INSTALLATION PRECAUTIONS
1. The Battery Saver Low Ripple is AC Input AND DC Output over-current protected
as follows:
> 120VAC 60Hz Input Fuse: 6.3 Amp
> DC Output: ATC, 25 Amp
Note: The external ATC 20 Amp DC OUTPUT FUSE is common to both the
Battery Saver output AND the vehicle battery connection that supplies power to the
load when the Battery Saver is OFF (120VAC to Battery Saver - OFF).
2. OVERLOADING the Battery Saver in excess of 20 amperes when the BSLR
is ON:
A. In excess of 20 amperes: initiate current limiting of the Battery Saver
output with a corresponding reduction in output voltage.
B. In excess of 30 amperes: causes the ATC 25 Amp DC OUTPUT
FUSE to open within 2 minutes.
3. OVERLOADING the Battery Saver in excess of 20 amperes when the BSLR
is OFF:
A. When the BSLR is OFF, loads are powered by the battery, which is
overload protected with a ATC 25 Amp fuse. The fuse will open
when the current exceeds 30 amperes for 2 minutes
Example:
A load of 25 amperes will cause the Batery Saver output to current limit with a
corresponding decrease of output terminal voltage to less than 10.0 VDC. This same
25 ampere load WILL NOT cause the ATC 25 Amp fuse to immediately open when
the load is connected to the vehicle battery via the 091-195.
Manage Battery Saver Connected Loads to 20 Amperes or
Less!
