Functions
Fundamental waveform generated function
The DOPF is equipped with a built-in function generator that produces sine, rectangular, and triangle waves. The frequency range can be set between 0.01 Hz and 20 kHz (30 kHz is available for some models). In addition, the easy adjustments of amplitude, start phase (sine wave), on-phase control (sine wave), and duty cycle (rectangular function, triangle wave) are possible, making it very convenient for a variety of evaluation tests and applications.
Applications: Power-on test, rush current measurement, wave fluctuation test, etc.
Sequence functions
DOPF is equipped with a sequence function that can program step length, step amplitude, ramp, CV/CC mode, sequence-ending setting, AC superposition, step jump, number of jumps, etc. Any desired waveform can be generated making it useful for various experiments, evaluation, and validation applications.
If the amplifier's output turns off while it is running a sequence program halfway through, the leftover sequence will not run but it is re-activated from the beginning of the original sequence.
- Step time: 10 ms to 1999 s 999 ms (resolution: 1 ms), Ramp and AC waveform is 50 ms
- Up to 16 steps per program and settings for 3 programs can saved
- Can be set CV/CC mode per program
- Frequency: Infinite, 1 to 999
Complicated waveforms such as below can be easily generated just by using the sequence function.
Applications: motor testing, Pulse power supplies, or Various evaluation equipment, etc.
Measurement functions
DOPF is equipped with measurement functions that measure DC value, AC RMS value, Max value, and Min. value. Thus, wide frequency ranges, DC to 20 kHz, can be measured automatically, and it is easy to change the setting depending on the application.
Besides, there is no need to choose options, and it is easy to change the settings depending on the application.
Memory function
DOPF is equipped with both preset and set-up memory.
During fundamental wave operation, output voltage (at CV mode), Output current (at CC mode), CV/CC setting, and waveform setting can be saved to 10 set-up memories. Also, sequence programs can be saved in up to 3 programs, which is useful for operations regarding multiple waveforms more often used or sequence functions. Data changes can be saved and data called out very easily.
DOPF is also equipped with a Protection function, Key-lock function, and CV/CC crossover, as standard.

Optical interface port
With optical communication, isolation control is performed. As complete isolation is performed by means of optical fiber, this enables advanced prevention of erroneous operation involved with transient phenomenon caused by surges, inductive lightning, external noise, etc.
To use the optical interface, you need to prepare an optical interface adapter separately.[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) (The converters are required sold separately. Please contact our sales staff for details.)

- -LGob(Fc20): Optical interface port + optical cable 20 meters

Select the optional optical interface port (-LGob) when using this DC power supply under the following conditions.
- Noisy environments such as factories (for 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.
- -LMsm: Master machine for master-slave control
-LMss: Slave machine for master-slave control -
By connecting a master machine and a slave machine with dedicated control lines, the master machine can control all slave machines at once. Parallel connection can increase the current that is insufficient for a single operation. 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 master-slave connection is available for the same model.
- In parallel operation, the frequency range is narrower.
- It can also operate on a single.
- 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.
