Bio-Rad POWERPAC 200 Programmable Electrophoresis Power Supply 165-5052

The Bio-Rad POWERPAC 200 (model 165-5052) is a programmable electrophoresis power supply extensively used in molecular biology and biotechnology laboratories for gene editing, molecular diagnostics, and bioprocessing applications. It delivers a variable voltage range of 10 to 300 V in 1 V increments and adjustable current from 4 to 400 mA in 1 mA steps, supporting electrophoresis and other bioelectrical workflows with a maximum power output of 75 W. Featuring an automatic crossover function, the instrument seamlessly switches between constant voltage and constant current modes suitable for a variety of experimental protocols.

Key technical features include a fully adjustable timer from 1 minute up to 99 hours 59 minutes, a clear 3-digit LED display for precise monitoring, and four pairs of recessed banana jack output terminals allowing parallel connections. Safety mechanisms incorporate no-load detection, rapid load change recognition, overload and short-circuit protection, and overvoltage prevention to ensure secure operation.

Designed in compliance with EN-61010 and CE safety standards and suitable for typical lab environments at 0–40 °C, this benchtop power supply is optimal for critical electrophoresis workflows in biomedical engineering and synthetic biology research. Its compact dimensions (21 x 24.5 x 6.5 cm) aid integration into laboratory benches with limited space.

This used unit is sold as-is; performance may not fully match a new device but remains a reliable choice for biomanufacturing pipelines, cell imaging research, and essential molecular cloning workflows. Its robust and programmable electrical output makes it widely adopted by research professionals working in clinical diagnostics and biotechnology fields requiring precise electrical control.
