New power supplies accommodate 150 percent start-up loads

27 November 2012

Murrelektronik's new high-efficiency Emparro power supply unit features a 'Power Boost' function that provides easier starting of large loads.

Emparro's efficiency rating is up to 95 percent so it generates less heat, increasing its lifespan and reducing the thermal stress on adjacent components. The novel Power Boost feature, meanwhile, provides as much as 150% more power for up to 4 seconds, accommodating high start-up loads.

In addition to Power Boost, the power supply features both short circuit and overload protection with appropriate alarm contacts for remote diagnostics.

A wide input voltage range from 85 to 265Vac (90 to 250Vdc) makes Emparro suitable for worldwide use.

The unit is available in seven different models, with output voltages of 12, 24 and 48V, and can be operated over the temperature range -25 to +60°C without derating.
