Switch Mode Power Supplies AC/DC

1-phase and 3-phase

Eco-Rail-2 power supply units offer manufacturers of machinery and control cabinets the possibility to supply power to their consumers flexibly and economically. These units provide basic functionality and help to monitor the overall costs in the control cabinet.

Available in different power ratings

The Eco-Rail-2 series is available in five units with power ratings from 1.3 to 20 A. The output voltage of the devices can be set from 23 to 28 V to supply the required power to the consumer regardless of the length of the power supply line. Connecting two power supply units in series allows the output voltage to be increased to 48 V.

  • Cost efficiency through an excellent price-performance ratio
  • UL approval enables worldwide use
  • Flexibility due to the range of versions and adjustable output voltage
  • Excellent mains failure bridging time of more than 40 milliseconds
  • Practical handling during installation and commissioning

The Emparro ACCUcontrol UPS module rounds out the high-performance Emparro power supply system. In the event of a power failure, it automatically switches to battery operation and prevents machine downtimes. Investing in a UPS system frequently pays for itself the first-time a stoppage is avoided.

External lead batteries with a capacity of up to 40 Ah ensure a long-lasting bridging period. The UPS module is available for 20 A or 40 A systems. Emparro ACCUcontrol can be assembled without the use of tools and is maintenance free. Because it is only 65mm wide, the 20A model needs very little space in the control cabinet.

Reliable power supply in the event of faults

  • Machine downtimes are prevented through uninterrupted switching to battery operation in power failures
  • Maximum lifetime through temperature-controlled battery charging
  • High operational reliability through comprehensive control and diagnosis options with predictive maintenance
  • A shutdown function for IPCs prevents data loss with easy-to-use computer software

The Emparro HD switched power supply is designed for use in particularly tough environments to guaran-tee a reliable supply of electricity.

The preferred application areas for Emparro HD are areas in which power supply units may be installed in a control cabinet, but are still exposed to a variety of external influences, for example on spreaders (lifting equipment for moving containers), construction cranes, and systems of internal conveyor technology. The power supply units are often found on movable parts and are exposed to high induction voltages or weather elements, like extreme temperatures and high air humidity.

Emparro HD provides reliable power in extreme conditions

  • High vibration and shock resistance thanks to encapsulation and compact design
  • Maximum overvoltage resistance as effective protection against voltage peaks like nearby lightning strikes
  • Tool-free connection technology through oversized leash terminals
  • High efficiency even at extreme temperatures of −40 to +80 °C

Murrelektronik's Emparro switch mode power supply units' efficiency rate of up to 95% is impressive! This reduces power loss to a minimum and the low energy consumption helps save a lot of money.

Efficiency up to 95%

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

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

Emparro67 power supply units are designed for applications in the field. They are durable enough to withstand even the most extreme environmental conditions. Emparro67 significantly reduces power loss and lowers energy costs because they can be installed directly next to the load where the conversion from 230 V AC to 24 V DC takes place. Another benefit is that you can use smaller control cabinets.

Decentralized Solutions

  • 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
  • Flat, compact design

Buffer Modules

A Guarantee for High System Availability

Voltage drops can cause unpleasant effects: interrupt production processes, cause downtime, and require a system resets. They may even cause data loss and machine damage. Murrelektronik's buffer modules protect power supplies by bridging the time without power supply or enabling a controlled shut down of machines connected to a PC.

  • Controlled Shut-Down: A controlled shut down of industrial PCs is necessary to avoid data loss and damage to controls, PCs, machines and systems. The necessary software is available in the online shop.
  • Ultra Capacitors: Ultra capacitors make buffer modules very cost-effective. They are maintenance-free for life. Expensive service work to change the batteries becomes a thing of the past.
  • Buffer time up to 38 seconds under full load
  • Signal contacts give latest status
  • Maximum system uptime
  • Slim design
  • Wide temperature range from -40°C to +60°C
  • LEDs directly on the module
  • cULus listed and GL approvals
  • Product range from 3, 10, 20 and 40 A
