1. General Description
Mikro®’s power factor regulator X80 is designed to detect and
compensate displacement power factor caused by inductive load by
switching in banks of capacitors. As oppose to traditional regulator
that only measures reactive power on a single phase basis but
compensates three phases, the X80’s Three Phase model is a true three
phase system as reactive power of all three phases are measured
individually and compensated optimally.
Mikro®’s power factor regulator X80 also provides exibility in conguring (or disabling) dierent levels of alarms. The alarms can then be
linked to dedicated signal contact to alert the users of potential issues
such as under compensation (thus avoiding penalty charges from the
utilities).
Mikro®’s power factor regulator X80 provides the user with a 2 inch
wide, 64 x 128 dot matrix LCD for displaying its various measurement
parameters such as: frequency, voltage, current, THD, active, reactive
and apparent power and temperature. The dot matrix LCD allows up to
31st order voltage and current harmonics to display in graphical and
table form.

4. Installation Guide
Before installing the X80, please ensure that the environment
meets the following conditions:
- Operating temperature: -5°C to +55°C
- Humidity: 56 days at 93%, 40°C non-condensing
- Dust free environment away from electrical noise and radiation.
5. Mounting
Insert the X80 through a 138mm x 138mm switch-gear panel as
shown below:
138mm
EXIT : To exit from menus, submenus or to cancel setting value
change. For X80 three phase models, at the main display page,
pressing EXIT will scroll through the display page for Phase 1,
Phase 2 and Phase 3 parameters
UP : Scroll up the menus or increase settings value.
Down : Scroll down the menus or decrease settings value.
Enter : To enter submenus or to conrm settings value change.
As per Mikro®’s power factor regulator series, it includes the automatic
C/K and rated step size detection feature for ease of commissioning for
typical inductive loads. Taking advantage of the dot matrix LCD, the
X80 also provides a guided step-by-step commissioning menu that
enables fast setup.
The regulator extends its connectivity by adopting the Modbus-RTU
protocol. Through the use of RS485 standard protocol, the user will be
able to network the regultor with other IEDS that linkto a center
monitoring station.
2. Precautions
Please read the instructions carefully before operating the
a) Before powering up X80, make sure auxiliary voltage supply does
not exceed the range given in connection diagram (i.e. 85 - 265 VAC or 110
- 370 VDC).
b) Ensure that there is no high voltage injected into terminal 13, 14, 23,
24 36, 37, 38, 39, 40, 41, 42 and 43.
c) If LCD display and AUX LED does not turn On after powering up X80,
please stop using the X80 and contact the manufacturer for service.
d) If any crack is found on the casing, please stop using the X80 and
contact the manufacturer.
