The Unipower HPL530 is a shock load monitor that supervises sudden load changes using a 160ms sliding window analysis of power change (dP/dt). It supports voltage compensation (dU/dt) and provides advanced filtering and scaling for analogue and relay outputs.

🔧 Technical Highlights:

  • Voltage Range: 100-575V AC (1- or 3-phase)
  • Current Range: 0.5-40A internal or 50-600A external
  • Special Function: Shock load supervision via dP/dt
  • Outputs: Dual relays, 4-20mA, kW/P2 selectable
  • Filter: Damping filter with 250ms response time

✅ Benefits:

  • Detects load spikes and fast overloads
  • Corrects false alarms with voltage compensation
  • Provides shaft power monitoring

🚀 Applications:

  • Dynamic loads (e.g. crushers, feeders)
  • High-variability material handling
  • Critical plant protection

Smart protection unit for machines subject to fluctuating mechanical stress.
