The Tektronix 2380J-500-30 is a programmable DC electronic load instrument engineered for rigorous power source validation and characterization. It delivers 750 W of dissipation across five distinct operating modes—constant current (CC), constant voltage (CV), constant resistance (CR), constant power (CP), and transient—making it suitable for stress testing, accelerated life testing, LED driver validation, automotive electronics assessment, and battery discharge analysis.
Technical Specifications
The instrument operates from 0–500 V with dual input ranges (0–50 V low, 0–500 V high) and accommodates load currents from 0–30 A (high range) or 0–3 A (low range). Voltage and current measurements update at 50 kHz, while load current switching reaches 25 kHz. Readback resolution stands at 1 mV for voltage, 0.1 mA or 0.01 mA for current, and 10 mW for power. Programmable current slew rates span 0.0001 A/µs to 2.5 A/µs, with rise and fall times up to 1 A/µs.
AC input is switchable between 120 VAC and 240 VAC nominal (100/220 V or 115/230 V, 50/60 Hz). Fan cooling maintains operation across 0 °C to 40 °C.
