Example 3
A shunt is a resistor to convert a DC current into a DC voltage. Use
the shunt in combination with SDV-FL to detect undercurrent, reverse
current and overcurrent in DC circuits.
Note: Select a shunt whose rated current is more than 120% of the
82
For the dual-function SDV-DH3, the setting method given below would be used to detect over and
undervoltage with an AC voltage input. The intermediate voltage of dead band is 250 V and the dead
band voltage is 20 V.
Step 1. To set the detection method and type of input on the DIP switch.
Step 2. To set the intermediate voltage of dead band according to the BALANCE index scale
Step 4. Reset value for each detection setting: Automatically set according to the dead band
Step 3. To set dead band voltage according to the voltage multiplying factor and BAND WIDTH

current normally flowing in a circuit. The characteristics of the
shunt may change or fusing of a resistor element may occur if
an overload that is 1,000% of the rated current is applied.
Therefore, determine the rated current of the shunt to be used,
by taking the circuit conditions into account.
BAND WIDTH index scale value setting:
Turn the BALANCE knob to 2.5.
BALANCE index scale value setting: The calculation method is as follows for the BALANCE
index scale value (X = index scale):
Set the DEAD WIDTH knob to 0.2.
Reset values are calculated for overvoltage detection and undervoltage detection.

Voltage multiplying factor setting: The voltage multiplying factor is selected according to the
maximum and minimum factors and a sticker is attached. The calculation method is as fol-
value and the voltage multiplying factor.
Turn ON pin 1 (input) to specify a AC input.
Attach the OVER and UNDER INPUT AC stickers.

100 (Voltage multiplying factor) x X = 250 V (intermediate voltage of dead band)
Therefore, X = 2.5
The BALANCE index scale value is between 1.0 and 3.0, so calculate the voltage multiply
250 V (Intermediate voltage of dead band)/3 (BALANCE index scale value)

In this example, pins 2 and 3 are turned OFF and pins 4 is turned ON, and the x100V sticker
is attached.

250 V (Intermediate voltage of dead band)/1 (BALANCE index scale value)
= 250 (maximum multiplying factor)
Z (BAND WIDTH index scale value) x 100 V (voltage multiplying factor) = 20 V (dead band
voltage) Therefore, Z = 0.2
Overvoltage detection: Reset value = (250 V + 20 V)
Undervoltage detection: Reset value = (250 V
