PULS POWER 500W IP RATED FIEPOS POWER SUPPLY FOR RAILWAY TRACKSIDE SYSTEMS
The 500W FIEPOS power supply from PULS Power, the specialist manufacturer of high reliability DIN-Rail power supplies, is an ideal solution for decentralised electrical and electronic systems located trackside on railway networks
Traditional rail or 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. FIEPOS 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. Two versions of the high efficiency (>95%) PULS FIEPOS are available, both offering either 360W

rackside systems are typically mounted in location cabinets which can be open at the underside, making them prone to
condensation on the inside. Electronics systems mounted within location cabinets must be protected from the ingress of water and dust to ensure reliable long-term operation. This includes the power supply which is frequently located in the same ruggedised enclosure as other system components. Weatherproof enclosures are bulky and expensive, each adding extra cost and complexity to the end system. The PULS FIEPOS is a new type of power
supply that was developed specifically for this kind of environment. This is a decentralised power supply, requiring no additional enclosure, offering protection to class IP54, IP65 or IP6. FIEPOS power supplies are easy to install and flexible enough to meet the diverse requirements of modular systems. Removing the power supply (decentralisation) from shared enclosures saves space, reduces internal heat dissipation and allows the power supply to be conveniently located on an internal cabinet wall or DIN-Rail. Decentralisation of system components has
proven to be an important factor 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.

or 600W power output. The output voltage and the current-limited outputs (eFused series) can be monitored and set directly via the LED interface and the push buttons on the front of the device or remotely via IO-Link. The high-power single 24 - 28VDC output Basic Series FIEPOS can be connected in parallel with additional units to increase total output power. FIEPOS Basic can also be connected in a power back-up N+1 redundant system using integrated high efficiency MOSFET decoupling (Oring). The eFused series may be specified with
up to 4 current-limited DC outputs and may be configured for NEC Class 2 circuits. This power supply simplifies the implementation of selective power distribution, protection and monitoring directly in the field. The eFused series is a space-saving power supply system featuring integrated current-limited outputs and is a real 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. PULS FIEPOS power supplies may be used for the decentralised supply of 1-phase or 3-phase systems and machines and feature a no potting
• Waterproof, reliable, durable, flexible Decentralised Power Supplies • May be specified with IP54, IP65 or IP67 for reliable protection against ingress of dust and water • Local or IO-Link control
Eco-friendly modular design which may be specified with IP54, IP65 or IP67 for reliable protection against ingress of dust and water.
FEATURES Key features include an LED interface providing system status and immediate diagnosis in the field, output voltage and the current-limited outputs (eFused series) may be monitored and set directly via the LED interface and the push buttons on the front of the device or remotely via IO-Link. Various connector options enable the power supply to be installed flexibly and directly on the machine. DIN-Rail, integrated keyholes or screw mounting with no additional accessories required. FIEPOS is available with input voltage ranges 1-phase 85 - 264V, 1-phase 170 - 264V, 3-phase 320 - 550V, output voltage from 24 - 28VDC, output power 360W or 600W, efficiency > 95%, an operating temperature range from -25˚C to +55˚C without any loss of performance, and has dimensions (WxHxD) of 181 x 183 x 57mm. The potential applications of PULS FIEPOS
are virtually limitless and include modular applications in the field of rail, intralogistics, industrial control, conveyor systems, storage technology, robotics and materials handling.
