capture window. If the supplies are not initially adjusted inside the capture window the supplies will not current share satisfactorily.
- Connect load cables to the outputs of each supply.
- Connect the remote sense line s to the load in twisted style. (A common remote sense point must be used for all the supplies
- Connect all the “LS” signal (Pin 10) on the J3 connector between the supplies.
- Adjust remote sense voltage of each supply to within 1% of rated output voltage or re adjust to required set point. (Adjustment
to be done with all other parallel supplies off).
- Current sharing between the supplies can be verified by monitoring the output current of each supply with a hall effect DC
current probe. The supplies should share to within 10% of the total load current.
- The current share circuit has a capture window voltage of +/ - 1% of the rated output voltage. If the output remote sense
voltage of one of the supplies is adjusted outside the 1% window the supplies will not current share satisfactorily. Figure 15. Current Sharing Block Diagram equipment used in hazardous environments, or nuclear control systems. date manufactured. Specifications are subject to change without notice.
