PD2
Is there a table that compares the PD2-3024 Series and PD3-3024 Series units?
A table comparing the PD2-3024 Series and PD3-3024 Series units is given below.
(Common specifications for PI, SI, and EI.)
QA No. 12-0001
Since the frequencies are different and the FET gate voltages are different, they are not completely compatible with each other.
Additionally, linearity is roughly equivalent for both series units.
QA No. 11-0144
Are there any noise related issues for the PD3 Series?
Since it depends on the usage environment, although it is hard to say for sure, since the units for this series perform external control using photo coupler input and they are equipped with noise suppressing countermeasures based on the techniques we have refined over the years, it is fair to say that they are more resistant than the PD2 Series.
QA No. 11-0143
When installing the PD2 and PSB units, is it possible to stack them on top of each other?
They are not designed to a specification that allows for stacking on top of each other.
Please do not use them in a stacked arrangement.
QA No. 11-0102
What are the differences between the PSB and PD2 units?
QA No. 11-0101
It is possible to use it in this way.
If the signal ground line and the ground line used by the customer is connected with each other, it is possible to extract the signal from the over-current protection pin.
When doing so, please leave all other pins unconnected and open.
QA No. 11-0099
Please use a ceramic capacitor.
(Please use it in an environment that is free from the effects of noise.)
QA No. 11-0098
There is no problem if the unit is used with the attachment hole on its left side facing down.
If the unit is turned with the left side facing up, the circuit board will be on top, resulting in poorer heat dissipation due to the positioning of the switching Control Unit, etc., underneath it, and there is a risk that it will not be able to supply the specified output.

| PD | Channel 4, 8...1.5kOhm |
| PD2 | Channel 1, 2...4.7kOhm |
| PD2 | Channel 4, 8...2.2kOhm |
QA No. 11-0096
Since it is a negative logic output, when the signal is "0," the voltage level will be "high."
"ExtMode" switching can only be performed using the lighting ON/OFF signal.
QA No. 11-0095
Internal and external switching setting will apply to all channels.
QA No. 11-0094
They are internally connected. Either one can be used without any issues.
QA No. 11-0093
The ON/OFF response time is approximately a minimum of 10μs.
(This may vary for custom order power supplies.)
QA No. 11-0092
Since the unit is designed with fastening screw holes, please be careful to mount it properly.
As there are restrictions we ask that you inquire further with our sales representatives.
QA No. 11-0091
We apologize as we are unable to provide you with a AC 200V cable.
We ask that you prepare one that matches your own usage environment.
QA No. 11-0090
The fastening screw holes are located on the bottom and side surface. However, only some products for this series feature screw holes on the side surface.
Additionally, the screw holes on the bottom surface are in a location where they are hidden from view by the rubber feet.
QA No. 11-0089
The adjustment knob for our PD2 Series unit is broken. Can we purchase another one?
We offer repairs for such cases.
Please inquire further with our sales representatives.
QA No. 11-0086
After adjusting the camera shutter, please input an ON/OFF trigger signal.
Please note, however, that it is not possible to completely synchronize camera and lighting.
QA No. 11-0085
This type of usage is not possible.
QA No. 11-0084
The maximum allowable voltage is 5.5V.
QA No. 11-0083
There is no correlation.
QA No. 11-0052
There is no conversion cable.
QA No. 11-0050
The total output power, is the sum total of power being output at the same time on channel 1 and channel 2, and it can reach a maximum of 28W
(maximum power for each single channel also amounts to 28W).
