APPLICATIONS
Various research and development
As a power source for automatic inspection systems, etc.
* The common side and the +output terminal are set to the same potential. Please use the floating control voltage without grounding, or set the common of your equipment to the same potential. If you do not follow it, the power supply cannot be controlled properly and may cause malfunction. When using a multi-channel Programmable Logic Controller (PLC) or non-isolated PLC, note that there is a possibility of connection to other device grounds through the PLC.
Sink current 1mA
Logic of OUTPUT can be made reverse.
Output control
(Voltage, Current, Overvoltage protection, Overcurrent protection)
Output monitor

* Output control external signal should not be grounded but floating potential. + output terminal and common become same potential. Power supply can not be controlled or could be damaged if common is grounded via way of customer's equipment. Please be aware that external control voltage signal could accidentally be connected to the ground of other equipment in case, for example, multi-channel, non-isolated PLC is in use.

Example of Connection and Operation
Using the same multiple units of R4G/R4GN series, the output voltage and output current can be increased by connecting the outputs in series or parallel. Moreover, the synchronous operation and the master/slave operation with -LGmb option are also available. Note: The common of the external Input/output control connector (TB1) is connected to the +output in the R4G series and the -output in the R4GN series. Do not connect the commons of the external Input/output control connector to each other.
Series connection
The total output voltage is up to 250 V.
The output voltage exceeding 250 V is unavailable in series connection.
The output current will be the smallest value.
Parallel connection
Use the same value for voltage setting in parallel connection.
The output current is the sum of each current.
In order to prevent damage, set the OVP level of all the power supplies to the maximum.
