Examples of Applied Operation
R4G series, the output voltage and the output current can be increased by connecting the same models in series or parallel operation. As to the control, the use of one control in parallel operation or digital master/slave control in –LGmb option is available. External I/O control connector (TB1) is connected to the positive output for R4G, and negative output for R4GN so do not connect more than two power supply units.
Series Operation
Sum total of output voltage is 250 V. Accordingly, ones of exceeding 250 V its output voltage can not operate in series. Output current is one of the smallest power supply.
Parallel Operation
Make all setting voltage the same value. Output current is sum total of one of each unit. Then, make OVP level of all power supplies the maximum to prevent damage.
Split Operation
+ and – output are possible.
