You could also speed up discharge
of the supply capacitor by connecting
a 1kΩ resistor across the supply on
the cathode (K) side of diode D3 to 0V
(GND), or directly across the capacitor.
Threshold voltage
switch for fridge
I built the Threshold Voltage Switch
(SILICON CHIP, July 2014) and enjoyed
building it. I have a solar panel on my
van’s roof, running an Engel fridge
104 Silicon Chip
inside with an Allrounder 120Ah
battery. The voltage varies quite a lot
between day and night as it is hooked
up to run permanently.
The fuse to run this fridge on DC
is gold-plated as they want A$50 to
replace it. I wonder if it would be possible to use your design without a lot
of modifications to switch the power
to the fridge off when a preset voltage
of say 11.7V DC occurs?
This would save me replacing the
fuse as the fridge cost is $A1000 in
the first place. (P. M, Rochedale South,
Qld).
• The Threshold Voltage Switch can

Worldwide Elect. Components... 103
be set to switch the relay at 11.7V. For
a refrigerator, you would need a relay
that can switch the necessary motor
current. It seems some Engel fridges
draw up to 4.2A but the peak current
could be a lot higher.
The 30A relays mentioned on page
32 of the July 2014 article should be
suitable. Whether the Threshold Voltage switch switches the relay on or off
is dependent on LK3’s position. VR3
adjusts the switching threshold. SC
