COVER STORY FEATURE ON-MACHINE POWER SUPPLY
Emparro67 is used in the field on the machine. The robust and fully molded switch-mode power supplies with a protection class of IP67 can resist even the most extreme environmental conditions. The voltage is converted from 230 VAC to 24 VDC directly on the machine. This keeps power losses to a minimum and reduces energy costs. Since hardly any energy is converted to heat, the devices can be touched even when operating at full capacity. They function reliably up to ambient temperatures of 85˚C. Relocating the power supply to the machine creates space in the control cabinet. The Emparro67 is also resistant to dirt, moisture as well as coolants and lubricants.
SUPPLYING POWER IN A ROUGH ENVIRONMENT
EMPARRO67 HYBRID SUPPLYING POWER IN THE FIELD
Supplying Power, Protection and Communication On the Machine!
Two integrated channels for 24-VDC load circuit monitoring ensure high operational reliability. An IO-Link interface supports communication, for example, during device parameter changes or when reading diagnostic data for predictive maintenance.
Emparro HD
PERFECT FOR OUTDOOR CONTROL CABINETS
Emparro HD is a switch-mode power supply module designed for applications where the control cabinets are exposed to outside influences, for example, on movable parts on spreaders, construction cranes or materials handling machinery.
• High vibration and shock resistance
• Maximum overvoltage resistance protects against voltage peaks or lightning strikes nearby
• High level of efficiency even at extreme temperatures ranging from -40 to +80˚C

DESIGN SOLUTIONS | JUNE 2018 7
When following our zero cabinet concept and relocating functions from the control cabinet directly onto the machine, our customers can make control cabinets smaller and, in some installations, even eliminate them entirely. One benefit of moving a switch-mode power supply out of the cabinet and onto the machine is that it eliminates a heat source which means the cooling system can be smaller. It also reduces wiring time and effort. The voltage is converted directly where the power is
being consumed, which has a positive impact on the energy balance. The idea of offering switch-mode power supplies for on-machine use is forward-looking but also logical because we are taking decentralization to the next level. We have a complete portfolio of field components, ranging from the sensor/actuator level to the control unit level. The expertise required to produce a switch-mode power supply for on-machine use in a harsh industrial environment has been a major development in the world of switch-mode power supplies.”
