Can Your Power Supply Survive an Apocalypse?!
As we live in an era of technology, the power supply has become an essential component of our everyday life. Power supplies are designed to be durable and reliable, yet they may not be able to withstand extreme environmental factors. When it comes to an apocalypse where the world is devastated by natural disasters or human-made threats, can your power supply still survive? In this blog post, we will explore the durability of power supplies concerning extreme weather, electromagnetic pulses, and long-term power outages.

Extreme Weather
One of the biggest threats to your power supply during an apocalypse is extreme weather. Weather conditions can range from hurricanes, tornadoes, earthquakes, and floods, to radical temperature changes, such as heatwaves and blizzards. These weather conditions can cause power outages that could last for days, weeks, or even months.
Most power supplies, particularly the ones located outside or in areas prone to extreme weather, are designed to survive these conditions. Power supplies have ratings that help identify their resistance to environmental factors. They are rated based on the International Electrotechnical Commission (IEC) 60529 standard, which classifies their level of protection against dust, water, and solid objects.
Power supplies that are rated IP65 are designed to withstand harsh weather conditions. These power supplies have sufficient protection against water and dust that can interfere with their conductive and mechanical functions. They can handle rain, snow, and wind. Power supplies that are rated higher than IP65, such as IP67, IP68, or IP69, are more durable and can withstand longer and more extreme exposure to weather conditions.
Electromagnetic Pulse (EMP)
An electromagnetic pulse (EMP) is a burst of electromagnetic radiation that can be caused by nuclear explosions, solar storms, or lightning. EMP can cause serious damage to power grids, affecting the power supply and all electronics connected to it. An EMP can cause blackouts that could last for weeks or months.
The good news is that power supplies do not directly absorb EMP. While it can damage the power grid, it does not affect every electronic device within it equally. The extent of the damage caused by an EMP relies on its magnitude, distance, and duration.
Most electrical and electronic devices have built-in protections, such as fuses, surge protectors, and filters, that can protect them from EMP damage. For example, power supplies that incorporate Electro-Magnetic Interference (EMI) filters protect their components from external electromagnetic disturbances that could cause malfunctions.
Long-term Power Outages
A power outage is the disruption of electrical power to a network, causing a blackout that could last for minutes, hours, or even days. A long-term power outage resulting from an apocalypse could last for months or even years. Power supplies in such situations could be exposed to variable power input and output conditions leading to their immediate or eventual failure.
In such situations, people rely on Backup Power Systems (BPS) such as Generators, Batteries, and Fuel Cells. BPS systems should be chosen according to their intended use, based on the following criteria:
– Quantity of electrical power requirement
– Expected duration of the outage
– Availability of the fuel
– Size and weight restrictions
– Budget
In addition to BPS, you should also consider using Uninterruptible Power Supply (UPS) systems that prevent power disruptions during utility power outages, such as power fluctuations and surges when switching between utility power and generator power.
Conclusion
As we have seen, power supplies are designed to be durable and reliable, yet they may not be able to withstand extreme environmental factors. Weather events, EMPs, and long-term power outages can be devastating, but there are ways to keep your power supply intact. Use a power supply rated IP65 or higher, equip your electronic devices with EMI filters, and use a combination of BPS and UPS systems to keep your equipment alive during an apocalypse.
FAQs
Q1. Can a Power Supply Resist EMP?
A1. While power supplies can be damaged by EMPs, they are not as vulnerable as other electronic devices. They have built-in protections such as fuses, surge protectors, and EMI filters that protect them from EMP-related damages.
Q2. Can I Use Any BPS for a Long-term Outage?
A2. No. You should choose a BPS according to the equipment you plan to use, the expected duration of the outage, and the availability of fuel.
Q3. What is the best rating for a Power Supply?
A3. The best rating for a power supply is a rating of IP67 or higher. These power supplies have sufficient protection against water and dust and are durable enough to handle harsh weather conditions.
