Basic Operation
• The default communication method is USB. If other communication method
is selected, the related parameters need to be set. For detailed parameter
description, refer to 2.5 Remote Interface Connection.
• The instrument supports the non-standard RS-232 and GPIB interfaces, and
the configuration items in the menu are dynamically displayed according to
the interface user selected.
5.10 Set Parallel Operation Mode (Parallel)
This menu item is used to control whether the instrument is working in single
mode or in parallel mode. This chapter takes three instruments as an example
to describe how to parallelize the single units and how to return from parallel
mode to single mode.
The maximum power of this series power supply is 6 kW. The user can connect
power supply in parallel to provide a greater current and power capability. The
power supply is capable of connecting up to six units in parallel, reaching at
most 36 kW. The following figure shows three units connected in parallel, The
System Bus is used as connection between master and slaves.
Parallel connection is not recommended under PV simulation function.
Configure the Menu Item
1. Press the composite keys [Shift]+[P-set] (System) on the front panel to en-
ter the system menu.
2. Turn the knob to select the Parallel and press [Enter].
3. Press the Left / Right key or turn the knob to adjust the value of this
parameter.
• Single: Default value, indicates that the instrument is in single mode.
• Master: Indicates that the current single unit is set to master in parallel
mode. When set to Master, you also need to set the number of slaves to
be mounted for the master, so you need to set the value of the Total pa-
rameter. For example, setting Total = 3 means that the total number of
units in the parallel relationship is 3.
