SMPS BATTERY CHARGER – GENERAL APPLICATION
SMPS based battery chargers are built using switch mode rectifier and are used in telecom, railways emergency lighting, alarm systems and power sector. These are compact in design and are expendable to enhance the capacity. Wide adjustable output range make them suitable for all type of batteries including Lead acid (VRLA and LM), AND NI-Cd types.
The basic design of chargers and its standard modules are type tested by Indian Railway (RDSO).

  • High efficiency and low input current harmonic distortion
  • Input Supply both in single Phase and 3 Phase AC.
  • Wide input voltage range.
  • 24V – 150V /25 Amp to 800 Amp. DC systems.
  • High power factor.
  • Houses upto 8 modules per rack (Multiple racks can be connected in parallel to enhance capacity).
  • No derating up to 55°C.
  • 4X16 display for easy navigation in user menu.
  • RS232 communication / SNMP protocol /Ethernet-NMS
  • 4 potential free contacts for AC FAIL, DC LOW, DC HIGH and FR-FC FAIL
  • Lightning and surge protection
  • Reverse battery protection (optional) input.
  • AC output of range cut-off
  • Battery Under Voltage Isolation.
  • 110V DC/20A and 48V/25A module based systems type tested by RDSO
  • Customisation as per requirement
