Ultra-thin 35mm-width for space saving and light weight
In conducting evaluation tests of small systems like batteries or power supply circuits, you will consider load device in a compact design.
Features
Perfect space saving with an extremely compact, lightweight body to suit any customers' space for installation
While the number of units installed on a 19-inch rack was limited up to about only five as multiple units so far, the EGS units can accept as many as 10 units in even smaller spaces than usual.
A maximum of ten units are available on a 19-inch 3U-size rack.
Rack-mount holder RMO series
The multiple AC input lines are neatly collected into one!
* Please refer to the "RMO series" brochure for details of the dedicated adapter.
