First, the combined voltage should not exceed the output breakdown voltage rating of the supplies. So, for example, dont connect the outputs of three 200 volt supplies in series if their output breakdown voltage rating is 600 volts or less. Second, the output connections for each power supply should have a reverse biased diode wired across them (se

Auto-series operation permits equal or proportional voltage sharing, and allows control of output voltage from one master unit. The voltage of the slaves is determined by the setting of the front panel VOLTAGE control on the master and voltage divider resistor. The master unit must be the most positive supply of the series. The output CURRENT contr

Here are the following benefits: 1. Efficient power utilization limited only by the output voltage accuracy of each supply. 2. No circuits required to control voltage or current sharing between the supplies. 3. No sensitivity to design or construction of conductors connecting supplies in series. 4. Easily designed with any combination of power supp

The maximum load current should not exceed the smallest rated output current, when selecting power supplies with different current ratings. Any number of power supplies can be connected in series. System designers must note that an output voltage > 60Vdc will not meet SELV requirements, and can be dangerous. Under no circumstances the total volt

Some possible combinations could be: 1. 24Vdc@30A power supply in series with a 24Vdc@18A power supply can be used as a 48Vdc@18A power supply. 2. 12Vdc@60A power supply in series with a 12Vdc@37A power supply can be used as a 24Vdc@37A power supply. 3. 18Vdc@40A power supply in series with a 6Vdc@68A power supply can be used as a 24Vdc@40A power s
