■ Countermeasures Against
If a load such as a capacitor or lamp through which an inrush current
flows is connected to the power source and contact of the relay, the
supply voltage may drop when the contact is closed, causing the
relay to abnormally release.
Increasing the capacity of the transformer or providing an additional
control circuit can be used to prevent this drop in the supply voltage.
On some occasions, use of the following circuit may prevent voltage
drop.
The same circuit also applies when the relay is driven by a battery.
■ Designing Power-Conserving
This section introduces a patented drive circuit for the single-winding
latching relay that can be driven on several milliwatts. This drive cir-
cuit not only allows the relay to be used in the same manner as semi-
conductor devices but also offers a wide range of applications.
Operating principle
Set
When a specified voltage is applied across E, the current flows
through the circuit in the sequence of diode Di1, capacitor C, relay
Ry, and diode Di2. C is then charged, setting the relay.

Technical Information
Energization
When C has been fully charged, the relay is biased by the current
flowing from Di1 to Rb. C does not discharge. The power consump-
tion at this time is very small, several milliwatts at best, and its value
can be calculated as follows:
P =
where,
P: power consumption
V
The current that is to flow through Rb at this time is dependent on the
transfer ratio h
Reset
When the voltage placed across E is removed, the electricity charged
in C is discharged, causing the current to flow through the circuit in
the sequence of Rb, the base, and the emitter of TR. In this way, the
relay is reset by the current flowing in the direction opposite to when
the relay is set.
The following equivalent circuits respectively illustrate the current
flows when the relay is set, energized, and reset.

Circuit design
Fundamental
Generally, the latching relay is set and reset when a pulse having a
square waveform is applied to it for a short time. The minimum pulse
width required to set and reset the relay is predetermined.
The charging current shown in the above equivalent circuit diagrams,
has a sawtooth waveform that can be expressed by the following for-
mula, because it is the primary circuit of C and R.
