HPL500 Digital Motor Load Monitor

The HPL500 replaces the HPL420 and also incorporates many new features, however it has been designed so that users of the HPL420 will be familiar with its set-up procedure. The display is used as a reference enabling true motor load, trip levels and all other variables to be displayed and programmed quickly and accurately using only three push buttons. For two speed motor applications an input allows the application to select the active limit
The HPL500 is usually mounted in the motor control panel and is connected to a convenient point on the motor supply (before Inverter - if used).
Therefore no external field wiring or sensors in the equipment are necessary. In addition to displaying true motor power in real time the units capture and, on demand, display the instantaneous minimum and maximum power levels to assist in setting up trip limits and fault diagnosis. The HPL500 features a current feed-through tube for measuring continuous motor currents up to 40 amps, (27.7kW at 3 x 400vac). Therefore no Current Transformer is required unless the motors continuous current exceeds 40A.
A specially designed power supply (Patent Pending) allows the motor voltage to be programmable from 100 – 400vac single phase and 100 – 575vac 3-phase making the HPL500 suitable for world-wide use.
The 0(4)-20ma analogue output, which is proportional to motor load, can be scaled to the range of measured power and can be inverted for use in closed loop control systems.

Measures true motor load in kW (√3 x I x V x Cosφ) and futures a digital display of kW% and kW, and programmable trips for over and/or under load events
Can be programmed to calculate Shaft Output Power P2 if required
Protects equipment from damage caused by the motor running against a jam, blockage or under load
Used in processes to trigger actions when predetermined load levels are reached (end point monitoring)
Three digital delay timers, programmable from 0.1-99.9 seconds are incorporated to time out motor start surge and short duration over and under power events which could cause nuisance tripping
Two output relays are individually programmable, over or under-load alarms
Output relay state (NO or NC) can also be programmed
All settings are key-lock protected
Used for the over/under load protection of: Pumps (dry run, closed valve), Fans (broken belt, closed damper), Conveyors (screw and belt) Separation screens, Macerators, Scrapers, Mechanical drives (gearboxes, chains)
Also suitable for Process Control, PLC and SCADA input
