Key Features & Typical Use
Charging Where the Socket Format Is French
The number of sockets that are designed according to the German standard is large, while those according to the French standard are considerably fewer, which is why establishments in France need to use adapters. However, the SD3B-020 employs a Type E socket face that has its own earth pin feature that allows charging using only one module.
Specified across a Property Rather Than a Room
Hotels and apartments get their charging sockets installed based on their schedule; therefore, charging sockets are commonplace in these places. The fact that the module shares a common panel, frame, and case design with a standard French socket entails that the installation process remains unchanged.
The Adapter Problem, Solved at the Source
The people behind the manufacturing of adapters lose and distribute them, leading to the idea that comfort comes at a recurring price. The point for charging electric vehicles installed within the socket cannot leave the premises, meaning the requirement indicated in both the standard and norms will apply for the duration of the installation period and acquisition of items will be unneeded.
Wide Plate through the Room
Devices are all integrated in guest rooms: power outlets, controls and data sockets are in one unit at the bedside and the work area. Since all these appliances are mounted on a plate of size 859 x 760mm, it creates an impression of a single structure.

SD3B-020 – Bringing French Standard Properties Up to How Rooms Are Used
The guest room, which was initially created for only two outlets, now has to accommodate not only two phones, but also a tablet, a laptop, as well as the kettle and the lamp. In the French standard market, it has traditionally been difficult to find the charging sockets that would satisfy these needs, which is why the use of adapters has become the norm. Integrating the charging ports into the Type E socket module creates a solution to both these problems.
For an operator, what is important is standardisation. The module is defined once for its functionality, appears in exactly the same way in any room, and does not change there. It can be used without the need to supply new charging points, making sure there is no difference between them and the sockets next to them. In a situation where a brand wants fast charging feature at the room level, SD3B-021 implements 20W power level on the same computer.

Frequently Asked Questions
Is a French format charging socket available?
To be confirmed, but this product has been designed to provide Type E socket that has USB-A and Type-C charging at 5V 2.1A in a format of an 86 x 76mm panel. USB-A and Type-C charging outlets in French format are relatively rare compared to those in German format; that is why such a module is available.
Can it be specified across a whole property?
Correct, and that is the purpose of the equipment. The module shares its panel, housing and frame with the non-technical French plug, which means that a property can use the charging version in rooms while ensuring that there is no disruption in installing it or changing the plate style.
What charging rate does it provide?
5V 2.1A, the normal charging level for the range. When a brand or a project requires fast charging in some classes of the room, SD3B-021 offers the same socket with a 20W output on the same panel.
Does the earth pin arrangement change?
No. The device has the French Type E design where the grounding pin can be fitted within the socket while the functioning of the connectors and the devices remains to be the same as that of the standard French outlet.
Can the socket and charging ports be used together?
Because of its design, the charging circuit is not dependent on the mains socket. Therefore, and appliance can be used while the phones and tablets are connected to the USB ports for charging.
Can it be supplied with the rest of the property’s devices?
Yes. All of the devices in the SD3B range share the same format and system of construction, which allows the schedule to be delivered at the same time. It should be noted that the minimum order quantity is confirmed for each item in the quotation.
