Keithley 2380J-120-60^

The Keithley 2380J-120-60 is a programmable DC electronic load that simulates real-world power source conditions across multiple operating modes. Rated for 250 W maximum power, 120 V maximum voltage, and 60 A maximum current, this single-channel instrument delivers precise load emulation for power source validation, component stress testing, and production verification.

## Technical Specifications

The 2380J-120-60 operates from 0 V to 120 V with a maximum current of 60 A. Input power requires 120 to 240 VAC. Voltage readback resolution is 0.1 mV with 0.025% accuracy, while current readback achieves 0.01 mA resolution and 0.05% accuracy. Power readback resolution is 10 mW with 0.1% FS ± 0.1% accuracy across the 200 W to 250 W range. The instrument measures voltage and current at speeds up to 50 kHz.

## Key Features

• **Operating Modes:** Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR), Constant Power (CP), transient modes, LED simulated load testing, and battery test mode
• **Dynamic Performance:** Mode switching speeds reaching 25 kHz with adjustable current rise and fall times from 0.0001 A/µs to 2.5 A/µs
• **Protection:** Over-temperature, over-voltage, over-current, and over-power protection with reverse voltage protection and power-on self-test
• **Current Monitoring:** Direct oscilloscope connection via current monitor interface; external control via 0 to 10 V analog input
• **List Mode:** Programmable sequence execution for complex load profiles

## Interfaces & Control

GPIB (IEEE-488.2), USB (USB-TMC compliant), and RS-232 (DB-9) connections enable local and remote instrument control. BN connectors provide input termination.

## Typical Applications

Environmental stress testing, accelerated life testing of AC/DC power sources and DC/DC modules, LED lighting driver validation, high-power component evaluation, automotive electronics assessment, battery research, and production-line acceptance testing.
