Control Units
PSB
There are no issues.
(Although the maximum power consumption will drop to around 80 to 90%, when used in an environment 40°C or higher, since the specifications only allow usage in environments of up to 40°C, this should not be an issue.)
QA No. 11-0123
For light units that have 4 or less LEDs per circuit, they will still stay illuminated even when the dimming volume knob is set to the minimum level.
QA No. 11-0122
When using a PSB Control Unit, is it possible to get a readout of the configured numerical values?
It is possible if a modification is performed to install a multi-rotation volume knob equipped with a dial.
QA No. 11-0121
Although this is possible, please note that there will be a delay in illumination amounting to a sum of the relay response time and the start-up time of the Control Unit (0.5 seconds typ.).
Additionally, there is also a possibility that when the light units are turned off, they will continue to remain illuminated until the Control Unit capacitor is allowed to sufficiently discharge its stored electrical charge.
If a relay signal is input on the Control Unit output-side rather than the AC input side, it is possible to reduce this lag so that it equals the response time of the relay.
For cases where ON/OFF switching is being performed on the AC input side, with the aim of preventing relay contact degradation caused by inrush current, we recommend using an SSR equipped with zero-crossing detection.
At the same time, please note that since the Control Unit internal fuse has a service life of only 100,000 cycles, we do not recommend using it for applications that require frequent ON/OFF switching.
QA No. 11-0120
What is the response time for external ON/OFF switching for the PSB-EX type units?
PSB-EX Control Unit external control ON/OFF switching is as follows:
10μs when switching OFF to ON
300μs when switching ON to OFF
QA No. 11-0119
Is it possible to perform external dimming when using a PSB Control Unit?
External control is not possible for a standard model.
We offer models that are capable of this as custom order products, and we ask that you contact our various sales offices for details.
QA No. 11-0118
Are there any EC Directive compliant models for the PSB power supplies?
We offer EC compliant models for this product.
We have obtained CE markings for them, and their input voltage is AC 100 to 240V.
There are 2 types of compliant units, and you can select whichever one matches your application.
Model name: PSB-1012V-WW (output 12V/10W)
Model name: PSB-1024V-WW (output 24V/10W)
Moreover, please note that the included AC cord can only be used with power sources up to 125V.
If you need to use the units at a higher voltage, we ask that you prepare such cables on your own.
QA No. 11-0117
Is the PSB Control Unit equipped with a fuse?
Input over-current protection:
-The internal switching Control Unit is equipped with a melting-type fuse
Output over-current protection:
-Over-current protection activates when a minimum of 105% of the rated current is detected, and the unit is self-recovering
QA No. 11-0116
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.

What are the differences between the PSB and PD2 units?
