Remote Monitoring Of Output Voltage And Current - Delta D750 User Manual

User Manual
D750
DC Power Supply
NOTES:
1. SW1 positions 4, 5, 6 and 9 are not required for remote programming. Their setting can
be determined according to the application requirements.
2. The control circuits allow the user to set the output voltage and current limit up to 5%
over the model-rated maximum value. The power supply will operate within the extended
range, however it is not recommended to operate the power supply over its voltage and
current rating and performance is not guaranteed.
3. To maintain the temperature stability specification of the power supply, the resistors used
for programming should be stable and low noise resistors, with temperature coefficient of
less than 50ppm.
4. When resistive programming is used, front panel and computer control (via serial
communication port) of output voltage and current are disabled.
