功能特性
• Basic Waveform Generation：DOSF is equipped with a built-in function generator that produces basic waves such as sine, rectangular, and triangle waves. The frequency range can be set between 1 Hz and 200 kHz. You can adjust amplitude; start phase (for sine wave), on-phase control (for sine wave), and duty ratio (for rectangular/triangle wave). Start phase (90 deg) On-phase control (+90 deg) On-phase control (–180 deg)
• Application：Power activation test, Inrush current measurement, waveform fluctuation test
• Sequence Functions：The DOSF series is equipped with programmable sequence functions, including step time, amplitude ramp, CV/CC mode switching, frequency sweep, AC superposition, step jump, and jump times. These useful functions help to program the desired waves in a very flexible manner, enabling the support of laboratory and research work efficiently. If amplifier's output turns off while it is running a sequence
•Applications：Testing of motors, Pulse power supply and Various evaluation
• Measurement Functions：The DOSF series is equipped with measurement functions that measure DC value,AC (RMS) value,maximum value,and minimum value. Thus,Wide frequency ranges,from DC to 200 kHz,can be measured automatically,and it is easy to change the settings depending on the application. [Example] measure AC waveform [Example] measure DC + AC waveform
•Memory Functions：During fundamental wave operation, output voltage (in CV mode), output current (in CC mode), CV/CC setting,and waveform setting can be saved in 10 setup memories. As sequence programs can be saved in up to three,it is useful when using frequently used multiple waveforms or sequence operations. Other functions:DOSF is equipped with Protection function,Key-lock function,and CV/CC switching,as

选件 / 附件
• -LD：Interlock
• -LEt：LAN interface port *
Enable digital control via LAN
[Control items]
Output ON/OFF, Voltage/Current setting (AC and DC), Switch of constant voltage/constant current, Frequency setting, Waveform setting (sine wave, square wave, and triangle wave), Phase setting (sine wave), Duty setting (square wave and triangle wave)
• -LF：Floating ground (withstanding voltage of 200 Vdc)
The negative terminal of the output can float up to 200 V. However, please take note that the external control signal source (such as a function wave generator) and the common measuring device that connects to the amplifier's monitor terminal will also become floating potential in this case.
• -LGob：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 port (-LGob) when using the bipolar 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 an output short-circuit.

• -LMsm: Master unit for master-slave control
-LMss: Slave unit for master-slave control：By connecting a master unit and slave units with dedicated control lines, the master unit can control all slave units simultaneously. Parallel connection allows for increased current capacity. Up to three units in total can be connected: one master unit and up to two slave units.
Note: Precautions for using the master-slave operation
Only the master-slave connection is available for the same model.
In parallel operation, the frequency range is narrower.
It can also operate as a standalone unit.
Factory adjustment is required when changing the master-slave combination.
Either communication option (-LEt, -LGob, or -LUs1) is necessary for only the master unit when the power supplies in the master-slave connection are controlled by digital communication. However, if you want to perform digital communication control on the slave unit alone, these options are also required for the slave unit.
