FAQs
- How should I choose a circuit breaker for a high-power DC power supply?
- Can we use multiple thin wires to connect the power supply to the load instead of thick wires?
- We are concerned that the output terminal is equipped with a metal cover. Is it safe to use it as it is?
- What precautions should be taken for parallel connection of the power supplies?
- Do you have any tips for extending the service life of power supplies?
Options
- -LF
-
Floating ground (withstanding voltage of 50 Vdc)
Used when measuring minimal current in the load. All equipment that connects to the Remote Control Connector (TB1) must be on the floating ground in case this feature is intended to be used.
(Cannot be used for the purpose of floating REH series.)

Optical Interface port
This option changes the standard interfaces to a built-in optical interface port. By combining this option with an adapter for optical connection (sold separately), communication between the control device and the power supply can be controlled in an isolated state. Be sure to select this option when using the product in the following environments.- -LGob: Optical interface port + optical cable 2 meters
- -LGob(Fc5): Optical interface port + optical cable 5 meters
- -LGob(Fc10): Optical interface port + optical cable 10 meters
- -LGob(Fc20): Optical interface port + optical cable 20 meters
- -LGob(Fc40): Optical interface port + optical cable 40 meters
Select the optional optical interface board (-LGob) when using this DC power supply under the following conditions.
- Noisy environments such as factories (example: when motors or coils are used near loads or power sources).
- If this power supply and your controller (PC or PLC) cannot be installed within 2 meters.
- When there is a possibility of arcing or output short-circuit.
The optical communication adapter at the control side should be purchased separately.For details, click here.

- Optical isolation adapter
-
To use the optical interface, you need to prepare an optical interface adapter separately. The following interface adapters are available according to your controller port.
- CO-E32: LAN to optical interface adapter
- USB-OPT: USB to optical interface adapter
- CO-OPT2-9: RS-232C (9 pin) to optical interface adapter
- CO-OPT2-25: RS-232C (25 pin) to optical interface adapter
- CO-OPT4-25: RS-485 (25 pin) to optical interface adapter
- CO-G32: GPIB to optical interface adapter (Scheduled for discontinuation in December 2028)
