■ Designing Power Circuit
Since many documents and reference books on the power circuit are
available, a detailed description is omitted here.
■ Connection of Surge
Note: This graph is plotted by measuring the surge voltage in the line
When connecting a surge suppressor, pay attention to the following
points:
1. Place the surge suppressor near the device to be protected. For

example, to protect a device from external surge, set the surge
suppressor at the inlet of the device’s power cable.
To suppress an internal surge, the suppressor must be placed
near the surge generating source.

power circuit elements, as well as elements related to the
power circuit, in case the voltage on the power line experi-
ences surges (due to lightning or the surge voltage gener-
ated in other devices connected to the power circuit).
Connect an appropriate surge suppressor across the output
terminals of the power circuit to prevent a surge voltage
from being generated. The surge suppressor must keep the
surge voltage, if generated, from exceeding the breakdown
voltage of each element in the power circuit.
that flows through the power circuit upon power application.
Although the resistance of R is determined according to the
resistance of the load coil and the ratings of the diodes, the
use of a resistor having a resistance of 0.1 to 100Ω is rec-
ommended.

■ Countermeasures Against
In case the supply voltage fluctuates heavily, insert a regulated volt-
age circuit or constant-voltage circuit in the application circuit as
shown below.
Relays consume more power than semiconductor elements. The fol-
lowing circuit configuration is recommended to improve the charac-
teristics.

sufficiently withstand the surge current. The short length and thick
diameter are important to reduce the inductance and generated
voltage, and to protect the device from heat damage.

the protective effect of the surge suppressor. Perform grounding
at a ground resistance of 10Ω or less.
