DESCRIPTION

The GS-R28.0BE is a switch mode constant volt-

age BATTERY ELIMINATOR that can deliver an

output voltage of 7.5 V at 0,75 A of DC output

current (Peak output current = 1.8 Ap).

Two versions of the INPUT PLUG ADAPTOR are

available:

WASHER TIP VERSION:

GS-R28.0BE-E (Ordering Number)

SPRING-LOADED TIP VERSION:

GS-R28.0BE-A (Ordering Number)
