Introduction

The document describes the DNA series of compact high voltage modules designed for applications requiring high stability, ultra-low ripple, and compact size. These modules are suitable for use in fields such as DNA sequencing, mass spectrometry, electron microscopy, electrophoresis, semiconductor testing, medical imaging (SPECT, PET scanners), and other scientific and industrial applications.

Applications

• Life Science and Medical Industry (e.g., DNA sequencing, blood analysis, PET/SPECT scanners)
• Scientific Experiments (e.g., electron beam ion beam, electron multiplying detectors)
• Industrial Applications (e.g., semiconductor testing, capacitor charging, electrostatic discharge tests)

Specifications

The DNA series offers models with maximum output voltages of 20kV and 30kV, with output power ratings around 15W to 30W. Output polarity options include positive and negative. Key electrical parameters include:

• Ripple: <= 0.01% peak-to-peak
• Stability: less than 0.01% per hour and less than 0.02% over 8 hours after 30 minutes warm-up
• Temperature coefficient: <= 25 ppm/°C
• Input regulation and load regulation: approximately ±0.01%

Input voltage variations of ±10% result in minimal output changes, demonstrating high regulation performance.

Features

• High stability and low ripple output
• Compact size with dimensions approximately 43mm x 100mm x 205mm
• Lightweight: 1 kg for 20kV models and 1.45 kg for 30kV models
• Convection cooling suitable for operating temperatures from -20°C to +50°C and storage from -40°C to +85°C
• Humidity tolerance: 20% to 85% non-condensing
• Built-in protections: arcing, short circuit, and overload protection
• Voltage and current programming via potentiometer or external reference voltage
• Optional digital control interfaces: RS-232 and RS-485
• OEM customization available

Options and Accessories

High voltage cable options include non-shielded and shielded cables with customizable lengths (e.g., 1 meter standard length with options for longer cables).

Control and Connectivity

The modules support both analog and digital control modes:

• Analog control inputs allow 0-5 V DC signals to program output voltage and current from 0 to 100% of maximum.
• Digital control via RS-232 or RS-485 interfaces enables remote programming and monitoring.

Mechanical Dimensions and Connectors

The mechanical layout includes an 8-pin input connector with clearly defined pins for input voltage, ground, programming inputs, and display outputs for voltage and current. The compact form factor facilitates integration into various systems.

Environmental and Operational Limits

• Operating temperature range: -20°C to +50°C
• Storage temperature range: -40°C to +85°C
• Humidity: 20% to 85% relative humidity, non-condensing
• Cooling method: convection cooling

Summary

The DNA series high voltage modules provide reliable, stable, and low-noise high voltage power suitable for precision scientific instruments and industrial equipment. Their compact size, comprehensive protection features, and flexible control options make them ideal for integration into advanced analytical and testing systems.
