Tips on Choosing the Right DIN-Rail Power Supply
If your application needs unparalleled reliability in a compact design, chances are, you can rely on DIN rail power supplies. But, not all units are created equal, from variances in power supply voltage to power supply specs, safeties, and more.
So, what power supply do I need? We’ll help you pick the optimal DIN rail power supply below, but remember - personalized assistance is just a click or call away at Bravo Electro.
Assessing Power Requirements
First, you need to determine the output voltage and power output necessary to support your equipment. Most industrial applications will fall into one of three voltages:
However, that’s not always the case, as you may need a 5v or higher voltage power supply. Always do your due diligence to confirm power requirements before you start shopping.
This is as simple as calculating the total wattage your devices will draw. Keep in mind that it’s often recommended to choose a power supply with a capacity that exceeds your total power requirement by 25-30% for reliable performance even under peak loads.
For systems with power demands that frequently fluctuate, make sure you’re getting a power supply with a wide output range and peak load capabilities to manage power surges without causing failure.
But, you need to make sure you’re taking note of the input voltage as well. DIN rail PSUs will fall into one of three ranges:
- Single-phase inputs are common in residential or small commercial setups, typically ranging from 85V to 264VAC.
- Two-phase or split-phase systems provide higher power delivery with two alternating current waveforms.
- Three-phase inputs are commonplace in industrial environments with high power requirements. These systems are more efficient and reduce the stress on individual wires, distributing the load evenly across three wires.
Making sure to account for each of these factors will deliver optimal performance and reduced energy loss for the most efficient power supply operation.
Environmental and Protection Factors
The setting in which you’re installing a power supply must be carefully considered as well. Temperature, humidity, and exposure to dust or moisture can all take a toll on the performance and longevity of your power supply.
So, take note of the operating temperature range of a power supply before you buy. Many are equipped to handle wide ranges from -30°C to +70°C. Other important protection features are:
- Overvoltage Protection to prevent voltage spikes from damaging sensitive equipment.
- Overload Protection to automatically shut down the power supply in case of excessive power demand.
- Short Circuit Protection to safeguard the system from potential electrical shorts that could cause overheating or equipment failure.
- Thermal Protection to prevent overheating by reducing the power output or shutting down the system if temperatures exceed safe levels.
You also need to choose the optimal IP (Ingress Protection) rating for your equipment, as this will keep sensitive electrical components safe from dust, water, or other particulates that could compromise the unit.
Efficiency and Power Factor Correction (PFC)
Choosing a highly efficient DIN-rail power supply reduces energy consumption, minimizes heat generation, and lowers overall operational costs. Many models are rated as high as 90% so that as little power is lost during the conversion process as possible.
Power Factor Correction (PFC) is a feature that reduces the difference between the power supplied and the power consumed by the load. It’s especially important for keeping industrial applications compliant with international energy standards while reducing energy wastage.
Power supplies with active PFC are also more resilient against harmonic distortion, so you can enjoy smooth and stable power delivery across your system.
Size and Form Factor
We’ve mentioned throughout this guide that DIN rail power supplies are inherently low-profile and compact, but the specific size and form factor will vary from model to model.
You need to ensure the unit you choose will fit seamlessly into your control panel or enclosure without overcrowding other components. Widths can be as narrow as 32mm in some cases.
Figure out whether you need a metal case for added durability or a plastic case for lighter-weight applications. This will depend on whether you’re more interested in protection against the elements or compactness.
Compliance and Certifications
Perhaps most importantly, make sure you are choosing a power supply that aligns with the specific compliance requirements for your use case. Here are some common examples:
- UL/cUL and CE certifications for general safety and electromagnetic compatibility.
- IEC 62368-1 for information technology equipment and industrial use.
- IEC 60601-1 certification for compliance with stringent medical safety standards.
- TUV and CB certifications to confirm that the power supply meets global safety standards.
