The HAMEG HM 8142 is a high-quality programmable triple-output power supply manufactured in Germany, designed for R&D labs, engineering workstations, and educational institutions. Operating on standard 50-60Hz mains, this unit provides exceptional stability, low ripple, and unique arbitrary waveform capabilities typically found in much higher-priced instruments. Whether you need a reliable source for circuit prototyping or a versatile tool for automated testing, the HM 8142 delivers professional-grade performance.

Key Features & Benefits

Triple Outputs for Maximum Versatility

• 2x Adjustable Outputs: 0-30V / 0-2A (or 0-1A depending on revision)

• 1x Fixed Output: 5V / 2A (perfect for digital logic circuits)

• Allows simultaneous powering of analog circuits and digital components 

"Made in Germany" Quality

• Robust mechanical construction and superior thermal design
