Key Features
Overvoltage, overcurrent, and overtemperature protection with automatic output shutdown
Low AC input protection (AC-FAIL) turns output off
Programmable voltage and current rise/fall times to prevent inrush damage to low-impedance loads
Constant current priority mode minimizes overshoot when powering LEDs
Programmable output resistance simulates battery characteristics
Internal test sequence mode generates custom voltage waveforms
Analog control input (26-pin rear connector) for voltage/current regulation and status monitoring
Front-panel USB Type-A host and rear-panel USB Type-B control
Remote sensing terminals reduce lead-loss effects in long-cable installations
Typical Applications
LED driver and power supply testing
Battery simulation and emulation
Device characterization and stress testing
Automated production line verification
Research and prototype validation
Compatibility & Integration USB and LAN interfaces enable direct instrument control and data logging. Optional GPIB adapter (2260B-GPIB-USB) extends legacy test system compatibility. Analog input allows integration into existing analog control architectures without external interfaces.
