Posted on: December 16th, 2020 by James
16/12/2020
The DP700 series power supply provides a timer function. When the timing output is enabled, the instrument will configure the output voltages and currents based on the preset timer parameters. The edited timer parameters are allowed to be saved to the internal non-volatile memory (NVM), and can be recalled if necessary. ...

DP700 series Power Supply Maximum Trigger Input Voltage

Posted on: December 16th, 2020 by James
16/12/2020
Pin 8 of the RS232 interface on the rear panel is used to receive the external trigger input signal. When it receives a high level signal (≥ 2.1 V, 10 mA), the channel output will be turned on. If 8 volts or greater is applied damage to the power supply I/O circuit can result....
