Emparro® 3~

Premium Power

Reliable and Efficient

Emparro 3-phase power supplies for 24V applications are important components in quality power management systems. These units are not only extremely reliable but also extraordinarily efficient as a result of their integrated reserved power. However, they don't require much space in the cabinet.


  • 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

Continuous 2-phase Operation

If one phase fails, the units continue to operate reliably with two phases, not just for a short time, but continuously.

High MTBF Value

Emparro67 has a high M value. MTBF describes the Mean Time Between Failures.

Even More Power

Connect up to five power supply units to each other to increase power, without having to adjust them regarding cable length and cross diameters. Parallel operation is activated by a switch – simple and convenient.

Startup with a single power supply

The device supplies up to 50% more power to start up higher loads and capacities without using a second power supply.

Protection from Overload Damage

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). This protects the power supply from damage.

Stable Output Voltage

Products that meet the Semi F47 standard ensure stable output voltage even during voltage drops.

A Global Player

The wide input voltage range makes Emparro suitable for worldwide use.

95% Efficiency Rating

A higher efficiency rating equals minimum power loss, which equals reduced operating costs. 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.

Clear Signaling

An alarm contact signals over voltage, short circuit, and temperature. An LED indicates the operating mode.
