• It is possible to customize time synchronization to a time server.
• Remote sense functionality compensation voltage up to 5V.

Operational

• 5″ touch screen with 3 definable background colors, 3 spin knobs with push-select and two push
• buttons give a clear and intuitive control.
• Patented multi-function HOME/RETURN key.
• Patented output ON/OFF button gives an extra layer of safety, allowing powered output only when
• Two kinds of output mode which can be changed following adjustment or after confirmation.
• both internal switches are triggered.
• Programmable over-voltage and over-current protection.
• Programmable output ramp-up and ramp-down protect the device under test.
• Up to 8000 sets of V/A/W data at 1ms intervals can be recorded and stored.
• Three sets of settings can be stored and recalled from the front panel.
• DSP-WR Series remote control application software gives control and sequence data setting to the DC power supply.
• Data logging is timestamped.

Safety
