Hello,

Welcome to our website for exploring and purchasing professional power supplies for your industrial automation projects. You can review the informative article we have prepared for you below to make the right power supply selection.

Our power supplies are presented in two separate categories: open-frame and enclosed (DIN rail mounted). Factors to consider when choosing a power supply include:

- Compatibility of input voltage and frequency (AC/DC)

- Number of devices requiring power supply

- DC voltage requirements of the devices

- Watt/amperage values of the loads to be used

- Maximum/peak current draw of each DC device

- Mounting and physical space requirements

- Checking applicable safety approvals and standards based on the intended use

Power calculation formula: Watt = Amp x Volt

Note: 1 amp corresponds to 1000 milliamperes (mA).

While most power supplies operate at 100% of their nominal capacity, it is recommended to use an extra 30% capacity. This allows the power supply to run cooler and more efficiently, extending its lifespan.

Example calculation:
Device #1: 24 Vdc, 2 Amps [24Vdc X 2A = 48 Watt]
Device #2: 24 Vdc, 1 Amp [24Vdc x 1A = 24 Watt]
Required total wattage: (24 + 48 watt) x 1.3 = 93.6 Watt

Round up to the nearest power selection, which will be 100 watts in this case.
In this situation, you should choose a power supply with a value of 100 watts and a 24-volt DC output.

Additionally, consider the following features when selecting a power supply:

- Short circuit protection

- Parallel connection compatibility

- Adjustable output voltage

- Flexibility of input supply voltage

- Network noise prevention quality

- Ambient temperature and efficiency relationship

- Warning LED lights (alert and operation status notification)

- Requirement to provide information to 3rd party receivers (relay or serial communication)

- Short-term load capacity against peak currents

Important reminder: If you are going to supply power to coil or ohmic loads with an electronic power supply (SMPS), especially in cases like a 24 Vdc 5 Amp motor power supply, you must choose a power supply with a 1x1.5 output, that is, 7.5 Amps. Motor loads can cause the power supply to collapse due to the starting current. Alternatively, you can create your own power supply using a transformer, bridge diode, and capacitor. Transformer-based systems may experience short-term collapses during startup, but this does not affect system performance.
