POWER LIMITER PMM-02
DESCRIPTION
The PMM-02 power limiter auto-
matically isolates supply voltage from the
controlled power loads when they over-
load the set power threshold. The power
threshold can be set smoothly from 0.1
to 3 kW with a potentiometer. The power
threshold trip-on delay of the relay can be
set smoothly from 10 to 90 s.
FEATURES
● Overload protection with a power
threshold setting.
● Electrical system overcurrent protec-
tion.
● Power supply indicator.
● Power overload indicator.
● Stepless trip-off delay setting.
● Wide power load control range.
● Resilient to transient power loads
above the set power threshold.
● Single-module enclosure.
● For installation on a DIN rail.
The device is designed for a
single-phase installation and
must be installed in accord-
ance with standards valid in a
CAUTION
particular country. Installation,
connection and control should be carried
out by a qualified electrician staff, who act
in accordance with the instruction manual
and the device functions. In case of cas-
ing dismantling, the guarantee is lost and
an electric shock may occur. Before instal-
lation make sure the connection cables
are not under voltage. The cruciform head
screwdriver 3,5 mm should be used to in-
stall the device. Improper transport, stor-
age, and use of the device influence its
wrong functioning. It is not advisable to in-
stall the device in the following cases: if any
device part is missing or the device is dam-
aged or deformed. In case of improper func-
tioning of the device contact the producer.
Do not dispose of this device with
other waste! In order to avoid
harmful effects on the environment
and human health, the used device
should be stored in designated
areas. For this purpose, you can
dispose of household waste free
of charge and in any quantity to
a collection point set up, as well
as to the shop when you buy new
