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 Wiltronics........................................ 7 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 siliconchip.com.au
