Systron Donner M107 precision DC voltage source. The M107 has programmable or manual control of output voltage, polarity, and range. It has 6 digits of resolution and ±0.002% accuracy on all ranges. Front and rear panel outputs make it easy to use on a bench or in a rack.

 
Features:

• Voltage output: from 1 μV to 1 kV, 50 mA max., with ±0.0001% regulation (line or load).
• Isolation DC output: up to ±500 Vdc.
• Polarity selection: +, -, and standby (short circuit across output terminals)
• Output Terminals: five terminals on the front panel and five pin connector on the rear panel (2) DC output, (2) sense; (1) chassis ground
• IEEE-488 Interface
• Manual control of output voltages, polarity, range and current via the front panel
• Six digits of resolution
• 120/240VAC
