Decoupling diode serial for DC sources

Decoupling diodes are used to protect against unwanted reverse voltage into the laboratory power supply and to protect against overvoltages that do not reach 150% of the maximum output voltage. Semiconductor diodes are connected in series to the output. This feature avoids energy being discharged into the output circuit when batteries are connected to the DC source.

Normally, relays are used for this protection, but they have to be controlled, which is not required with a decoupling diode. Typical applications for this option in a laboratory power supply are charging batteries, charging capacitors or operating and testing electric motors.

The decoupling diode series (DDS) option has been designed for the DC sources of the LAB/SMP and LAB/HP series with output powers from 750 W to 1.4 MW and output voltages up to 2000 VDC.
