LY DYY-6C Touchscreen Electrophoresis Power Supply (Model 112-0630)

Overview

The LY DYY-6C Touchscreen Electrophoresis Power Supply (Model 112-0630) is a microprocessor-controlled DC power source engineered for precision and reliability in routine nucleic acid and protein electrophoresis applications. Designed to drive horizontal and vertical gel electrophoresis systems—including agarose, polyacrylamide, and SDS-PAGE setups—it delivers stable, programmable voltage and current outputs essential for reproducible band resolution and migration kinetics. Its core architecture employs high-efficiency switching power supply technology, minimizing thermal drift and ensuring consistent output across extended run times—critical for multi-gel or overnight electrophoresis protocols. The device complies with IEC 61010-1 safety standards for laboratory electrical equipment and meets electromagnetic compatibility (EMC) requirements per EN 61326-1, supporting integration into GLP-compliant laboratories where traceable, auditable instrument performance is required.

Key Features

• Intuitive 4.3-inch capacitive touchscreen interface enabling simultaneous real-time display of set voltage, set current, elapsed time, and remaining time—with on-the-fly parameter adjustment during active runs.
• Three operational modes: constant voltage, constant current, and constant power (freely configurable), allowing method-specific optimization for diverse gel matrices and sample types.
• Four independent parallel output channels, each fully isolated and individually controllable—enabling concurrent operation of multiple electrophoresis tanks without cross-channel interference.
• High-resolution digital control: 1 V step size across 6–600 V range; 1 mA step size across 4–400 mA range—supporting fine-tuned method development and validation.
• Non-volatile memory stores up to 10 user-defined protocols with timestamped execution history, facilitating SOP adherence and audit readiness.
• Comprehensive protection suite including automatic shutdown on over-voltage, over-current, over-load, sudden load change, and open-circuit (no-load) conditions—ensuring equipment longevity and experimental integrity.
• Low-noise, fanless thermal design with aluminum alloy housing for passive heat dissipation—suitable for quiet laboratory environments and vibration-sensitive imaging workflows.

Sample Compatibility & Compliance

The DYY-6C supports standard electrophoresis formats used in molecular biology, plant genetics (e.g., seed purity testing per ISTA guidelines), clinical diagnostics, and academic research. It is compatible with common gel systems including mini-vertical PAGE units (e.g., Bio-Rad Mini-PROTEAN), horizontal submarine gels (e.g., Thermo Fisher Owl E2), and custom-built rigs. While gel dimensions and sample capacity depend on the connected electrophoresis chamber—not the power supply—the unit’s 240 W maximum output ensures sufficient headroom for high-throughput or high-resistance gel configurations. All firmware and hardware meet CE marking requirements and conform to ISO/IEC 17025-relevant instrumentation control principles. For regulated environments, the device supports manual logbook documentation and can be integrated into lab-wide electronic record systems via external timing triggers or serial command logging (RS-232 optional).

Software & Data Management

The DYY-6C operates as a standalone instrument with embedded firmware—no proprietary PC software required. However, its real-time parameter logging and protocol recall functionality support full traceability: each executed run records timestamp, setpoints, actual output values, and fault events in internal memory. Users may export session logs via USB flash drive (FAT32 formatted) in CSV format for downstream analysis in Excel or LIMS platforms. Audit trail entries include operator ID fields (manually entered), enabling alignment with FDA 21 CFR Part 11 expectations when paired with institutional procedural controls. Firmware updates are delivered via downloadable HEX files and applied using LY’s certified update utility—maintaining version control and change documentation.

Applications

• Routine DNA fragment separation in agarose gels for genotyping, PCR product verification, and plasmid analysis.
• SDS-PAGE and native PAGE of proteins in quality control labs performing purity assessment or molecular weight determination.
• Seed variety identification and cultivar certification workflows requiring standardized electrophoretic mobility profiling (e.g., esterase or peroxidase zymograms).
• Teaching laboratories where intuitive interface design reduces training overhead and minimizes operational errors.
• Field-deployable or mobile lab setups due to compact footprint (235 × 295 × 95 mm) and low mass (2.5 kg), compatible with standard 100–240 V AC input.

FAQ

Does the DYY-6C support timed ramping or gradient voltage protocols?
No—this model implements fixed-setpoint operation only. Voltage and current remain constant throughout the run unless manually adjusted via touchscreen during operation.
Can the four outputs be configured with different voltages simultaneously?
Yes—each of the four isolated outputs can be independently programmed with distinct voltage, current, and timer settings, enabling heterogeneous multi-tank experiments.
Is remote control via computer or network possible?
Not natively. RS-232 communication is available as an optional accessory module; Ethernet or Wi-Fi connectivity is not supported.
What maintenance is required for long-term reliability?
No scheduled maintenance is specified. Periodic inspection of ventilation grilles and cleaning with dry, lint-free cloth is recommended. Internal calibration is factory-performed and non-user-serviceable.
How does the DYY-6C handle sudden load changes—such as buffer depletion or electrode shorting?
Its adaptive load monitoring circuitry detects abrupt resistance shifts within milliseconds and initiates protective shutdown before output instability affects gel integrity or safety.
