Added time of alarm up to 999 hours. Displays the
time, alarms have been active (while supply voltage
applied only)
LEDs for alarms, allocation of values and states of
relays
2 output-relays, each for monitoring frequency and/
or voltage
function of relays (nc- or no -operating mode) pro-
grammable
interlocked switching or autoreset
input for Enable / Reset
easy programming by help of basic programs
Sealing of settings is possible
code-lock against manipulation of settings
universal power-supply AC/DC 24-270 V
housing for DIN-rail-mount, 70 mm wide, mounting
height 66 mm
Voltage Monitoring Type UFR
Voltage- and Frequency Relay UFR1001
with integrated vector shift relay, sealable
The voltage- and frequency relay
UFR1001 monitors voltage and
frequency in two- or three-phase
networks with or without neutral
and switches o rapidly when
required.
The device can be easily adapted
to the requirements of the carrier
of the power network.
With the integrated vector-step
relay it can also monitor networks
at synchronous generators.
After selecting a basic program,
for each relay limits can be
programmed for over-/undervol-
tage and over-/underfrequency.
In programs with vector-step-
monitoring, K2 is used for vector-
step only.
Applications are monitoring
power-networks at great solar-
plants, in block power heating
stations, also with synchronous
generators (vector shift) or ge-
nerally monitoring the quality in
power networks at machines or
power-supplies.
