MOTOR & SUPPLY POWER MONITORING MODULE TYPE ABS CA 443

For all your electrical measuring needs

The CA 443 is an electrical property measuring device used either for a complete station or for a single pump. It can be connected to the PC 441 via a galvanic-isolated CAN-bus interface and can only be used in combination with the PC 441 monitoring/controller unit.

Description

Main design features
  • The CA 443 is connected to all three phases, voltage, and current
  • The direct connected monitoring range is 300 VAC (phase-neutral), 520 VAC (phase-phase) and via standard current transformers with a secondary current of 0 – 5 A. A separate voltage transformer is required to connect a higher voltage
  • A phase angle correction can be set in the PC 441 software for external voltage transformers
  • Thanks to its galvanic isolated CAN-bus interface, you can mount the monitoring device either in the cabinet or up to 250 meters away from the pump

Key characteristics

  • Voltage monitoring in all phases
  • Current monitoring in all phases
  • Power factor calculation
  • Energy consumption calculation
  • Alarm for high/low supply voltage
  • Alarm for high/low power supply frequency
  • Alarm for phase failure and unbalance
  • DIN rail mounted
