5 kHz Dynamic Transient Mode
Switches dynamically between preset A/B levels at up to 5 kHz to simulate high-speed current transients and evaluate power dynamic response.
5-Fold Safety Shield
Comprehensive 5-fold hardware protection (OCP / OVP / OPP / OTP / LRV), plus reverse-polarity and overload protection, ensures reliable and safe operation in demanding production and laboratory environments.
Remote Sense (Lead Drop Compensation)
Equipped with remote Sense terminals to compensate for cable voltage drops in real time, eliminating long-wire and low-impedance errors for true DUT voltage readout.
Battery Discharge Test (Opt.)
Dedicated for Li-ion / Lead-Acid / Supercaps with smart V-stop / C-stop/ T-stop cut-off triggers, real-time PC V/I/C curve logging, and high-speed sorting.
OCP / OPP Auto-Test (Opt.)
Automatically simulates over-current/power faults and pinpoints trip thresholds to verify power and battery module protection response and safety.
Multi-Port Interfaces
Built-in USB/RS232/LAN with SCPI support and PC control for fast automated ATE integration and real-time data acquisition.
Parallel Scalability (Up to 10 Units)
Supports precision parallel operation of up to 10 units, scaling total capacity up to 4kW / 400A with active current sharing.
Built-in Ripple Analysis (Opt.)
Standalone precision Vpp / Ippripple measurement without external oscilloscopes or probes, simplifying wiring and doubling test throughput.
