Samlexpower SCC-1208L Manuel Du Propriétaire page 5

SECTION 2 |
• 3 Stages of charging for 100% return of capacity and long battery life – Bulk, Absorp-
tion and Float Stages
• Can safely charge 2 types of Lead Acid batteries – Flooded / Wet Cell (Absorption Volt-
age 14.8V) or Sealed AGM (Absorption Voltage 14.5V)
• Very low self consumption of < 9 mA
• MOSFET based reverse current blocking for night-time battery discharge prevention.
This allows much lower losses as compared to Diode based blocking
• Totally sealed and splash proof design with Ingress Protection Rating of IP65. Can be
installed in outdoor locations
• Wide operating temperature range of -40°C to +60°C
• Automatically turns on the loads (like lights) when dark and turns off at day time.
Ideal for street lights / automatic night lighting
• Low voltage disconnect protects the battery against deep discharge when the load is
connected to the Load Terminals.
• Protected against overload, over temperature, under / over voltage on the battery side
and reverse polarity (see Specifications)
• EMC compliance to FCC Standard Part 15(B) for Class B Devices and European Standard
EN61000
• Industry leading warranty of 5 years.
2.3 PWM BATTERY CHARGING ALGORITHM USED IN SCC-1208L
Please read Section 3 for supplementary information on PWM charging control.
Fig. 2.1 represents the 3 stages of charging used in SCC-1208L. The charging is carried out
in 3 stages:
