Nothing is smarter than SMART
Smart MPD · PLF · Color LCD · Combined Control
The next-generation flagship power regulator integrating all of Paraent's power regulator technologies
The Max Power Distribution Control function smooths main power by distributing power among multiple power regulators when controlled with zero-crossing. Improves power factor and reduces peak power.
When multiple parallel loads are connected to a single power regulator, this function detects partial load open circuits. Auto-tuning acquires load characteristic patterns for accurate detection.
Improved user interface with color LCD and 18-key pad. Enables self-diagnostics, test mode, easy parameter settings. Can be attached to the unit or mounted separately on a panel.
Saves cost and space by mounting up to 3 single-phase power regulators in one body. Supports various wiring methods: 1P1L, 1P2L, 1P3L, 2P2L, 3P2L, 3P3L, 3P4L, 3P6L.
1) Power Factor Improvement
- Max Power Distribution Control smooths main power by distributing power among multiple power regulators when controlled via zero-crossing.
- The waveform difference between standard zero-crossing and power distribution control is shown below.
(Patent No. 10-1405243: Power regulator with partial load failure detector and detection method)
- Detects partial load open-circuits when multiple parallel loads are connected to a single power regulator.
- Auto-tuning acquires load characteristic patterns to achieve accurate partial load failure detection.
- Improved user interface with color LCD and 18-key pad.
- Self-diagnostics, test mode, and easy parameter settings for improved user convenience.
- PSD can be attached to the unit or mounted separately on the front panel for better visibility.
- Displays voltage / current / power / resistance (temperature: optional) and cycles through parameters for each phase.
- Graphically displays input and output values for enhanced real-time visibility.
- The display unit is detachable; when mounted on the panel front, there is no need to install separate ammeters or voltmeters.
- Up to 3 single-phase power regulators in one body, each controlled by its own input signal. Compatible with all heater wiring configurations.
- Each alarm can be routed to one of 3 relays per user selection.
- User selects whether output is cut off when an alarm triggers.
- Fan speed driven by heatsink temperature as specified by user to extend fan life.
- Warning and alarm thresholds for heatsink overheat set at user-defined temperatures.
- Alarm types:
① Over-current ② Fuse open ③ Heater open ④ Heatsink overheat ⑤ SCR element fault ⑥ Load imbalance ⑦ Main power cutoff ⑧ FAN fault ⑨ Frequency noise ⑩ PLF (Partial Load Failure)
