OBSOLETE 06/2017 - The 520CS and 520CP are fully-programmable, microcontroller-based, current-sensing devices designed to monitor 3-phase pumps. The 520CP is designed to work with motors that have ramp-up times of 4 seconds or less. The 520CS has a programmable motor acceleration time that can be set from 0-50 seconds.
Both current monitors protect 3-phase motors from:
- Overcurrent
- Undercurrent
- Current Unbalance
- Rapid Cycling
- Single Phasing
- Phase Reversal
