The Keithley 2268-60-14 is an 850 W programmable DC power supply engineered for research, development, and manufacturing environments requiring precise voltage and current control. It delivers up to 60 V and 14 A, housed in a compact 1U, half-rack width enclosure designed for efficient rack integration with front-to-back ventilation and side-by-side mounting capability.
## Technical Specifications
• **Output Power:** 850 W maximum
• **Output Voltage:** 60 V maximum
• **Output Current:** 14 A maximum
• **Output Modes:** Constant Voltage (CV), Constant Current (CC), Constant Power (CP)
• **Auxiliary Outputs:** Two isolated outputs at 15 V and 5 V for external device control and signaling
• **AC Input:** 85 Vac to 265 Vac, single-phase, 47 Hz
• **Operating Temperature:** Up to 50°C ambient
• **Enclosure:** 1U height, half-rack width; 44 mm (H) × 214 mm (W) × 495 mm (D); 5 kg
## 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
