Built with an emphasis on continuous duty cycles and thermal resilience, the instrument ensures operational stability during long-term endurance trials. Extensive multi-tier hardware and software safeties protect both the unit and the device under test against transient overstress, delivering reliable, repeatable measurement outcomes in rigorous industrial and experimental test environments.

Key Features

• Comprehensive Multi-Mode Loading Architecture: Features six core measurement modes—Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR), Constant Power (CP), along with combined CC+CV and CR+CV modes—enabling precise static load profiling across non-linear power supplies and energy storage systems.
• High-Precision Resolution and Readback Accuracy: High-performance processing silicon provides ultra-fine resolution down to 1mV and 1mA with voltage readback accuracy of ±(0.05%+0.1%FS), capturing subtle load variations during delicate low-current and transient evaluations.
• Dedicated Battery Capacity and Discharge Profiling: Integrates automated CC and CR battery discharge testing modes capable of logging cumulative capacities up to 9999Ah, providing essential data for cell degradation, cut-off performance, and state-of-charge determination.
• High-Speed Dynamic and Scan Capabilities: Supports programmable dynamic loading in CC and CV modes with switching intervals from 1ms to 60s at 1ms resolution, alongside automated scan testing to verify power source transient stability and recovery limits.
• Specialized LED Driver Emulation: Simulates real-world LED operational characteristics and non-linear loading conditions to rigorously validate solid-state lighting driver circuits under authentic operational stress.
• Multi-Step List Programming and Short-Circuit Emulation: Offers configurable list modes to cycle through complex multi-phase load sequences and direct short-circuit testing (CC, CV, CR) to evaluate output protection thresholds of upstream power supplies.
• Multi-Stage Hardware and Software Protection: Protects critical circuits via independently programmable overvoltage (OVP), overcurrent (OCP), overpower (OPP), reverse polarity prevention, and dual-stage overtemperature protection (OTP) set at 85°C.
• Intuitive Visual Interface and Security Key Lock: Features a 2.8-inch TFT high-definition display (400×240 resolution) supporting dual-language navigation, instantaneous multi-parameter monitoring, and front-panel key-lock security to eliminate accidental parameter alterations during live cycles.
• Automated Communication and Non-Volatile Data Retention: Equipped with a standard USB Device interface for remote automation, SCADA integration, and continuous data logging, backed by non-volatile memory that preserves test parameters across sudden power interruptions.
• Intelligent Acoustic and Thermal Regulation: Incorporates a smart variable-speed fan controller that dynamically balances internal cooling airflow with ambient noise reduction, maximizing heatsink efficiency under continuous full-load runs.
