Description
While the ED50, ED100, and ED250 share the same physical \”Contur\” design (meaning they all look identical from the outside with the same 70mm slim header), the internal drive power and logic are what separate them.
Think of them as the same car body with three different engine sizes.

Specific Variations Explained
-
ED50 (The \”Lite\” Version): * Designed strictly for Low Energy ADA applications.
-
It is physically lighter and lacks the \”Full Power\” motor capabilities of its bigger brothers.
-
Pro Tip: It cannot be upgraded to \”Full Power\” high-speed operation.
-
-
ED100 (The \”Versatile\” Version): * The most common unit in Canada.
-
It is a \”hybrid\” that can be toggled between Low Energy and Full Power using the Blue Upgrade Card.
-
Ideal for high-traffic interior doors or standard-sized exterior storefronts.
-
-
ED250 (The \”Heavy-Duty\” Version):
-
Contains a much beefier 240W power supply and a stronger gearbox.
-
It features Wind Load Control, which uses sensors to detect if the door is being blown open/shut by Canadian winter winds and automatically adds motor torque to compensate.
-
The \”One System\” Concept
Dormakaba advertises them as one product because they share:
-
Uniform Aesthetics: The same slim 2-3/4\” (70mm) height across all models.
-
Identical Mounting: Use the same drilling templates and arm assemblies (Standard Push or Slide Track Pull).
-
Modular Logic: All use the same basic control board, with \”Upgrade Cards\” (Fire, Full Power, Professional) used to differentiate features rather than changing the whole unit.
