Mean Well
DIN-Rail Power Supplies
Mean Well DIN-Rail power supplies are renowned for their reliability, efficiency, and versatility in industrial and automation applications. These power supplies are designed to be mounted on DIN rails, a standard mounting rail widely used for industrial control equipment inside equipment racks.
Mean Well's DIN-Rail power supplies are available in a range of power ratings and output voltages, ensuring compatibility with various systems and requirements. They feature robust construction, high efficiency, and protections against overload, short-circuit, and over-voltage, enhancing system safety and longevity.
Additionally, their compact design and easy installation make them a preferred choice for engineers and technicians seeking dependable power solutions for industrial environments.
Essential Guidelines for Selecting a Power Supply
The output voltage of the power supply must align with your hardware’s voltage needs. If it’s too high, it could damage your hardware. Conversely, if it’s too low, it may prevent your hardware from functioning optimally.
Your device will only draw the necessary watts and amps, so having a higher value available can help avoid brownouts (brownouts occur when hardware doesn’t perform as expected due to insufficient current).
Power Supply Rules
- Voltage output should match with the voltage needs of the equipment it is intended to power.
- Wattage rating should meet or exceed the energy demands of the equipment it will power.
- Amps should meet or exceed the energy demands of the equipment it will power.
Reading Device Power Requirements
All our available products include a copy of the manufacturer's datasheet, detailing specific features and requirements for each product. Here you can find details of the Power Input needed to run the device at its optimal performance, but this often only shows two of the three power requirements, the third can easily be calculated with the basic formula that Amps multiplied by Volts equals Watts.
Example - Advantech EKI-2525
| Power Parameters | |
|---|---|
| Power Consumption | 2.88 Watts |
| Power Input | |
| Fault Output | |
VDC (Volts Direct Current) = Range from 12 to 48
Watts = 2.88
We could calculate the following best recommendations
12V = 3W and 0.25A
24V = 3W and 0.125A
48V = 3W and 0.067A
Example - Moxa EDS-2008-ELP
| Power Parameters | |
|---|---|
| Connection | 1 removable 3-contact terminal block(s) |
| Input Current | |
| Input Voltage | |
| Operating Voltage | |
| Overload Current Protection | |
| Reverse Polarity Protection | |
VDC (Volts Direct Current) = Choose from 12, 24 or 48
Amps = 0.067 (when using 24VDC supply)
We could calculate the following best recommendations
12V = 1.6W and 0.14A
24V = 1.6W and 0.067A
48V = 1.6W and 0.04A
When comparing these power requirements to our available range, you can see there are many options available that would satisfy all porducts available on our store but we know this is only the first thing to consider.
More often than not, you will have several devices all in the same cabinet or rack, that all need to share the same AC to DC power source with varying current (Watt & Amp) demands, and that’s when having multiple options with different VDC outputs available really makes the difference.
Connect in Serial vs Parallel
When it comes to connecting multiple devices to one shared power supply, these are two main types of circuits, although these can be mixed for more complex power circuit.
Series Circuits
In a series circuit, all components are connected in line with each other.
- Current is the same in all parts of the circuit. Current is not ‘used up’ along the circuit, so remains constant.
- Total voltage is shared amongst components. The total voltage from the power supply is shared between the devices – if the supply provides 24V of energy, and there are two switches with equal requirements, each will get 12V.
Parallel Circuits
In parallel circuits, the components are connected in separate loops.
- The voltage is the same for all components and remains constant.
- The current being provided by the power supply is shared between the branches of the circuit.
- With the added advantage that a break in one component or cable does not ruin the whole circuit. There is more than one route for charge, so if one device in a parallel circuit is broken, only the devices in the broken branch are affected.
