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-**

* Min. limit 5-**

* 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.
