EV3330 Consort Maxi Power Supply: High-Voltage Precision for IEF
The EV3330 Consort Maxi Power Supply is a high-specification unit designed to meet the rigorous requirements of high-voltage electrophoretic applications. With a potent output of 3000V and 200mA, this power supply is specifically engineered for techniques demanding high potential fields, such as DNA sequencing and Isoelectric Focusing (IEF). Unlike standard units that may fluctuate under high-resistance loads, the EV3330 ensures stability and precision, making it an essential partner for genomic and proteomic research laboratories seeking reproducible high-resolution separations.
A standout feature of the EV3330 is its dedicated “IEF Mode,” which is optimised for low-current applications. During isoelectric focusing, current often drops significantly as proteins migrate to their pI; this unit is capable of measuring and regulating currents as low as 10 microAmps, ensuring the electrical field remains constant throughout the critical final stages of the run. The system also features four parallel output pairs, allowing for the simultaneous operation of multiple tanks to maximise throughput, alongside advanced safety protocols including ground leakage and no-load detection.
Key Benefits:
- High Voltage Output: 3000V capacity. Delivers the high voltage necessary for efficient DNA sequencing and high-resistance IEF strips or gels.
- Specialised IEF Mode: Low-current stability. Engineered to maintain precise voltage control even at very low currents (down to 10µA), critical for focusing bands.
- Quad-Output Design: Maximise efficiency. Equipped with four parallel output pairs, enabling the user to run up to four electrophoresis units simultaneously.
- Advanced Programming: Flexible control. Supports 9 different methods with up to 9 steps each, including voltage ramping and timer-controlled operation for complex protocols.
- Intelligent Safety: User protection. Features comprehensive safety systems including ground leakage detection, overload protection, and automatic crossover to prevent equipment damage.
Technical Insights
The EV3330 incorporates a user-friendly interface with a clear graphical display that provides real-time feedback on voltage, current, and power. The unit’s firmware allows for “Voltage Ramp” protocols, applying a linear voltage gradient that is essential for specific separation techniques. Additionally, the integrated USB interface facilitates firmware updates and data logging, ensuring that every run is traceable and that the unit remains up-to-date with the latest operational features.
