Charger For Standart Profesional (Pro901S-Pro906S)

3. a) Charger Sub-System (Pro901S & Pro902S)   

   The purpose of charger is to charge and to maintain the batteries at fully charged     

   condition. Refer to figure 7, the voltage flyback switching power supply provides a 

   constant DC voltage (27.4 Vdc) for batteries. Besides providing constant voltage, the 

   power supply also limits the current flowing into batteries and therefore protects and 

   prolongs the life time of charged batteries.

b) Charger Sub-System for Pro903S 

   The purpose of charger is to charge and to maintain the batteries at fully charged 

   condition. Refer to figure 4, the voltage fly-back switching power supply provides 

   a constant DC voltage (83.8 Vdc) for batteries. Besides providing constant voltage, the 

   power supply also limits the current flowing into batteries and therefore protects and 

   prolongs the life time of charged batteries.
