You can view our Power Supplys for industrial automation projects here.
It is divided into 2 categories as Open type and Closed type (rail mounted).
Power Supply The following factors should be taken into account when choosing.
- Power supply, input voltage and Frequency (AC/DC)
- Number of receiving devices that need power supply
- DC voltage requirements of receiving devices
- Watt/Amperage of the loads to be used
- Maximum/Peak draw of each receiving DC device
- Available physical space and assembly requirements
- Check the applicable safety approvals for the location and application (for example, the required standards for medical machinery or defense industry are different from others)
Converting Volts to Watts; It is governed by the equation Watts = Amps x Volts.
Note: 1 amp is equivalent to 1000 milliamperes (mA).
While most power supplies allow operation at 100% of rated capacity, it is recommended to use an extra +30% capacity. This keeps the power supply running cooler, more efficiently and extends its lifespan.
For example: Let's consider a receiving device that requires 2 separate feeds;
Device #1 requires 24 Vdc and draws 2 Amps [24Vdc X 2A = 48 Watts]
Device #2 requires 24 Vdc and draws 1 Amp [24Vdc x 1A = 24 Watts]
Total watts required (24 + 48 watts) x 1.3 = 72 Watts
Round up to the nearest power selection and it will be 80 watts.
Therefore, you choose a power supply rated at 80 to 100 watts and with a DC output of 24 volts.
+ Whether there is short circuit protection or not
+ Does it allow parallel connection?
+ Is the output voltage adjustable?
+ How flexible is the input supply voltage?
+ Quality of grid interference measures depending on the intended use
+ Ambient temperature (power supplies lose efficiency as environmental temperature increases)
+ Are there warning led lights (warning and working notification)?
+ Do you need information from 3rd party receivers for relay or serial communication?
+ Can its loadability continue even for a short time against peak currents?
++ Important reminder; If you are going to supply coils, that is, for ohmic loads, with an electronic power supply (SMPS), let's open it further, for example, if you are going to feed any 24vdc 5 Amp motor, you should definitely choose 1x1.5, ie 7.5 Ampere output. Motor loads can cause your power supply to crash due to the starting current. Or you should make a power supply yourself with Transformer + bridge diode + capacitor. systems with transformers may crash during startup, but the system does not pause because it is short-lived.
