Voltage Monitor is a device that displays the measurement of the voltage and frequency of power supply by using different color LEDs.
Description Front
Indication of the value of power
frequency:
LED from 1 to 3
LED 1 color yellow
LED color green
LED 3 color red
Indication of the value of the supply
voltage:
LED from 4 to 6
LED 4 color yellow
LED 5 color green
LED 6 color red
Mechanical dimensions: 36 x 7 mm; 50 mm depth.
Container for electronic products according to DIN 43700 in self-extinguishing
material in black color.
Links Operation
Connect the Voltage Monitor to the power supply that you want to
measure.
For every time the instrument is tested to verify proper operation of all
LEDs.
Once the test on the LEDs, the device starts its operation.
Indication of the voltage:
Depending on the value of the supply voltage detected, the LEDs 4-6, as shown in
the table opposite.
Voltage value LED:
To 2 0 V
From 2 to 220 V
From 22 to 235 V
From 236 to 245 V
From 246 V forward
= led on
Indication of the frequency value:
Depending on the value of power frequency detected, the LEDs 1 to 3, as shown in the tables below. Voltage Monitor can work in two different
ranges of values of frequency around 50 Hz and about 60 Hz The device automatically sets the range at power up.
If the device is
initially powered
with a frequency
lower than 55 Hz,
the display
indications have
the values shown in
the table opposite.
Indication of the value of frequency,
range of values around 50 Hz
Frequency values LED:
To 48 Hz
From 48,5 to 50,5 Hz
From 50,8 to 5 ,8 Hz
From 52 Hz forward
= led on
If the device is
initially powered at
a frequency of 55
Hz, and the
frequency ranges
have the values
shown in the table
opposite.
Indication of the value of frequency,
range of values around 60 Hz
Frequency values LED:
To 58 Hz
From 58,5 to 60,5 Hz
From 60,8 to 6 ,8 Hz
From 62 Hz forward
= led on
Operating Specifications

Maximum operating voltage 60 V
Accuracy of measurement 5%
Minimum frequency of operation 40 Hz
Maximum frequency of operation 70 Hz
Accuracy of measurement 5%
