Explosion Proof Battery Charger From APS

APS APS BC-6964 battery charger

 January 28, 2020

Applied Power System explosion proof BC-6964 battery charger

The BC-6964 Battery Charger from Applied Power Systems is designed for hazardous operating environments that require explosion proof Class I Div I and Div II equipment. The charger is housed in an aluminum explosion-proof enclosure and implements an advanced charging algorithm to provide extended battery life.

In voltage mode, the BC-6964 Battery Charger regulates to a factory set DC voltage. While operating as a voltage source, the battery charger regulates its output voltage to provide optimum charging of the battery. If the output current demand exceeds a maximum setpoint, the battery charger efficiently transitions from voltage source to current limit, where the battery charger reduces the output voltage to limit the current to the maximum charge current. As the battery load decreases, the BC-6964 will seamlessly return to voltage mode.

The BC-6494 AC input voltage is EMI filtered and rectified to a high voltage of approximately 650 VDC, filtered and stored in a DC link capacitor bank. A high frequency IGBT full-bridge output inverter is pulse width modulated into the primary of a high frequency step down transformer. The transformer secondary is rectified, filtered and regulated to produce the precision battery charger output voltage.

An optional communication port is available to provide remote monitoring of the Battery Charger operation.

  • High efficiency transition from voltage mode to current mode operation
  • High frequency operation
  • Complete Fault Detection and Diagnostics
  • Safe shutdown functionality
