Key Features

Programmable Control: Auto-sequence programming mode executes stored command lists internally, reducing test duration by minimizing bus communication overhead

Multi-Unit Scaling: Supports master/slave configuration for up to 30 Series 2268 supplies through a single controller; series operation available for up to two units with external diodes

Analog Control: Isolated and non-isolated analog inputs accept voltage or resistance signals for remote setpoint control; isolated inputs mitigate noise in electrically hostile environments

Protection Architecture: Over-voltage, under-voltage, over-current, and over-temperature protection with programmable thresholds; hardware output interlock for external shutdown; foldback mode with adjustable delay prevents load-induced CV/CC switching shutdowns

Group Control: Loop protection enables coordinated shutdown of up to four supplies in multi-unit configurations

Interfaces & Integration

Digital Interfaces: LAN, USB, GPIB, RS-232, RS-485 standard

Analog Interface: Isolated and non-isolated control input support
