When ordering, suffix the following option mark to the model number.
<e.g> DJOP60-1-LDS (Alphabetical order)
Rise time
Capacitative load
Capacitative load may cause oscillation.
In such cases, placed a power resistance in series with the output.
Be careful that the frequency bandwidth is limited depending on the resistance and
capacitance placed in series when capacitative load.
Inductive load
Some inductance of inductive load may cause resonance in CC mode.
In such cases, connect a C-R series circuit between output terminals to prevent resonance.
Response speed
When accurate output waveforms are required, select a amplifier with a frequency
bandwidth higher enough than the operating frequency.
In case of using sine waves, 3 to 5 times more frequency bandwidth is required, and around
10times more in case of square waves in general. Inadequate bandwidth causes not only
decrease in the output amplitude but much difference between the input and output phases.
Therefore operating the product while monitoring the actual output waveforms is
recommended.
(Stepping time): The response time is sometimes described by the rise time (as shown
in the drawing on the right).
The rise time of an amplifier at a response speed of (= frequency bandwidth) Fc (Hz)
is generally acquired by "tr
0.35/fc."
Fall time tf is the same as tr.
Frequency bandwidth
: at 30kHz or lower, tr = tf = around 12 µs
: at 20kHz or lower, tr = tf = around 18 µs
