SECTION 5 | Battery Charging in Evolution™ Series
If the unit was in Inverting Mode [Blue LED marked “ON” (12, Fig 2.1) steady] and the Charging Prole is set to
4-Stage Adaptive Charging Prole for Equalization as above by pressing the ON/OFF Push Button for 1 second,
the unit will initiate Equalization Prole whenever qualied AC input is available. To terminate Equalization Prole
prematurely before its completion, press the ON/OFF Push Button for 1 second.
NOTE: Procedure described above is to be used when the optional Remote Control EVO-RC-PLUS has NOT been
plugged into the RJ-45 Remote Control Jack (7, Fig 2.1). Please note if the Remote Control has been plugged
into the RJ-45 Jack, the above procedure cannot be activated and the ON/OFF of Equalization Prole will
be controlled by the Remote Control EVO-RC-PLUS.
5.10 2-STAGE CHARGING PROFILES
2-Stage Charging Prole may be used for charging Lead Acid, Lithium Ion and Nickel-Zinc (Ni-Zn) types of batteries.
In 2-Stage Charging Prole, the battery is charged in Bulk Stage rst and then in Absorption Stage or Float Stage. There
is no 3rd Stage.
i
INFO
The 2nd Stage i.e. Absorption Stage may also be referred to as Float Stage in some applications like charging
Lead Acid Battery with load (battery backup application like in Telecom battery charging, Emergency
Lighting etc.). In this application, the voltage setting of the 2nd Absorption Stage is lowered to the level
corresponding to the Float Stage. Please note that under this condition, the battery will not charge fully but
only to around 80%.
The following 3 programming options are available for 2-Stage Charging:
1) Option 3 = 2 Stage Type 1: Please refer to Srl. 1 of Table 5.3 for detailed description and Fig 5.3 for Voltage
- Current (V-I) Curves
2) Option 4 = 2 Stage Type 2: Please refer to Srl. 2 of Table 5.3 for detailed description and Fig 5.4 for Voltage
– Current (V-I) Curves
3) Option 5 = 2 Stage Type 3: Please refer to Srl. 3 of Table 5.3 for detailed description and Fig 5.5 for Voltage
– Current (V-I) Curves
