DP700 series Power Supply Maximum Trigger Input Voltage

Posted on: December 16th, 2020 by Doug Lovell

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.
