A77 Series
SCR Battery Charger / Battery Eliminator
Microprocessor Controlled SCR Battery Charger
The La Marche Model A77 Series Battery Charger is engineered for the demanding requirements of Switchgear, Process Control, Oil Exploration and other DC power applications.Powered by Microprocessor Controlled SCR technology, the A77 Series Battery Charger / Battery Eliminator has ±0.25% DC voltage regulation from no load to full load over the specified input voltage, frequency and ambient temperature ranges.These chargers are available in DC output voltages of 24, 48, 130, and 260 VDC with DC output currents from 6 amps and above. Consult factory for any special input and output requirements not mentioned above.The La Marche A77 charger provides value added features such as AC/DC breakers, easy to read LCD display with text readout alarm LED’s and form “C” alarm contacts. Communication options are available to remotely monitor and control the charger using DNP3, Modbus, IEC 61850 and SNMP protocols.
