The HAMEG HM 8142 (H088-2 / Serial: 142951) is a high-precision, programmable dual-channel laboratory power supply designed for R&D, education, service labs, and production testing. Built to operate on standard mains (50-60Hz), this German-engineered unit delivers reliable, low-noise power with advanced tracking and interface capabilities.

With two independent, floating outputs (0-32V / 0-2A per channel), the HM 8142 allows series or parallel operation for up to 64V or 4A. Its intuitive interface, combined with optional remote control (RS-232/IEEE-488), makes it ideal for automated test systems and bench use.
