Industrial PoL is based on decentralised power supplies

To meet the growing need for flexible, modular power systems for machine building and process engineering, PULS Power has recognised that decentralisation of system components is critical in modern system planning as it simplifies installation, enables expansion and reformatting of systems, and simplifies maintenance. In addition, conventional control cabinets can be replaced by smaller versions or even removed completely, says the company.

PULS has introduced the ZeroCabinet decentralised power supply with protection to class IP54, IP65 or IP67. It is available ex stock and is easy to install and flexible enough to meet the diverse requirements of modular factory automation, the company says.

ZeroCabinet is the alternative to a power supply in a centralised control cabinet. It provides an energy efficient, point of load, modular system structure which is simple to expand and maintain. ZeroCabinet makes it possible to use shorter and smaller cross-section cables which reduces both the cost of cabling and of its installation. The integrated power supply can be used instead of several components simplifying system design and reducing inventory, adds the company.

There are two versions available, both offering either 300W or 500W power output.

The high-power singe DC output Basic series ZeroCabinet, can be connected in parallel to increase total output power or form an N+1 redundant system using integrated high efficiency MOSFET decoupling (Oring).

The eFused series may be specified with up to four current-limited DC outputs and may be configured for NEC Class 2 circuits. It simplifies the implementation of selective power distribution, protection and monitoring directly in the field with integrated current-limited outputs. The space saving power supply also has an external electronic protection module. Other features include staggered output activation, protection of sensitive loads through prioritised outputs and selective shutdown in the event of a fault.

PULS ZeroCabinet power supplies may be used for the decentralised supply of single or three-phase systems and machines. The no potting eco-friendly modular design may be specified with IP54, IP65 or IP67 for reliable protection against ingress of dust and water.

Key features include an LED interface providing system status and immediate diagnosis in the field, output voltage. The current-limited outputs in the eFused series may be monitored and set directly via the LED interface and the pushbuttons on the front of the device or remotely via IO-Link. A choice of connector options enable the power supply to be installed flexibly and directly on the machine.

ZeroCabinet is available with input voltage ranges single-phase 85 to 264V, single-phase 170 to 264V, three-phase 320 to 550V, output voltage from 24 to 28V DC, output power 300W or 500W. With 95 per cent efficiency and an operating temperature range of -25 to +55 degrees C without any loss of performance and compact dimensions of 181 x 183 x 57mm, the ZeroCabinet can be used in various applications, including conveyor systems, storage technology, robotics, control systems and materials handling.
