Operations
Examples of Applied Operation
R4G can be enhanced in its output voltage or current by hooking the same type of units in series or parallel. And one control parallel operation or digital master-slave with optional -LGmb is possible. Do not connect together COMMON of two and more units because the COMMON of the connector for external input and output control (TB1) is connected to +output (in case of optional -LNcn selected, -output).
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.
