INTRODUCTION
The Battery Saver Low Ripple (BSLR) is a power supply with a load power transfer function. Loads
connected to the BSLR are powered by the vehicle’s battery when the AC power to the BSLR is OFF.
When AC power is applied to the BSLR special circuitry within the Battery Saver transfers the load(s) to
the Battery Saver output. The Battery Saver output then provides low ripple 12VDC System power to
Battery Saver load(s). Installation of a Battery Saver eliminates the power drain on a vehicle battery and
or a battery under-charge ensuring all vehicle battery charger power is available to charge the battery.
This Battery Saver is unique in that there is no interruption of power supplied to the loads during power
transfers. The feature makes the BSLR ideal for Mobile Data Terminal (MDT) and or 12VDC vehicle
computer systems that may “re-boot” during an input power interruption.
FEATURES
I. BATTERY SAVER LOW RIPPLE
• Clean, low ripple output causes no interference with sensitive electronics
• Relay removes auxiliary loads from vehicle battery and connects to battery saver, preventing
battery discharge when in station
• Fast acting relay ensures “glitch” free power transfer
• Current limiting prevents overload
• Power “ON” LED status indicator
• Pump output with AC or DC mode rocker switch
II. LED STATUS INDICATORS
1. BATTERY CONNECTED: Indicates that a battery of proper polarity is connected to the charger
output terminals
2. BATTERY SAVER ON LED: Indicates that Battery Saver is receiving AC power and the power
supply internal to the Battery Saver is ON.
INSTALLATION INSTRUCTIONS
I. WIRING AND MOUNTING THE BATTERY SAVER LOW RIPPLE HO
1. Mount the Battery Saver in a convenient location with 4 screws in the mounting holes provided.
Be certain that adequate ventilation is available and the unit is not subject to weather damage.
2. Connect the 120VAC input power to the Battery Saver using the suppled IEC line cord as shown
in INSTALLATION WIRING DIAGRAM, See Figure 1.
3. The low voltage connections are made through the DC output connector as shown in INSTAL-
LATION WIRING DIAGRAM, See Figure 1.
4. Connect terminal 1 to the vehicle’s 12 volt battery (+).
5. Connect terminal 2 to the vehicle ground or to the battery (-).
6. Connect terminal 3 to the +12 volt electrical loads.
7. The installation is now complete. Loads connected to the Battery Saver will be powered from
the vehicle battery when the AC power to the Battery Saver is OFF and from the Battery Saver
output when the AC power is ON.
