II. PRECAUTIONS
1. The Battery Saver Low Ripple HO is AC Input
AND DC Output over-current protected as follows:
A. 120VAC 60Hz Input Fuse: 6.3 Amp
B. 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 correspond-
ing 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
an 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 bat-
tery via the BSLR.
Manage Battery Saver Connected Loads to 20 Amperes or Less!
TEST AND OPERATION
I. ELECTRICAL TEST
1. Remove AC power from the BSLR.
2. Verify “
BAT SVR ON” LED is OFFand loads are being powered by vehicle battery (voltage at load
is approximately equal to vehicle battery terminal voltage).
3. Apply AC power to BSLR and verify:
A. “
BAT CONNECTED” remains illuminated.
B. “
BAT SVR ON” LED illuminates approximately five (5) seconds after application of AC power
to Battery Saver.
C. Load voltage is between 13.2 VDC and 14.0 VDC.
II. OPERATION
The Battery Saver Low Ripple eliminates power delivery “glitches” or interruptions during load power
transfer(s) from: Vehicle Battery to Battery Saver: Five (5) second delay as Battery Saver output sta-
bilizes. Installation Test para. 3.2. Battery Saver to Vehicle Battery: No delay. The MINIMUM voltage
at the load during any power transition is: Vehicle Battery VDC - 1.3VDC for a MAXIMUM of 150
milli-seconds (0.150 seconds).
