400…500 Vac 3-phase switching power supply for industrial automation applications. They can deliver over +50% of nominal current for a sustained period, keeping the output voltage stable and ensuring continuity of supply to the system. Equipped with voltage threshold controlled failure contact which is triggered when the voltage falls 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 machine automation with high command and control voltage reliability and safety requirements
• In applications which require selectable overcurrent protections on DC lines
• Industrial automation applications
• Uses with heavy loads

Main features

• With 340…550 Vac/507…770 Vdc input, making them suitable for use on all power supply networks. 
• 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 +50% of nominal current for 5 seconds maintaining the output voltage stable, ensuring safety and reliability.
• Output voltage is adjustable and protected against incoming surge from the DC line, and is equipped with a double electronic protection that prevents damage to the powered device in case of an internal malfunction.
• Short-circuit and overload protection designed to deliver peak currents more than 150% higher than the rated value required by heavy loads.
• Thermal protection prevents faults in case of prolonged overload with high ambient temperatures.
• Construction ensures optimal capacity of ventilation of internal components, extremely reduced overall dimensions and degree of protection IP20 by accidental contact according to IEC529.

Special power supplies for engines DC, Brushless, and relative drives

New 48Vdc, 72-85Vdc, and 110-180Vdc 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 mal-functions or cause the power supply to lose control over output voltage stability
• Provide output voltage at 48Vdc, and 72…85Vdc. By increasing the voltage of the engine power supply, the same power can be obtained at lower current, with notable ad-vantages for performance, engine construction, connection wires, and drives.
