Unipower 8A HPL Motor Load Monitor, Motor Condition Monitoring Device, 380V, 440V, -15°C to 50°C HPL110.380-440

Unipower HPL110.380-440 is an 8A Motor Load Monitor designed as a Motor Condition Monitoring Device operating with supply voltages of 380V and 440V. It functions effectively in temperature ranges from -15°C to 50°C and provides robust motor protection by accurately measuring true motor load in kilowatts with a clear digital display of load percentage and power.

This digital motor load monitor features programmable trips for both overload and underload events, protecting equipment from damage caused by motors running against jams, blockages, or improper loading. Its intuitive interface uses only three push buttons for quick and precise programming, making it user-friendly for industrial applications.

It incorporates three programmable digital delay timers (0.1 to 25 seconds) to mitigate nuisance tripping by timing out motor start surges and short-duration power fluctuations. A DIP switch secures all setting adjustments against tampering. This unit supports operation in either manual or auto-reset modes, with auto-reset featuring programmable hysteresis for reliable differential between trip and reset levels.

The device is typically panel-mounted on DIN rails within motor control panels, connected conveniently on the motor supply line prior to any inverter. This eliminates the need for external field wiring or auxiliary sensors, simplifying installation and maintenance.

In addition to real-time power monitoring, it stores and displays instantaneous minimum and maximum power levels on demand, facilitating troubleshooting and setup. Its IP20/IP40 ratings provide basic protection against solids and liquids typically encountered in industrial environments.

Applications include overload and underload protection for pumps (dry run, closed valve), fans (broken belt, closed damper), conveyors (screw and belt types), separation screens, macerators, scrapers, and mechanical drives such as gearboxes and chains.

Displays true motor load with digital readout in kilowatts and percentage. Programmable trips for overload and underload protection events. Three digital delay timers programmable from 0.1 to 25 seconds for surge management.

DIP switch provided for tamper-proof settings. Operates in manual or auto-reset modes with programmable hysteresis. DIN rail mounting for secure panel installation. Connects on motor supply line without external sensors or wiring.
