Details
The Techmize TH6431 is a premium single-channel programmable DC power supply with a built-in 100W electronic load, suitable for all R&D, production-line and lab-bench work where one high-current rail needs to be both sourced and sunk on the same instrument. CH1 delivers 0-32V at up to 6A, the highest per-channel current in the TH6430 series, while the integrated electronic load pulls up to 100W in CC, CV, CR or CP mode. That is a meaningful step up from the GW Instek GPP-1326, the closest single-channel competitor in this price range.
A linear regulator stage keeps ripple at ≤1mVrms and noise low, and front-panel screw connectors make wiring fast and secure. CH1 supports 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.
