How to supply the DC power to our iSW DM25DB 24V and iSW DM25CE 12V tubular motors, for the single individual user, there are many solution, you can use our DC1686A single-channel DC RF Receiver for DM25DB motor, you can use 12V power adaptor or 12V Rechargeable Battery Wand DC224G for DM25CE motor, but if you need to supply DC power to multi DC tubular motors, there is another way to achieve this, it's easy, convenient ,cost effective and very practical and effective particularly for the new build home which this solution not only can supply the DC power, but also it help you to pre wire the Network Data cables to every room.
AS you know, we can send the power over Ethernet (PoE), basically it uses wires 4, 5 are positive and 7, 8 are negative or ground as positive and negative of the power supply and the other 4 wires carry data (1,2,3,6), both of our iSW DM25DB and iSW DM25CE are non-PoE standard devices, so we have to use passive PoE Injector or passive PoE Switch ,you can't use active PoE one.
There are some good product we can use, the good example is:
This product doesn't come with External Power Supply, so you need to according to your requirement to choose the power supply. Because the rated current of both of our iSW DM25DB and iSW DM25CE motor are less than 1A, and the rated power are 9.7W and 10W, so for the 12V one, we can choose 12V 8A power adaptor and 24V one, we can choose 24V 4A power adaptor would be fine. If you are going to supply the DC power to different room (location) and you don't need to operate all of 8 tubular motors in the same time, then you can just choose the less power PoE kits or less power External Power Supply, that would be fine, such as: you can use :
TO operate with our iSW DM25DB 24V motor, of course due to 25DB motor hasn't built in receiver, then you can combine it with our Qubino Flush Shutter DC Z-Wave Plus DC power roller blinds controller or our DC128 Single manual switch to control the tubular motor.
For the new build home, you can sent the Network Ethernet Cable ( Cat6 cable) from this Multi Port passive PoE Injector which you can install it in the Network Enclosure to every location which you need to supply the DC power to the motor, these location can be a network data wall switch which the PoE splitter Lan port will connect to, from there, you need to pre wire a Twin Core Wire 0.5mm2 (20AWG) cable from the wall switch to the top corner of the window frame. The advantage of this is it not only supply the DC power to the DC motor, but also provide you the extra Lan Port for your wired network, the downside of this is it only provide you 10/100 megabit Data speed at the moment. The other way is you can pre wire the network data cable ( Cat5E cable would be alright) to the top corner of the window frame, it will provide you DC power directly after the PoE splitter, in this case, you do not need to put both of the Cat5E cables into the Lan port of the Injector and Lan port of the Splitter.
You can simply use Multi Port passive PoE Injector and POE splitter to supply DC12V or DC24V power to our iSW DM25DB and iSW DM25CE tubular motors like they can supply the power to IP Cameras, IP Phones, WiFi Access Points via PoE. It's low voltage DC project, you simply can DIY.
