The Unipower HPL130A.400 offers real-time load supervision using true power (kW) plus dynamic monitoring via dP/dt (rate of change of power). Designed for machines with fluctuating loads, it supports auto-reset, peak detection, and 4-20mA output proportional to load. Voltage change compensation via dU/dt ensures robust alarm handling.
🔧 Technical Highlights:
- Measuring Voltage: 3 x 400V AC
- Power Calculation: P = √3 x U x I x Cosϕ
- dP/dt and dU/dt Monitoring: For detecting sudden load change
- Output: Relay + 4-20mA current loop
- Current Input: 1, 3, 5, or 8A internal / External CT
✅ Benefits:
- Monitors shock loads and slow overloads
- Protects motors from blockages and jams
- Compensates for voltage variations
🚀 Applications:
- Screw conveyors and bucket elevators
- Mixers and crushers
- Machinery with frequent load shifts
Combines power monitoring with dynamic profiling for early fault detection.
