The Pepperl + Fuch PS1000 Power Supplies have been created for industrial applications where high system availability, redundancy and efficiency are demanded. In industrial and process systems, control cabinets and field boxes, the PS1000 range of power supplies ensures a reliable and efficient power supply from 5 to 40 Amps, for 12 VDC, 24 VDC or 48 VDC output.
Designed with versatility and for extended use, the PS1000 Power Supplies feature ATEX, IECEx, and EAC approvals and can be utilised in applications up to ATEX Zone 2/Div.2. The extensive range includes 1 and 3-phase power supplies, redundancy modules and PSUs with built-in redundancy. Suitable for universal use across all sectors, including applications with stringent requirements on reliability and quality and providing optimal immunity to interference.
Reducing Costs and Improving Efficiency
The PS1000 power supplies have reliability built-in and are up to 95% efficient. This efficiency reduces the need for additional hardware, due to minimal losses in terms of the power fed in, minimising cabinet cooling and reducing energy costs.
Compact, the PS1000 takes up very little space and is easily mounted on DIN rails and can be used in ambient temperatures of up to +70 °C, the cable length can be compensated in the application as the output voltage is adjustable.
These versatile power supplies can be combined with other Pepperl+Fuchs DIN rail mounted devices in the control cabinet, including intrinsic safety barriers, signal conditioners and surge protection modules. When the input voltage is applied, the inrush current is actively limited, and networks and devices are protected. The ‘Peak Output Power function’ enables heavy loads such as motors and electronic devices to be switched on.

Redundant Power Supplies
Power supply redundancy is important for increasing system reliability. Industrial facilities depend on bulk power supplies as they power the control system architecture and the process measurement instrumentation. Business critical applications can’t afford to be offline due to a power supply failure which could lead to a substantial amount of lost revenue for every minute the process is down.
This need for system integrity and dependable performance in demanding conditions necessitates power redundancy. N+1 and 1+1 are two reliable redundancy methods that ensure system functionality even during a power failure.
N+1 and 1+1 Topology?
The PS1000 Power Supplies can be used redundantly in both an N+1 and a 1+1 topology. With an N+1 redundant configuration, multiple components (N) have at least one independent backup component (+1) ensuring continued functionality during power loss. All the modules in a configuration share the load and if a system module fails, the functioning modules continue to share the load without compromising system integrity.
The 1+1 configuration provides redundancy with 2 power modules of the same power coupled by a MOSFET to supply the same load. Using MOSFETs instead of diodes in the redundancy function reduces heat generation and the voltage drop between input and output.
Utilising Redundancy with the PS1000 Power Supplies
These capable power supplies can be used in redundant topologies by using an external redundancy module (PS1000 XXX. RM) that has a decoupling MOSFET on the input, allowing for the connection of 2 power supplies for 1+1 redundancy, or by using a (PS1000 XXX. R) power supply with a decoupling MOSFET for limited space applications.
For power applications requiring less than 40 Amps, 1+1 redundancy is an economical solution when a redundant power system is required, N+1 is for critical applications. The versions featuring IO-Link offer a future-proof interface that allows comprehensive diagnostics and configuration processes to be carried out during operation.
