DP800 transient voltage on power up

Posted on: December 16th, 2020 by Doug Lovell

The DP800 series power supply will show a transient voltage on the outputs when the power supply is powered up. Typically the transient voltage will show approximately 400mV p-p over a 200us duration. 

The DP800 power supplies do not have output relays to to  enable output after the power supply has been  turned on and has stabilized. It is recommended that connections be made to a device after the power  supply has been powered  up if  you are working with circuitry that is sensitive to this transient voltage.
