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)
