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

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.

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

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

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

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

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.
