Motor Load Monitor, True kW, 0/4-20 mA Output, Dual Relays is a digital load monitor designed for protecting pumps, conveyors and other motor-driven machines by measuring true motor power. Its wide single- and three-phase voltage coverage, internal current ranges up to 40 A and isolated analogue output make it suitable for both protection and load feedback duties.
🔧 Technical Highlights:
- Measures true motor power on 1 x 100-400 V AC and 3 x 100-575 V AC systems
- Internal current ranges from 0.5 A to 40 A with external CT option up to 600 A
- Isolated analogue output configurable as 0-20 mA or 4-20 mA
- Dual relay outputs for high and low load limits
- DIN rail or wall mounting in a compact housing
✅ Benefits:
- Helps detect overload, underload and dry-run conditions using real power measurement
- Provides analogue load feedback for monitoring and control
- Reduces the need for separate transducers and protection devices
- Covers a wide range of voltages and currents with one unit
🚀 Applications:
- Pump dry-run and overload protection
- Conveyor jam and loss-of-load monitoring
- Mixer, crusher and hoist supervision
- Motor-driven machinery requiring load feedback and alarms
Designed for dependable kW-based machine protection where accurate load monitoring and clear alarm output are required.
FAQs
- Q: Why use true kW measurement instead of current alone?
A: True power monitoring gives a more reliable picture of motor load, which is useful for detecting both overload and low-load conditions such as dry run or broken belts. - Q: Can this unit provide both alarms and analogue feedback?
A: Yes. It includes dual relays for load limits and an isolated 0-20 mA or 4-20 mA output for proportional load indication.
