PTS TYPE
VOLTAGE RELAY
PTS TYPE
High-performance under-voltage relay
that activates output when all 3-phase voltages
fall below a reference voltage by monitoring voltage
on each phase of 4 wires
FEATURES
Monitoring voltages of 3-phase 4 wires with a single unit
The PTS type for monitoring 3-phase 4 wires is newly available in addition to
the conventional FVS type that monitors only one phase. The PTS type
under-voltage relay monitors all 3-phase voltages to verify that voltages on all
phases are lower than a reference voltage. The PTS type incorporates 1a1b
output contacts.
Operation status LED
Digital switch
With the operation monitor LED, you can
easily check control power ON/OFF
status and monitor voltage.
(POWER, UV)
The digital switch simplifies the reference
voltage setting procedure.
G17
Labels that indicate reference voltage settings
are included in the product.
If you attach a label after setting a voltage, you
can easily confirm the reference voltage.
Since control voltage is input from the monitor power
supply, the relay unit does not need an additional
control power supply.
∗ The internal relay turns OFF when input voltage
falls below 38V regardless of the reference voltage
setting.
High-performance engineering
plastic is used for the storing case.

●Operation
By monitoring input voltage on each phase of AC 3-phase 4 wires, the output contact is switched when all
3-phase voltages fall below a reference voltage. The internal relay has no voltage when input voltage is
38V or lower regardless of the reference voltage setting.
The above operation chart is based on “a-contact” output.
In constant monitoring mode, the internal relay is ON.
⇒ (Terminals 3 - 4: Open, Terminals 5 - 6: Closed)
When all 3-phase voltages fall below a reference voltage or when the monitor input is lost, the internal
relay turns OFF.

Reference voltage (operating voltage) setting
By referring to the “Digital switch selection table” on
the side of the relay unit, specify a reference voltage
with the digital switch.
(Example: To set “70 V AC”, turn ON the No. 4 bit.)

■Instructions for handling the product and other information
● When setting a voltage, be sure to disconnect the
relay unit from the socket, or do not apply a monitor
voltage or power supply voltage to the relay unit (to
prevent output error).
● After setting a voltage, be sure to attach the voltage
indication label suitable for each state (to prevent
erroneous operation and entry of a foreign
substance).
● When you set a reference voltage with the digital
switch, do not turn ON multiple bits simultaneously
(to prevent output error).

DEVICES
● This product is applicable to a 3-phase 4-wire voltage
circuit and is not applicable to a 3-phase 3-wire
voltage circuit. In applications to other circuits, this
product enables monitoring of typical phase voltage
of 3-phase 4-wire circuit, and monitoring of
single-phase 2-wire voltage.
● For connection with a PT (transformer), check the
capacity of the transformer (including other load).
