Product Description

Three-channel high-precision power supply with independently controllable outputs, total power 220 W
Clear graphical interface with waveform display function
Internal 5 sets of system parameters save/recall, supports data storage space expansion
100 V/120 V/220 V/230 V compatible design to meet different grid requirements

LBTEK offers four types of high-precision programmable DC power supplies with different accuracy settings. The product features three independently controllable high-precision power outputs: 32 V/3.2 A×2, switchable among 2.5 V/3.3 V/5 V/3.2 A×1, with a total power of 220 W. Built-in protection functions such as overvoltage/overcurrent/overtemperature/short-circuit/overload, along with an intelligent temperature-controlled fan, effectively reduce noise, making it suitable for various types of production and research applications. The 100 V/120 V/220 V/230 V compatible design enables it to meet the requirements of different power grids.
