FAQ

Q1: What makes this 250V/3000mA power supply different from standard 600V power supplies?

A: The key difference lies in the Current (mA) capacity. While standard power supplies offer high voltage but low current (usually under 800mA), this unit is a specialized High-Current Powerhouse (up to 3000mA / 3A). Applications like Western Blotting (electrotransfer) and large-scale horizontal gels require huge amounts of current at lower voltages. This power supply is specifically engineered to deliver that massive current stably, making your protein transfers faster and more efficient.

Q2: Is this power supply suitable for Western Blotting tank (wet) and semi-dry transfers?

A: Yes, absolutely. In fact, it is the ideal choice for both.

Tank/Wet Transfer: Often requires high current over a longer period, which can cause standard power supplies to overheat or trip. This unit handles it effortlessly.

Semi-Dry Transfer: Requires very high current (often 1–2A or more) for rapid, high-efficiency transfers. With a 3A maximum output, this device can easily power multiple semi-dry or rapid transfer slots simultaneously.

Q3: Can I run multiple electrophoresis tanks or transfer cells at the same time?

A: Yes. The unit comes with 4 pairs of parallel output terminals, allowing you to connect up to 4 devices at once. Because of its massive 3000mA current ceiling, you don't have to worry about the power supply dropping its output when you plug in multiple high-demand transfer cells. (Note: All connected tanks must run under the same programmed settings and duration).

Q4: How does the "Triple Constant Control" mode protect my high-current experiments?

A: High-current runs generate a lot of heat, and as the buffer warms up, the electrical resistance drops. If you are running in Constant Voltage mode, a drop in resistance will cause the current to spike dramatically, which can melt your gel or ruin your transfer. Our Smart Triple Constant Control allows you to set a constant voltage while capping the maximum current and power. The system dynamically manages the parameters to ensure the buffer never overheats, keeping your proteins safe.

Q5: Can I use this power supply for routine DNA/RNA agarose gel electrophoresis?

A: Yes, you can. Routine DNA/RNA horizontal electrophoresis typically runs between 50V to 150V, which falls perfectly within this unit's 2–250V range. It is highly versatile and can serve as a reliable daily workstation for nucleic acid separation when it is not being used for heavy blotting work. (Note: It is not suitable for high-voltage applications like Isoelectric Focusing (IEF) or sequencing gels that require over 250V).

Q6: Does it support global power grids (110V and 220V)?

A: Yes. The internal power module is adaptive and fully compatible with an input voltage range of AC 110V–240V, 50/60Hz. It operates perfectly in North America, Europe, Asia, and other regions without any modifications. We will ship the unit equipped with the matching power plug (US, EU, UK, or AU) according to your country.

Q7: What happens to my transfer if the laboratory experiences a brief power flicker?

A: Your experiment is fully backed up. The power supply features an Intelligent Power-Out Recovery function. If power is interrupted, the device automatically memorizes the exact parameters and remaining time of your run. Once the power returns, it resumes operation seamlessly from where it was interrupted, preventing the loss of valuable antibodies and protein samples.
