Ultra Low Profile and High Power! Programmable DC Power Supply
- Output voltage: 10V to 650V
- Output current: 1.2A to 1200A
- Output power: 0.75kW to 15kW
- Wide selection of models
The RE Series is a family of compact, high-power, and highly efficient programmable DC power supplies, made possible by our proprietary switching technology.
With minimal heat dissipation and a footprint up to 1/10th the size and 1/20th the weight of conventional power supplies, the RE series enables high-density mounting. Its low power consumption reduces operating costs and supports environmental sustainability.
Extensive remote control and monitoring functions are included as standard. An optional digital interface allows for seamless integration into a wide range of systems. Select the ideal model for your application from a comprehensive range of over 140 models, with outputs ranging from 10 V to 650 V and 0.75 kW to 15 kW.
Power is expandable up to 60 kW with the master-slave feature. (UL Certified)

Functions
Remote control connector (TB1)
* Please use TB1 in floating as TB1 and negative voltage output is connected in the internal part.-
REMOTE/LOCAL change
As for the output voltage control, output current control, and overvoltage protection, the remote/local mode can be individually switched by relay or TTL signal. -
External output ON/OFF
Output can be turned ON/OFF by relay or TTL signal.
The logic of the signal can be selected by entering 5 V. - Output voltage control
- Output current control
- Overvoltage protection
- Output monitor (Voltage, Current)
-
Output of status
Common is floating with the output of the open collector for each COMMON.
Function setting switch (SW1)
-
Output voltage control
0 to 10 V Local ⇔ 0 to 10 kΩ approx. -
Output current control
0 to 10 V Local ⇔ 0 to 10 kΩ approx. -
Overtemperature protection
Manual reset ⇔ Auto reset -
Output state auto-recovery prevention (former: power failure protection)
ON ⇔ OFF (ON/OFF by AC)
Remote sensing
Prevents voltage drop-down (Vo-VL) due to resistance (R) or deterioration of stability by contact resistance (Max 0.5 V)
Output terminal
The form differs depending on the MODEL. Please check which form is in dimension.
* To an output terminal cover for terminal board models, two places of holes of 8 mm in diameter are arranged as standard specifications.
A diameter bigger than 8 mm is also available.
Please contact our sales office for details.

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
- -LCP *2 *3

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 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 build-in optical port (-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.
To use the optical interface, you need to prepare an optical interface adapter separately. For details, click here.

Isolated remote control
Output control signal is isolated from common (=outputΘ) so that floating of the control signal is not required when negative output operation or series connection
(isolation voltage from outputΘ is below 250 V)-
Output control
[-LIs] CV: External control voltage 0 to 5 Vdc, CC: External control voltage 0 to 5 Vdc
[-LIs10] CV: External control voltage 0 to 10 Vdc, CC: External control voltage 0 to 10 Vdc -
Monitor output
[-LIs] Output voltage monitor: 5 V/Maximum output voltage, Output current monitor: 5 V/Maximum output current
[-LIs10] Output voltage monitor: 10 V/Maximum output voltage, Output current monitor: 10 V/Maximum output current -
Other functions

-
Output control
- -LLp
-
10-turn potentiometer with lock (both voltage and current)
Only for models less than 300 V
- -LOcp *4
-
Overcurrent protection (OCP)
Cut off the output at the set current value. Local setting only.
Setting range: 5% to 110% of maximum rated current, Local setting: 1-turn volume on front panel
Reset: Manual recovery by OUTPUT switch or External output ON/OFF
- -LPfc *4
-
Power factor correction circuit (Three-phase input of 3.75 kW to 15 kW type only)
Size of the case will be different. Contact the nearby sales office for more details about this option.
- -LUs1 *1
-
USB interface port
- -L(220V)
-
Input voltage: 220 Vac ±10%
For 0.75 kW to 1.2 kW models, Change the original input voltage of 230 V to 220 V. Input current will be about 105% of typical value
- -L(230V)
-
Input voltage: 230 Vac ±10%
For 1.8 kW to 15 kW models, Change the original input voltage of 220 V to 230 V. Input current will be about 95% of typical value
- -L(240V)
-
Input voltage: 240 Vac ±10%
For the original input voltage of 220 V models, Change the input voltage to 240 V. Input current will be about 95% of typical value For the original input voltage of 230 V models, Change the input voltage to 240 V. Input cur rent will be about 90% of typical value
- -L(400V)
-
Input voltage: 400 Vac ±10%
For 7.5 kW to 15 kW models
The size of the case will be different. Contact the nearby sales office for more details about this option.
- -L(440V)
-
Input voltage: 440 Vac ±10%
For 7.5 kW to 15 kW models
The size of the case will be different. Contact the nearby sales office for more details about this option.
- Only one of these remote control options can be selected. If you are considering digital control from a computer, we recommend selecting the optical interface (-LGob), which is resistant to noise, and using it with our separately sold adapter.
- The constant power control option (-LCp) cannot be selected together with any of the remote control options (-LEt, -LGb, -LGob, -LIs, -LIs10, -LUs1).
- The constant power control option (-LCp) and the overcurrent protection option (-LOcp) cannot be selected simultaneously.
- -LPfc and -L(400V) or -L(440V) cannot be chosen simultaneously.
How to Order
When placing an order, please list the option symbols after the model name in alphabetical order. When selecting multiple options, omit “-L” from the second and subsequent option symbols. The option for changing the input voltage should be listed last.
<Example> RE15-250-LGob(Fc5)LpPfc(240V), RE100-100-LCpIs10LpOcp(400V)
Please ask our offices for a Three-phase AC input cable.
Optional Add on Program for Build-in Digital Interface
- Sweep control program for -LEt, -LGb, -LGob, -LUs1
-
This program is used to gradually change the output of DC power supply that can be controlled by our power supply digital controller CO-HV. Any settings are provided as for the voltage/current values when the output starts and reaches, and after the output starts. Following that, the output is activated accordingly. It is very convenient for such applications like transformation process of the capacitor, aging of electronic components and burn-in testing of semi-conductor etc.
where it is necessary to repeat the output by changing the output gently and a decided pattern.For more specification details, download the datasheet below.
