VWR E0302-VWR 300V DC Laboratory Power Supply Unit

The VWR E0302-VWR 300V is a versatile DC laboratory power supply unit offering a maximum output power of 90 watts with an adjustable voltage range from 2 to 300 V and current range of 4 to 500 mA. It supports both constant voltage (CV) and constant current (CC) operating modes with precise incremental settings of 1 V and 1 mA respectively, making it ideal for sensitive applications in biotechnology, molecular diagnostics, and bioprocessing.

Key technical features include:

• Duration time limits settable from approximately 1 minute up to 99 hours 59 minutes for extended experimental protocols.
• Multiple terminal pairs: 4 positive and 4 negative voltage outputs enabling flexible configurations for complex circuitry or multi-channel experiments.
• Integrated safety mechanisms such as No Load Detection, Load Change Detection, Overload Detection, and Ground Leak Detection to ensure reliable operation and protect sensitive biological instrumentation.
• Convenient pause function and automatic crossover that enhance experimental control without interrupting workflow.
• Rugged, flame-retardant ABS housing resistant to common laboratory environments.
• Compact footprint with dimensions 200 x 290 x 70 mm and lightweight design (1.2 kg) suitable for benchtop placement.

This power supply unit is widely adopted in biotechnology laboratories for applications requiring stable electrical inputs, including gene editing device calibration, electroporation setups, and live-cell imaging instrumentation power regulation. Its precise voltage and current control support reproducible results critical for biomanufacturing and molecular cloning workflows.
