Functions
Flexible Current Limit and Protection: CC Control & OCP turn-off SYSTEM
The HARS series offers both Constant Current (CC) control and Overcurrent Protection (OCP). By configuring the set points for each, you can define the desired behavior. Set the CC level to actively limit the current by voltage droop, or set the OCP threshold to cut off the output completely for protection. This dual-functionality provides flexible and reliable control over the output current.
Protection by Arc Trip
Arc discharge count Protection
The HARS series makes it easy to protect your power supplies with its advanced arc count & monitoring function.
There are two methods to set the output stop:
-
(1) Arc Protect Count:
The output is turned off when the output current surpasses the arc count limit.
Arc count (1) setting screen Maximum arc count: 9999
-
(2) Arc Protect Count and Time:
The output is turned off when the output current surpasses the arc count limit within a defined time frame.
Arc count (2) setting screen Maximum arc count: 999
Maximum of arc protection enabling time: 59 m 59 s
Pulse and Ramp Sequence Functions
Program output patterns without a computer
* Note: The output cannot follow the set value if the programmed time is shorter than the unit's rise time (Tr) or fall time (Tf).
A. Pulse (Step) Sequence
The Sequence function allows users to program voltage and current patterns by cycling through settings stored in memories a, b, and c. The sequence can run continuously or for a specified number of cycles. This eliminates the need for external computer control during simple repetitive tests.
B. Ramp Function
The Ramp function linearly increases or decreases the output to a set voltage or current over a specified time (t1, t2). This is essential for applications requiring gradual power-up or power-down to protect the load.
* Ramp operation targets: Voltage & Current, Voltage Only, or Current Only.
C. Combined Sequence and Ramp
For advanced control, the Sequence and Ramp functions can be used together. This allows you to create complex profiles by smoothly ramping the voltage and/or current between the discrete steps defined in memories a, b, and c. The entire waveform can be run continuously or for a pre-set number of cycles, making it a powerful tool for various testing scenarios.
External analog remote control
-
External output ON/OFF
The output can be turned ON/OFF by relay or TTL signal. -
Remote/Local change
As for the output voltage control, output current control, overvoltage protection, and overcurrent protection, the remote/local mode can be individually switched by relay or TTL signal. -

HARS Series Options
Select the option that works best for your enterprise.
-LF
Floating Ground
For measuring the current in load. (Able to withstand voltage of 50 Vdc)
For devices that connect to a Remote control connector (TB1), -LF requires floating ground.
*This option cannot be used to float the high voltage power supply itself.
-LGob*
Optical Interface Port
This option provides an optical interface port for isolated communication. Optical fiber ensures complete electrical isolation between the power supply and the controller, preventing malfunctions caused by transient surges, lightning induction, and external noise.
- -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 optical interface option (-LGob) for the following conditions:
- Noisy environments, such as factories with motors or coils operating near the power supply or load.
- Installations where the distance between the power supply and controller (PC/PLC) exceeds 2 meters.
- Applications with a high risk of arcing or output short-circuits.
A separate adapter (CO/USB series) is required for control via digital interface.
-LRs*
RS-232C/RS-485 interface port
(only 10 kV or less models)
Using RS-232C/RS-485 communications, output controlling and operation status monitoring of these devices can be performed.
-L(230V1P)
Single-phase input
(2000 W or more models)
-L(0m)
Without output cable
Output cable not provided.
If you require a cable longer than 2.5 meters, please select this option and purchase an output cable separately.
*Only one option may be chosen at this time.
How to Order
When placing an order, please add the option code(s) after the model name. If adding two or more options, omit the “-L” from the second and subsequent option codes, and list them in alphabetical order, with the parentheses option placed at the end.
Example: HARS-1P500-LFRs, HARS-1P500-LFGob(Fc10)(0m)
Accessories
Optical isolation adapter
Adapters for connecting 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.
- 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 (Discontinued in December 2028)
