Schurter Introduces a Series of Power Entry ModulesApril 20, 2021 by Gary Elinoff
The devices consist of an IEC C14 appliance inlet with cord retention, a fuse holder and a mains switch
Schurter’s DD11 power entry modules feature a horizontal flange for greater mounting options while still taking up minimal space, giving the device wide ranging applicability in the area of pluggable power supplies. They conform to IEC/UL 62368-1 and are designed to accept IEC C14 power cords

Expanded Options for Mounting
The flange allows members of the 18 unit family to be solidly mounted to the enclosure’s wall, allowing optimum contact with the appliance unit and thus increased protection for the applications. The newest unit features a horizontal plastic flange that also serves to minimize the installation’s height.
Well suited for applications where space is at a premium
Because the DD11 series secures the C14 plug and includes both switching and fusing within one module, they are well suited for use in tight spaced designs. They also stand up to tough mechanical requirements while carrying high electrical currents.
The DD11 series employ the V-Lock notch standard, which can be employed for 10 and 16 amp power inlets in accordance to IEC 60320.

In operation, a pin in the socket interlocks with a notch in the plug, mechanically locking the two together. When it is actually intended to remove the power cord, the locking is released by pressing on the releasing lever. There are various implementations of this mechanism.
Available Standard Versions
Standard devices feature two pole line switches and either one or two pole fuse holders. Customers can choose either illuminated or non illuminated versions, with a choice of red or green color. Versions with and without covers are available.
Other versions are specially available. Choices include:
2-pole fuse drawer, with shorting bar
1-pole fuse drawer, plus spare fuse case
1-pole line switch
Other rocker markings
All units operate at voltages and currents up to 250 VAC and 10 amps, respectively. This rating is at 50 Hz for IEC and at 60 Hz for UL/CSA
Dielectric Strength for 1 minute at 50 Hz:
- Greater than 2.5 kVAC between line and neutral
- Greater than 3 kVAC between line and protective earth
- Greater than 3 kVAC between neutral and protective earth
IP-Protection. The IP protection code describes the degree of protection a device affords from the penetration of foreign objects. For the front (exposed) side of the power entry modules, these units are rated to IP40 according to IEC 60529
- Members of the DD11 series function over a -25 to 85 °C temperature range
As mechanical devices intended to be employed by OEMs worldwide, these units are subject to a vast array of conditions and approvals from multiple international authorities. A complete description is provided in the datasheet. VDE and UL approvals are spelled out in detail. Three important compliances met are:
