  • Page 8 Testing 17. Testing Perform all tests as shown below, before the first use of the unit. It allows you to check every function of your charger kit. Use the supplied 5W dummy load resistors and a reliable multimeter. -1- Put SW2 in the 12V position. Measure the voltage across the output terminals.
  • Page 9 Testing -3- Put SW2 in the 12V position, put SW1 in the >4Ah position. Connect the supplied 33Ω/5Ω resistor to the output terminals. Measure the voltage across the resistor. It should read 14.7V +/- 0.1V Fig. 3.0 -4- Put SW2 in the 6V position, put SW1 in the >4Ah position. Connect the supplied 33Ω/5Ω...
  • Page 10 Testing -5- Put SW2 in the 12V position, put SW1 in the >4Ah position. Connect the supplied 8.2Ω resistor in series with the multimeter. Switch the multimeter to the ‘10A DC’ - position. It should read 1A +/- 0.1A. Fig. 5.0 -6- Put SW2 in the 12V position, put SW1 in the <4Ah position.

  • Page 14 Connection & Use 19. Connection & Use Connection: The unit can be connected as shown on figure 10. Fig. 10 Make sure your assembly complies with the local safety regulations. For improved safety, use a non-conductive enclosure.
  • Page 15 Connection & use Use: perform the necessary settings before you hook-up the battery to the unit : Select the appropriate charge current and voltage according to the capacity of the battery. Batteries < 4Ah: 0.3A charge current Batteries > 4Ah: 1A charge current You can easily estimate the charging time with the following formula : Approx.
  • Page 16 Operation & troubleshooting 20. Operation & troubleshooting Operation: When a discharged battery is connected to the unit, it starts charging it with the maximum current (0.3A for batteries <4Ah, 1A for batteries >4Ah), until the battery voltage reaches 14.7V (7.35V for a 6V battery). Once this voltage is established, the charger adjusts the charge current, in order to keep this voltage steady.
