The Keysight EL34243A is a dual-input, 600 W programmable DC electronic load engineered for power source and component validation. It delivers four operating modes—Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR), and Constant Power (CP)—plus dedicated battery test functionality with programmable cut-off conditions. Each input accepts 0–150 V, 0–60 A, and 300 W; combined in parallel mode, the unit reaches 600 W and 120 A total.

– Key Features
Measurement Integration
Built-in voltmeter and ammeter eliminate external meters and shunts. The data logger captures voltage, current, and power dynamics with adjustable sample rates from 20 microseconds to 60 seconds, storing data as CSV to internal memory or USB. Scope View digitizes and displays waveforms without external probes.
Remote Sense Technology
2-wire and 4-wire remote sense compensation corrects for voltage drops across interconnect, improving load regulation accuracy.
Protection Suite
Fixed and programmable over-current protection (OCP), over-voltage protection (OVP), and over-power protection (OPP).
Battery Test Mode
Precise voltage and capacity control with customizable termination by voltage, capacity, or timer.
– Interfaces & Connectivity
USB-TMC (4 ports), USB-CDC virtual COM, LAN (LXI Core), and optional GPIB support integrated remote operation and data transfer.
– Typical Applications
Consumer power supplies, batteries, solar panels, and LED drivers.
