  • 100% compatibility for global applications.
  • Durable units ensure system availability.
  • Murrelektronik experts will help you to create your perfect power supply system.

Murrelektronik Emparro67 SMPS power supply

Murrelektronik’s Emparro67 SMPS power supply units are specially designed for applications outside the control cabinet. They withstand extreme environmental conditions and can be installed directly in the field next to the loads. Power loss is reduced to a minimum because the voltage is converted from 230 V AC to 24 V DC directly at the load. Energy costs are therefore reduced and smaller cabinets can be used.

Features and benefits:

  • Low power loss.
  • High efficiency of up to 94.2%.
  • Active PFC.
  • Ambient temperature up to 85°C.
  • Extremely rugged, fully potted IP67 housing.
  • Contact-safe installation even under full load.
  • Very flat, compact design.

Murrelektronik Emparro switch mode power supply

Murrelektronik's original Emparro switch mode power supply units' efficiency rate of up to 95% reduces power loss to a minimum, ensuring considerable cost savings. In the event of overload, the output voltage is controlled with a constant current. It is limited to 100% of the nominal current or to 150% in Power Boost mode, which protects the power supply from damage. Emparro’s lower operating temperature ensures that the device, and the components installed around it, will not be as affected by heat build up in the cabinet. Therefore, control cabinets with smaller dimensions can be used.

Features and benefits:

  • 150% Power Boost for at least 4 seconds.
  • Metal housing with protective EMC characteristics.
  • Derating only at 60°C.
  • High mains failure bridging time.
  • Seven different models provide solutions for many applications.

Murrelektronik Emparro 3~ switch mode power supply

Emparro 3-phase switching power supplies for 24V applications are essential components in any quality power management system. Not only are they extremely reliable but also extraordinarily efficient. A higher efficiency rating means minimum power loss, which equals reduced operating costs. An alarm contact signals over voltage, short circuit, and temperature. Connect up to five power supply units to each other to increase power, without having to adjust cable length and cross diameters. Parallel operation is activated by a switch – it couldn’t be simpler or more convenient.

  • MTBF of about 1,000,000 hours.
  • Integrated gas discharge tube.
  • Up to 95% efficiency rating.
  • Permanently overload protected – up to 20%.
  • Power Boost function with 150% power for up to 5 seconds.
  • Hyper Boost function with 400% power for up to 20ms.
  • Minimum space required.
