40Fig.5-3: Series connection for positive/negative output voltages3. Programming by external resistor:1. Programming by external voltage:Programming by external resistor is possible . Refer tosection 6-5 for details.The analog programming circuits of this power supplyare referenced to the negative Sense potential.Therefore, the circuits used to control each seriesconnected unit must be separated and floated fromeach other.The communication port is referenced to the IF_COMwhich is isolated from the power supply outputpotential. Therefore power supplies connected inseries can be chained using the Remote-In andRemote-Out connectors. Refer to chapter 7 for details.The Shut-Off and PS_OK circuits are referenced to theisolated interface common, IF_COM (J1-2,3). TheIF_COM terminals of the units can be connected toobtain a single control circuit for the power suppliesconnected in series.4. Programming via the SerialCommunication port (RS232/RS485):4. Programming via the SerialCommunication port (RS232/RS485):5.14.2 Series connection for positive and negative output voltageIn this mode, two units are configured as a positive and negative output. Set the current limit of eachpower supply to the maximum that the load can handle without damage. It is recommended thatdiodes be connected in parallel with each unit output to prevent reverse voltage during start-up or incase one of the units shuts down. Each diode should be rated to at least the power supply ratedoutput voltage and output current. Refer to Fig.5-3 for this operating mode.+S+--S-LS+LSPOWERSUPPLY+S++---S-LS+LSPOWERSUPPLYCOM.Remote programming in series operation for positive and negative output voltage2. Using the SO function and PS_OKsignal :3. Programming by external resistor : Programming by external resistor is possible. Referto section 6.5 for details.The communication port is referenced to the IF_COMwhich is isolated from the power supply outputpotential.
