The maximum output current for the Phoenix Contact STEP-PS/ 1AC/12DC/1 is 1 Ampere (1A).
No, this power supply specifically outputs 12V DC. It is not suitable for systems requiring 24V DC. Phoenix Contact offers other models for different voltage requirements.
This power supply is designed for DIN rail mounting (35mm standard) and can also be screwed onto a flat surface.
Please refer to the official Phoenix Contact documentation or your point of purchase for specific warranty information, as it can vary by region and reseller.
No, this is an indoor power supply with an IP20 protection rating. It should be installed in an enclosure to protect it from dust and moisture.
It holds numerous certifications including EN 61000-6-2, CUL, EN 61558-2-16, IEC 60950-1 (SELV), EN 50178 (PELV), and is RoHS compliant.
The high efficiency (up to 83%) means less energy is wasted as heat, leading to lower electricity bills and a cooler operating environment within control cabinets, which can prolong the life of other components.
Verify that the input voltage is within the 100-240V AC range. Check that the AC input wires are securely connected to the L and N terminals. Ensure the DC output wires are correctly connected to the + and - terminals.
Confirm that the connected load does not exceed the 1A maximum output current. Check for loose connections on the output terminals. Ensure adequate ventilation to prevent overheating, which can cause voltage regulation issues.
Ensure the power supply is installed with sufficient clearance for ventilation. Check that the ambient operating temperature is within the specified -25°C to +70°C range. Verify the load current does not exceed the 1A rating.
Inspect all input and output connections for tightness and corrosion. Check the stability of the AC input power source. Consider the possibility of an overload condition if the failure occurs when the load is active.
Setup: This power supply is designed for primary switching and mounts directly onto a standard DIN rail (35mm). Ensure the unit is installed in a location with adequate ventilation, respecting the operating temperature range of -25°C to +70°C. Connect the AC input (L and N terminals) to your mains supply (100-240V AC) and the DC output (+ and - terminals) to your 12V DC load. The unit is IP20 rated, meaning it should be installed in an enclosure to protect against dust and accidental contact.
Compatibility: The STEP-PS/ 1AC/12DC/1 is compatible with standard AC power sources within the 100-240V range and is suitable for powering 12V DC devices that draw up to 1A. It complies with numerous international standards, including EN 61558-2-16 and IEC 60950-1 (SELV), making it suitable for a wide array of industrial and building automation applications.
Care: To maintain optimal performance and longevity, keep the ventilation slots clear of dust and debris. A periodic visual inspection of connections is recommended. Cleaning should be done with a dry or slightly damp cloth; avoid using solvents or abrasive materials. Ensure the unit is powered off and disconnected from mains before any cleaning or inspection.
