Overview
The Kikusui PAN160-7A is a high-reliability, benchtop adjustable DC regulated power supply engineered for mission-critical applications in R&D laboratories, quality assurance testing, and industrial production environments. Designed as the successor to the legacy PAN series, the PAN-A family integrates advanced analog regulation architecture—combining a FET-based pre-regulator with a discrete power transistor-based series pass element—to deliver exceptional output stability while minimizing input harmonic distortion. Unlike switching-mode alternatives, this linear topology ensures ultra-low electromagnetic interference (EMI), making it suitable for sensitive instrumentation calibration, semiconductor device characterization, and precision electrochemical testing where spectral purity and transient fidelity are paramount. The unit operates within a fully isolated floating output configuration, supporting bipolar operation via external grounding schemes, and maintains strict compliance with safety-critical design principles including component derating, thermal margin analysis, and mechanical safeguarding of all high-voltage terminals.
Key Features
- Ultra-Low Temperature Drift: Achieves 100 ppm/°C voltage drift and 300 ppm/°C current drift through precision component selection, optimized thermal layout, and forced-air cooling calibrated for continuous 100% load operation.
- High-Bandwidth Transient Response: Employs a wide-gain-bandwidth error amplifier with phase-stable loop compensation, enabling sub-50 µs recovery time following a 20% load step—critical for dynamic load simulation and pulsed-current testing.
- Low-Ripple Linear Regulation: Delivers RMS ripple and noise below 1 mV across full load range; peak-to-peak noise remains <5 mV without external filtering, ensuring compatibility with low-noise analog circuits and photodetector biasing.
- Comprehensive Safety Architecture: Integrates hardware-enforced overvoltage protection (OVP), overtemperature shutdown (OTP), foldback current limiting, and front-panel terminal covers conforming to IEC 61010-1 finger-protection requirements (IP2X).
- Enhanced Ground Isolation: Supports ±500 Vdc isolation between output terminals and chassis ground—doubling the previous PAN-series rating—enabling safe operation in high-common-mode-voltage test setups such as battery stack emulation or floating sensor excitation.
Sample Compatibility & Compliance
The PAN160-7A is certified to IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and EN 61326-1 (EMC for Test and Measurement Equipment). Its reinforced terminal insulation, recessed binding posts, and AC inlet redesign (replacing older piano-key connectors on 350W+ models) meet updated regional requirements for operator protection under fault conditions. The unit supports GLP/GMP-aligned validation protocols through traceable calibration points and stable long-term output repeatability (<0.02% load regulation). It is routinely deployed in ISO/IEC 17025-accredited labs for calibration of multimeters, data acquisition systems, and programmable loads.
Software & Data Management
While the PAN160-7A operates as a standalone analog instrument, it includes standard analog remote sense and 0–5 V/0–10 V analog programming interfaces compatible with PLC-based test sequencers and SCADA systems. Optional GPIB (IEEE-488.2) and RS-232 interfaces enable integration into automated test environments compliant with IEEE 1226 ATE standards. All firmware and control logic reside in non-volatile memory with checksum verification; no embedded OS or network stack is present—minimizing cybersecurity attack surface per IEC 62443-3-3 guidance for laboratory infrastructure.
Applications
- DC biasing of RF power amplifiers and microwave mixers requiring clean, stable supply rails
- Accelerated life testing of electrolytic capacitors and solid-state relays under constant-voltage stress
- Calibration reference source for digital multimeters (DMMs) and source-measure units (SMUs) per ANSI/NCSL Z540 and ISO/IEC 17025
- Power supply rejection ratio (PSRR) characterization of LDO regulators and analog front-end ICs
- Floating ground testing of automotive ECUs and aerospace avionics modules operating at elevated common-mode potentials
