Single-phase switching power supply with DIN-rail, designed specifically for applications in command and control panels for industrial automation and process control. Capable of delivering +60% to +80% nominal current for a prolonged period of time while maintaining a constant output voltage and equipped with a voltage threshold-controlled failure contact which is triggered when the voltage drops below 90% of the rated value. With these features and numerous international certifications, this range of power supplies enables designers to meet the requirements of the Machinery Directive EN 60204-1, allowing the protection devices connected to the output to trigger quickly, safely and selectively, thus ensuring continuity of service to the other parts of the system.

Suggested uses

• Applications in industrial automation with high performance and reliability requirements.
• Applications which require selectable overcurrent protections on DC lines
• Applications in machine automation with high command and control voltage reliability and safety requirements
• Applications in process control
• Uses with heavy loads
• Civil automation applications

Main features

• The 90…264 Vac and 110…370 Vdc inputs, make it suitable for use on all power supply networks. 
• Threshold failure contact which is triggered when the voltage falls below 90% of the rated value.
• Versions with integrated ORing diode for redundant parallel connection, preventing the need for external devices and reducing bulk and installation costs.
• High efficiency reduces energy consumption and the operating temperature of components and allows use in small panels and severe environmental conditions. 
• Large power reserve allows for delivery of at least +60-80% nominal current and voltage for several minutes, ensuring safety and reliability.
• Output voltage is adjustable and the output is protected against input surge from the DC line generated from inductive loads.
• The output is equipped with dual electronic protection which prevents dangerous voltages for powered components in the event of an internal fault.
• Thermal protection prevents faults in case of prolonged overload with high ambient temperatures.
• Construction ensures excellent ventilation capacity of internal components, with reduced sizes and a degree of protection from accidental contacts of IP20 per IEC529.
• Thanks to their high performance and excellent ventilation capacity, they are among the smallest on the market.

48Vdc and 72-85Vdc models have been
introduced, designed to reliably power
engines in DC. They:

• supply peak power equal to even
  4-5 times the nominal current,
  which is required by the engine
  during the peak phase
• have an output stage protected
  from overvoltage generated by the
  engines and drives during braking,
  which could otherwise cause malfunctions or cause the power supply to lose control over output voltage stability.
