Advanced Features
Tracking Operation
The ±25V outputs provide symmetrical tracking with ±(0.2% + 20mV) accuracy, essential for powering operational amplifiers and balanced circuits requiring precise dual-rail supplies.
Versatile Configuration
Series Operation: Connect ±25V outputs in series for 0-50V/1A operation
Isolated 6V Channel: Completely isolated from ±25V commons for interference-free operation
Memory and Automation
Store up to 10 complete operating states in non-volatile memory for instant recall of frequently-used configurations. All outputs can be programmed and controlled simultaneously.
Interface and Control
- Front Panel: Vacuum-fluorescent display, rotary encoder, dedicated function keys
- Remote Control: USB, RS-232, optional GPIB with SCPI command compatibility
- Protection: Over-voltage, over-current, over-temperature with automatic shutdown
Wiring Quick-Start
Safety Note: Maximum voltage between any output and chassis ground: ±240VDC
