[. . . ] FILE: IM_091-92-12_Rev_B DATE: 09-15-04 INSTRUCTION MANUAL BATTERY SAVER LOW RIPPLE POWER SUPPLY / AUTOMATIC LOAD SWITCH FOR 12VDC VEHICLE SYSTEMS MODEL #091-92-12 INPUT: 115 VOLTS, 50/60 Hz AC, 1. 8 amps. RMS OUTPUT: 13. 2VDC, 10 AMPS DC, 130VA 3 YEAR WARRANTY KUSSMAUL ELECTRONICS CO. , INC. 170 CHERRY AVE. , WEST SAYVILLE, N. Y. [. . . ] Be certain that adequate ventilation is available and that the unit is not subject to weather damage. Connect the 115VAC input power to the BATTERY SAVER through a 3-wire line cord as shown in INSTALLATION WIRING DIAGRAM, Figure 1. The low voltage connections are made through the DC output connector as shown in INSTALLATION WIRING DIAGRAM, FIGURE 1. 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 power supply when the AC power is ON. TEST and OPERATION The 091-92-12 Battery Saver system interface panel contains two (2) Green LEDs as follows: Refer INSTALLATION WIRING DIAGRAM, Figure 1. "LOAD POWER" LED: Illuminates when power is being supplied to the load(s) regardless of the source of the power (Vehicle Battery or Battery Saver). "BATT SVR PWR" LED: Illuminates when Battery Saver is receiving AC power and the power supply internal to the Battery Saver is ON and functioning. Installation Test 1. Verify "LOAD POWER" LED is illuminated and loads are being powered by vehicle battery (voltage at load is approximately equal to vehicle battery terminal voltage). Apply AC power to 091-92-12 Battery Saver and verify: 1. "LOAD POWER" LED remains illuminated 2. "BATT SVR PWR" LED illuminates approximately five (5) seconds after application of AC power to Battery Saver. Load voltage is between 13. 2VDC and 13. 4VDC Operation The 091-92-12 Battery Saver contains special circuitry that eliminates power delivery "glitches" or interruptions during load power transfer(s) from: *Vehicle Battery to Battery Saver: Five (5) second delay as Battery Saver power supply stabilizes. *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 (. 150 seconds). INSTALLATION PRECAUTIONS Refer Figure1, INSTALLATION WIRING DIAGRAM and Specifications & Outline The 091-92-12 Battery Saver is AC Input AND DC Output over-current protected as follows: 115VAC 60Hz Input: 5 Ampere DC Output: ATC, 10 Ampere The ATC 10 Ampere DC OUTPUT FUSE internal to the Battery Saver is common to both the Battery Saver Power Supply output AND the vehicle battery connection that supplies power to the load when the Battery Saver is OFF (115VAC to Battery Saver - OFF). Current OVERLOADING the Battery Saver in excess of 10 Amperes will: Initiate current limiting of the Battery Saver Power Supply with a corresponding reduction of the Battery Saver Power Supply terminal voltage when the Battery Saver is ON until the DC OUTPUT FUSE open circuits.
