactured by Tonghui, the company behind well-known high-quality products in the test & measurement industry. With Techmize, Tonghui has introduced its own-branded European product line with local service and support, offering the same level of quality at a fair price.
