    1. General ARG Series Battery Charger with Battery Group is specifically designed to be used in power stations and substations. The device combines battery charger and battery group in one cabinet; provides a compact solution for space constraint facilities. SCR based battery charger rectifies AC voltage and to supply DC supplied components and keep batteries charged.

    2. Functions Simplified block schema of ARG Series Battery Charger with Battery Group is given at the below. ‘*’ marked functions are optional. 2.1. Rectification Microcontroller controlled 2-thyristor / 2-diode full bridge rectifier circuit and input isolation transformer is used for rectification. DC load and battery charging is controlled separately.

  • Page 6: Metering

    Default limits (0.1C and 0.3C) are determined for VRLA batteries. Refer to battery datasheet to verify maximum charge current limits. 2.3. Metering The device control unit measures following parameters • AC input voltage, • DC output voltage, • In-cabinet temperature. •...

  • Page 7: Deep Discharge Protection

    battery group doesn’t able to get charge or provide power. • If charger to battery group connection is faulty, broken cable or not properly connected multi-contact plug socket with models with drawers. 2.5.4. Deep Discharge Protection If AC input is not present and battery group voltage drops to preset deep discharge voltage level, this module disconnects battery group from load to prevent unrecoverable deep discharge state.

  • Page 8: Surge Protective Devices

    2.8. Surge Protective Devices Surge protective devices (SPD) are used as transient suppressers at AC input. SPDs will be installed before isolation transformer between L-PE and N-PE. This module is optional. Lightning protection shall be coordinated to make it effective; used SPDs are Class III according to IEC 61643-1 and not effective alone to protect devices in facility.
  • Page 9 The device has two cable entries, one on the side and one at the bottom of cabinet.  Side entry which is next to MCBs and alarm module is easier to access.  If bottom entry is preferred: o In models with drawers, there are no obstacles between terminals and entry or use cable spiral wrap as guide.
