Hoefer® Power Supplies

Small footprint, large handle, and simple operation make Hoefer® Power Supplies easy to set up and use in your lab. With a large, easy-to-read LED, simply set the constant parameter, set the timer (if desired), and push start.

• Constant voltage or constant current mode with automatic crossover
• Four sets of 4 mm output jacks
• Continuous runs or a 999-minute timer
• Automatic recovery after power failure
• Open circuit detection
• Short circuit protection

Modes of operation

Constant Voltage Mode: the power supply will attempt to maintain the user selected voltage by automatically adjusting the current flow.

Constant Current Mode: the power supply will attempt to maintain the user selected current flow by automatically adjusting the voltage supplied.

Automatic Crossover: when the constant parameter (voltage or current) cannot be maintained due to power supply operating limits, the power supply automatically switches to maintaining the other parameter.

• PS300B 300 Volt Power Supply is designed for most electrophoresis techniques.
• PS200HC 200 Volt High Current Power Supply is ideal for large electrophoretic blotting applications and for low voltage electrophoresis runs.
• PS600 600 Volt Power Supply is designed for electrophoresis and blotting techniques, including large format and high throughput applications.
