PULS Power has developed a 500W flexible, modular point of load power architecture for industrial automation and process engineering applications.

The ZeroCabinet was developed specifically for decentralised point of load power in harsh industrial applications, potentially replacing control cabinets. The decentralised power supply with protection to class IP54, IP65 or IP67 that is available ex stock, is easy to install and flexible enough to meet the diverse requirements of modular factory automation such as conveyor systems, storage technology, robotics, control systems and materials handling.

Traditional industrial  systems designed with a central IP20 rated power supply will have long cable runs to peripheral devices in the field and will require costly large cross-section cables to minimise losses. It is also common for such a power supply to be over specified to compensate for any potential cable losses.  ZeroCabinet provides an energy efficient, point of load, modular system structure which is simple to expand and maintain.

There are two versions of the PULS ZeroCabinet available with either 300W or 500W power output, measuring 181 x 183 x 57mm. The high-power 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 in an O-ring.

The eFused series may be specified with up to 4 current-limited DC outputs and may be configured for NEC Class 2 circuits. This simplifies the implementation of selective power distribution, protection and monitoring directly in the field. This provides integrated current-limited outputs and is an alternative to a power supply unit with an external electronic protection module. Special features include staggered output activation, protection of sensitive loads through prioritised outputs and selective shutdown in the event of a fault.

The ZeroCabinet power supplies may be used for the decentralised supply of 1-phase or 3-phase systems and machines and feature a no potting Eco-friendly modular design which may be specified with IP54, IP65 or IP67 for reliable protection against ingress of dust and
