Overview
The Wiseman DL Series is a precision-engineered 19-inch rack-mount high-voltage DC power supply designed for demanding laboratory, industrial, and research applications requiring stable, programmable, and highly protected high-voltage output. Built on a robust modular architecture, the DL Series operates on the principle of regulated switched-mode high-voltage generation with multi-stage filtering and active feedback control—ensuring minimal output perturbation under dynamic load conditions. Its core design targets applications where voltage integrity, long-term drift performance, and fail-safe protection are non-negotiable: electrophoresis instrumentation, X-ray tube biasing, electrostatic processing (e.g., electrospraying, electrospinning, corona charging), particle accelerator subsystems, and high-energy physics test benches. With output capabilities spanning 1 kV to 130 kV and up to 1.2 kW continuous power, the DL Series supports both fixed and fully adjustable output configurations, meeting stringent requirements for reproducibility in GLP-compliant analytical workflows and ISO/IEC 17025-accredited calibration environments.
Key Features
- Ultra-stable output: Voltage stability better than 100 ppm over 8 hours after thermal stabilization (30-minute warm-up); temperature coefficient ≤25 ppm/°C — suitable for metrology-grade instrumentation integration.
- Low-noise regulation: Ripple voltage limited to 0.1% peak-to-peak across full load range; optimized filtering minimizes electromagnetic interference (EMI) coupling into sensitive detection circuits.
- Comprehensive safety architecture: Integrated hardware-level protections include overvoltage lockout (OVP), overcurrent shutdown (OCP), arc fault detection (AFD), short-circuit current limiting, overtemperature cutoff, and mandatory safety interlock circuitry compliant with IEC 61010-1.
- Dual-mode control: Local operation via front-panel 4-digit LED meters and precision multi-turn potentiometers; remote control via standard RS-232 serial interface or Ethernet (TCP/IP), with optional RS-485 for industrial daisy-chaining.
- Flexible form factor: Available in 1U (44 mm) and 2U (88 mm) rack heights; mechanical footprint conforms strictly to EIA-310-D standards (483 mm width); depth variants accommodate both compact (483 mm) and extended-output (610 mm) configurations.
- Configurable output behavior: Optional firmware-enabled modes include Constant Power Control (CPC), Low-Ripple Enhancement (LR), Floating Ground (FG), and Arc-Tolerant Protection (AT); all user-selectable without hardware modification.
Sample Compatibility & Compliance
The DL Series is specifically engineered for integration with electrophoresis systems—including high-resolution native PAGE, SDS-PAGE, and capillary electrophoresis platforms—where precise, low-drift HV bias directly impacts band resolution and reproducibility. It also serves as a certified bias supply for radiation-generating devices (e.g., X-ray tubes per IEC 60601-2-54), electrostatic precipitators (meeting EPA AP-42 emission control specifications), and semiconductor wafer charging test stations. All units carry CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and support audit-ready documentation packages for FDA 21 CFR Part 11 compliance when used with validated control software. Mechanical and electrical interfaces adhere to IPC-6012 Class 2 standards for printed circuit board assembly integrity.
Software & Data Management
Standard Ethernet and RS-232 interfaces enable seamless integration into LabVIEW™, Python (PySerial, socket), or MATLAB® automation frameworks. The embedded command set supports SCPI-like syntax for voltage/current setpoint programming, status interrogation (e.g., MEAS:VOLT?;, STAT:QUES:COND?), and real-time alarm reporting. Firmware logs all critical events—including arc counts, thermal excursions, and interlock triggers—with timestamped entries stored in non-volatile memory. Optional Wiseman Control Suite (v3.x) provides GUI-based monitoring, trend visualization, CSV export, and configurable email/SNMP alerts—fully compatible with enterprise LIMS and ELN platforms. Audit trails meet ALCOA+ principles, supporting GxP-regulated environments requiring traceability of parameter changes and operational states.
Applications
- Electrophoresis system powering (including high-field pulsed-field gel electrophoresis)
- Bias supply for X-ray tubes, electron multipliers, and photomultiplier tube (PMT) dynode chains
- Electrostatic process engineering: spray coating, fiber spinning, flocking, and air filtration charging
- Capacitor charging for pulsed-power experiments and laser flash lamp drivers
- Ion beam extraction and focusing in compact accelerator test stands
- Dielectric withstand and insulation resistance testing per ASTM D149 and IEC 60243
- Accelerated aging of electronic components under controlled HV stress
FAQ
Is the DL Series compatible with third-party electrophoresis instruments?
Yes — the DL Series features standardized analog (0–10 V) and digital (RS-232/Ethernet) control interfaces, enabling interoperability with major electrophoresis platforms including Bio-Rad, Thermo Fisher, and Helena Laboratories systems.
Can output polarity be reversed?
Negative-polarity configurations are available as factory-configured options; custom polarity selection must be specified at time of order and cannot be changed in-field.
What is the warranty and calibration interval recommendation?
Wiseman provides a 24-month limited warranty; NIST-traceable calibration is recommended annually or after any event involving overvoltage/overcurrent fault recovery.
Does the unit support remote firmware updates?
Yes — secure firmware upgrades are supported via Ethernet using signed binary packages; update logs are retained in system history with SHA-256 checksum verification.
Are custom mechanical enclosures or cooling solutions available?
Custom chassis modifications (e.g., forced-air ducting, liquid-cooled variants, or EMI-shielded housings) are offered under Wiseman’s OEM Engineering Services program with lead times starting at 12 weeks.
