  • Standalone – benchtop or fixed mounting
  • Front panel controls & indication
  • Suitable for float charging of lead-acid batteries
  • Suitable for parallel operation
  • Conservative design for long life
  • Precise voltage and current control

Optional Features

  • American Input Voltage 110VAC ( 88 – 135VAC)
  • Communication Port ( RS232 ASCII – SR485 – MODBUS RTU  – SNMP , webpages)
  • Mounting:  Rack Mount 19″ with V/I meter available, Wall mount
  • N+1 redundancy
  • Boost Charger
  • Optional temperature compensation for charging
  • Optional relay alarm outputs
  • Optional DC input

Applications

  • Security – Access Control
  • Industrial Processes Switching Protection
  • SCADA
  • Radio Repeaters – Remote Sites

Accessories Supplied

  • Mounting feet together with screws
  • AC power cord 1.5m with IEC320 socket and NZ/Aust plug
