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.
FAQs
- Q: What does HPL530 detect that a normal load monitor might miss?
A: HPL530 focuses on the rate of change of power (dP/dt) to detect very rapid load increases associated with jams and shock loads.
- Q: Is HPL530 suitable for continuous over/underload protection?
A: It is primarily intended for shock load and jam detection. For continuous over/underload protection you would typically combine it with a standard load monitor.
- Q: Where is HPL530 most often used?
A: On heavy conveyors, crushers and similar equipment where sudden mechanical jamming can cause serious damage.
