Unipower HPL110
Generally
Low cost kW-meter with built-in functions
for control and supervision of AC-motor
driven equipment. A very popular and
inexpensive unit. The more advanced
functions implemented in our HPL400
family are not present in this unit. The unit
is used by several manufacturers of pumps,
conveyors and special machinery. Some of
these have their own logo on the front plate.
This is also an option for future customers.
Features
* kW[%] measurement
* Digital programming
* Start timer 0,1-99.9 sek
* Reaction timer 20ms-99.9 sek
* Max. limit 5-100%
* Min. limit 5-100%
* 2-points regulation
* Built-inPeak detector
Applications
* Pump supervision (Max. and Min.).
* Supervision of conveyor belts.
* Simple overload supervision of
cranes.
* 2-points regulation via hysteresis on
the Max.- or the Min.-limit.
* Other machinery where an alarm is
required on a given motor torque
(Max. and Min.).

Unipower product program
Units for DIN-rail mounting (35mm) or panel mounting
(72 x 72).
Measurement transducers: 1- and 3-phased kW-
measurement. Symmetric and asymmetric. Before and
after frequency inverters. Analogue output (4-20mA)
as well as pulse output (kWh).
Load monitors: 3-phased symmetric kW-measure-
ment. Programmable kw-limits: Max., Min and dP/dt.
Support functions: Start timer, reaction timer, hyste-
resis, auto reset, manual reset, alarm blocking etc.
Analogue output (4-20mA).
Tool supervision: Kompact units for supervision of
up to 16 cut. Measurement of power and work for
break, wear and missing tool. Monitoring program for
installation and statistics, for DOS or Windows.
Typical wiring
The Figure above shows a typical AC-motor power
consumption curve immediately after power has been
applied to the motor. The bars at the bottom of the figure
indicate power applied to the unit and the position/state
of the relay (On/Off). The figure shows the functions
and the parameters of the HPL110 in two different
situations; hysteresis on the Max. limit and hysteresis on
the Min. limit. Note that the use of hysteresis on the Min.
limit requires the Max. limit to be Off.
