The Unipower HPL503 is a dedicated kW/kWh transducer delivering analogue and pulse outputs for use in energy management systems. It supports internal current up to 40A and external CT scaling, with full setup via front panel.
🔧 Technical Highlights:
- Voltage: 100-575V AC (1- or 3-phase)
- Current: 0.5-40A internal or 50-1000A external CT
- Outputs: 0(4)-20mA analogue + kWh pulse output
- kWh Pulse Rate: 0.1, 1.0, or 10 kWh per pulse
- Display: kW, kWh, % of scale
✅ Benefits:
- kW readout with process-scaled analogue signal
- Pulse signal for data loggers and PLCs
- Ideal for submetering or energy audits
🚀 Applications:
- Power monitoring panels
- SCADA and data logging systems
- Load tracking in commercial plants
Multifunction transducer combining real power and consumption output in one device.
FAQs
- Q: What is the difference between the kW and kWh outputs on HPL503?
A: The analogue output represents instantaneous kW, while the pulse output represents accumulated kWh energy over time.
- Q: Can I log motor energy usage with HPL503?
A: Yes. By counting the kWh pulses from HPL503 you can log energy consumption for individual motors or groups of loads.
- Q: Does HPL503 replace a standard energy meter?
A: It can provide similar information as an energy meter for selected circuits, particularly where you need both a kW signal and a kWh pulse output.
