Overview of Modular Power Supplies
Before we get into the best modular PSU for your unique needs, let’s take a step back. Do I need a modular power supply in the first place? It all depends on your specific operation’s power requirements.
The main design feature that separates these from other styles is their configurability. Each unit consists of a primary frame that houses several slots.
These accommodate a range of modules, each designed to deliver different voltages or currents. You can mix and match these modules to create a power supply that meets your specific needs.
As you can imagine, this opens up a world of possibilities that traditional power supplies don’t offer. Here’s an overview of the advantages of a modular vs non-modular power supply:
- Flexibility and Scalability: Adding or removing modules as needed allows businesses to adapt without the need to purchase new power supplies. This cost-effective approach minimizes electronic waste and hassles associated with power supply replacement.
- Ease of Maintenance and Upgrades: Noticing the signs of faulty power supply can be stressful, but problematic modules can be replaced without shutting down the entire system, keeping downtime to a minimum. Upgrades involving simple module swaps instead of complete system overhauls.
- Improved Airflow and Cooling: Modular PSUs offer better airflow around the components since they only occupy the necessary space within the chassis. This helps prevent PSU overheating and can lead to a longer power supply lifespan.
- Reduced Cable Clutter: With only necessary connections in place, these units promote a cleaner, more organized setup, which not only improves ventilation but also reduces potential RFI sources. It just plain looks better, too.
Of all the different types of power supply, this is the most popular we sell here at Bravo Electro - and it’s clear to see why. That being said, let’s take a look at what matters most in selecting the best fully modular power supply so you can shop with confidence.
What to Look for in the Best Modular PSU
We know that choosing the best modular PSU can be overwhelming, but that’s where we come in. Whether you’re looking for a standard off-the-shelf unit or you need a custom solution, we encourage you to simply reach out today and let us guide you toward the perfect pick.
In the meantime, here are the most important considerations as you start your search for the best modular power supply, from power supply specifications to power supply certification.
Power Capacity and Scalability
Start by evaluating the total power requirements of your operation. Consider not only the immediate needs but also potential future expansions. We have tips on how to check PSU wattage and PSU voltage in our blog.
Ensure the power supply can accommodate all the different modules you need, too - whether it’s 2, 3, 4, or more. You should also think about the different power supply connector types to ensure the unit aligns with your specific operation.
Build Quality and Durability
Industrial environments can be harsh - you need to invest in a unit that can withstand these conditions without failure. Fortunately, this isn’t a concern when you source from our harsh environment power supply section.
Choose power supplies that are built to withstand conditions such as vibrations, dust, and fluctuations in temperature. High-quality materials and solid construction are an investment in longevity and uptime.
Cooling capabilities are also important, so look for built-in mechanisms such as fans or heat sinks to keep the unit operating within safe temperature ranges.
Regulatory Compliance and Safety Features
For many applications, like powering medical equipment, the specific industry standards and certifications a power supply adheres to are just as important as actual compatibility when choosing the best fully modular powe supply.
You may need a class 2 power supply or a UL listed power supply, or perhaps both. Some more specific safeties to seek out are ITE 62368 for industrial uses or 2xMOPP for medical uses. We even have a full medical power supply collection here at Bravo Electro.
Other features for protecting the unit itself include over-voltage protection, short circuit protection, and over-temperature shut-off. These prevent damage to the power supply along with connected equipment.
Brand Reputation and Support
We recently wrote about the best power supply manufacturers, because there are so many excellent brands to choose from. The good news is that you don’t have to worry about this when you shop with us for the best modular PSU, as we’ve carefully curated a catalog featuring only the most respected brands.
But if you’re looking for a specific recommendation, MEAN WELL is highly touted as the industry’s trusted choice. You can’t go wrong with IPD, Cincon, Autec, or I-Star either, though.
From a support standpoint, this is something you can rely on Bravo Electro directly for when you shop with us. We have a world-class customer service team on staff along with electrical engineers for more complex inquiries.
This is to say that no matter which power supply you order on our website, you never have to worry about getting help. We take great pride in our reputation for providing excellent service.
Cost Considerations
You may be wondering…why are power supplies so expensive? Think back to all the benefits we discussed - many of which involve cost savings. In other words, you get what you pay for. So rather than shopping based on price, think about the value you’re getting in a unit.
If it saves you costs down the road on upgrading your system, or its efficiency cuts your energy bill, or it even just offers you peace of mind knowing you don’t have to stress about downtime, it’s worth paying a bit more.
