Electrophoresis Power Supply DYY-BS300B

Short Description:

DYY-BS300B power supply supports an output of 300V, 400mA, 120W, which is our common product used by our customers. It is designed to apply in DNA, RNA, Protein electrophoresis. We adopt the microcomputer processor as the control center of DYY-6C. It has the following advantages: small,, light, high output-power and stable functions. Its LCD can show you the voltage, current, power and timing time at the same time. It can work in the constant state of voltage, or in the constant state of electric current, and converted automatically according to the pre-assigned parameters for different needs.

Feature

• Output Modes: Constant Voltage (CV), Constant Current (CC), Constant Power (CP).

• One-Touch Setup: One-click protein mode setup—automatically switches from stacking gel to resolving gel phase without manual reset, simplifying operation.

• Smart Triple Constant Control: Set any constant value (voltage, current, or power); the other two are automatically limited to prevent overload, ensuring dynamic triple-constant operation.

• Micro-Current Maintenance: After electrophoresis ends, the system can automatically switch to micro-current mode to prevent sample diffusion or overrun during unattended operation.

• Large Display: 4.3-inch touchscreen with real-time touch control, showing voltage, current, power, and time simultaneously; both preset and actual values are clearly visible.

• User-Friendly Interface: Intuitive, smartphone-like interface for simple and efficient operation.

• Power-Out Recovery: Automatically memorizes the running state during a power failure, and resumes the process upon power restoration.

• Auto Memory & Shutdown: Features automatic memory and auto power-off functions

• Wide Input Voltage Range: AC 110V–240V, 50/60Hz input, highly adaptable to global power standards.

• Method Storage: Programmable storage of up to 20 methods, each with up to 10 steps

• Safety Features: Over voltage, arc, no-load, and sudden load change detection; overload/short-circuit monitoring; leakage protection; open-circuit alarms.

FAQ

Q1: How do I choose between Constant Voltage (V), Constant Current (mA), and Constant Power (W)?

A: It depends on your specific electrophoresis application:

• Constant Voltage (Recommended for Nucleic Acid Gels): As the run progresses, resistance drops, and current increases. This keeps the migration rate of DNA/RNA relatively constant in agarose gels.

• Constant Current (Recommended for Protein Gels): Ideal for SDS-PAGE and Western Blotting. It prevents overheating as the buffer resistance changes, ensuring sharp protein bands.

• Constant Power (Recommended for Sequencing Gels): Keeps the heat generation completely uniform across large sequencing gels to prevent smiling bands.

Q2: Can I run multiple electrophoresis tanks simultaneously with one power supply?

A: Yes, our power supplies come with multiple output terminals (typically 2 or 4 pairs of slots arranged in parallel). This allows you to run up to 2 or 4 gel tanks at the exact same time, provided they all require the same voltage or current settings.

Q3: What safety features are built into your power supplies?

A: Safety is our top priority. Our systems feature an intelligent micro-computer control system equipped with:

No-Load Detection: Automatically pauses output if a tank is disconnected or buffer levels are too low.

Short-Circuit & Overload Protection: Instantly cuts off power if a sudden surge or short circuit is detected.

Automatic Recovery: Resumes the run seamlessly after a brief power interruption (depending on the model).

Insulated Terminals: Recessed jacks prevent accidental shock during cable connection.

Q4: What is the difference between a High-Current, High-Voltage, and Universal Power Supply?

A: High-Voltage Models (up to 3000V/5000V): Designed for DNA sequencing, isoelectric focusing (IEF), and RNA analysis.

High-Current Models (up to 2A/3A): Designed for rapid Western Blot transferring (blotting) and high-throughput protein electrophoresis.

Universal/Standard Models (typically 300V or 600V): The most versatile choice for everyday lab work, covering standard submarine agarose gels and mini SDS-PAGE gels.

Q5: Is there a pause function during the run, or do I have to restart the program?

A: Yes, our power supplies feature a "Pause/Resume" button. You can pause the run at any time to check the dye front, adjust settings, or inspect the gel, and then resume exactly where you left off without resetting the timer or parameters.

Q6: Can this power supply be used internationally (110V vs. 220V)?

A: We offer models with adaptive wide-range power input (100V-240V, 50/60Hz) as well as specific 110V and 220V configurations. Please select your region's voltage option when placing your order, and we will equip your unit with the correct power plug (US, EU, UK, or AU) standard for your country.
