Functions
Direct Control of Bipolar Power Supplies
If a different output is used instead of DC, 0 V, and 0 A will be displayed since the unit is dedicated to displaying DC output in DOS series
Output value from the function generator can be converted and set based on our bipolar power supplies.
Accordingly, eK-FGJ features an accurate and intuitive setting without calculating with the gain value.
Dual-Channel Synchronous Waveform Output
Reverse-phase synchronous output for motor and dielectric driving By driving two power supplies in reverse phase (positive and negative), the system can effectively drive motors or test dielectric materials.
Synchronized 2-Channel Control The series provides synchronized 2-channel outputs. Both channels can share the same waveform, cycle, and sweep start point. Additionally, a precise phase shift can be applied between the two channels.
Controls two waveforms by synchronizing their cycles and sweep start points.
Adjusts the output timing by setting a precise phase difference between channels.

Software
Intuitive Control Software Included
The eK-FG2 comes with dedicated control software that enables programmable operation and complex waveform generation.
Sequence Function
Independent sequencing is available for both Ch1 and Ch2. Users can program specific output patterns or utilize custom waveforms created in the dedicated editor.
Optional Waveform Generation
Arbitrary Waveform Generation: Create complex waveforms effortlessly by combining base waves (e.g., sine, square) using mathematical functions (add, subtract, multiply).
Flexible Composition: Define specific ranges for waveform modification.
Arithmetic Operations: Combine waveforms to generate positive or negative outputs tailored to your application requirements.
(Note: Reproduced waveforms in the software may slightly differ from the actual physical output depending on load conditions.)
Options
- Optical Interface Port Option
-
Isolation control is performed by optical communication. The optical interface option provides complete electrical isolation via a fiber optic cable. This prevents measurement errors and malfunctions caused by surges, induced lightning, and other external noise. (can be produced with the control software).
Important Note on Optical Interface Response Time
The optical interface option (-LGob) provides superior noise immunity but may introduce a communication delay before the start of sequence operations or arbitrary waveform output. This option is not recommended for applications requiring immediate response or high-speed synchronization between the command and output.- -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 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.
When this option is selected, a standard USB port will not be installed.
How to Order
When ordering, add Option No. in the following order to Model No.
