as lifting and rotating units in conveyor systems are converted from pneumatic to electric drives, a decentralised and protected power supply is ideally suited. In order to realise this, space-saving and powerful power supplies with sufficient power reserves are needed directly in the field. Long, loss-prone supply lines are eliminated, and flexibility is increased. PULS has developed the product category ‘Field Power Supplies’ for this purpose, which consists of 360 W and 600 W power supplies with high protection classes IP54, IP65 and IP67, as well as many different connector options.
Additional features, such as up to four integrated current-limited outputs, ensure the safety of electrical consumers. With these eFuses integrated into the power supply, it is possible to realise selective power distribution, protection, and monitoring outside the control cabinet. The Field Power Supplies are very robust both mechanically and electrically, and resistant to harsh environmental conditions such as moisture, dust exposure, and vibrations.

PULS power supply solutions for the automotive industry.
Sufficient power reserves for dynamic motion sequences For cobots, smaller robots, and decentralised applications in the automotive industry, electric drives have
also become the first choice.
A reason for that is also the significant technological advances in electric motors. In recent years, these have contributed to making electric drives a real alternative to pneumatics. The motors generate a lot of power with small dimensions and weight. However, the rapid movements that electric motors enable, for example in robotic applications, require power supplies that can not only handle higher loads in the short term but also process the resulting regenerative energy. Many PULS power supplies have generous power reserves, known as BonusPower. Numerous DIN rail power supplies from the proven DIMENSION product family provide up to 150 per cent power for four seconds. The FIEPOS field power supplies also achieve 200 per cent power for five seconds thanks to BonusPower. Upcoming product families for DIN rail mounting, currently in development, will even surpass these values in terms of peak performance and dynamics.
Thanks to the generous power reserves, oversizing of the power supply is unnecessary, resulting in cost and space savings.
Wireless charging of autonomous guided vehicles and mobile robots Loss-prone pneumatic drives are becoming increasingly rare in autonomous guided vehicles (AGVs) and industrial trucks. Instead, manufacturers are also relying on electric solutions here, which are better suited for mobile applications. However, for

efficient power supply and battery charging during operation, an appropriate charging infrastructure is needed in the factories first. Several leading automotive manufacturers are already using the innovative wireless charging technology from the PULS Business Unit Wiferion for charging AGVs and cobots. Wiferion’s contactless charging technology allows these vehicles to remain continuously in operation without disruptive charging breaks or manual interventions. Wireless charging offers significant advantages over conventional charging systems, such as the elimination of mechanical wear or the risk of tripping hazards from cables or contact strips. With Wiferion’s etaLINK and CW systems, AGVs and mobile robots can be efficiently and autonomously charged during their normal work cycle, such as during short stops at stations. The elimination of long downtimes for energy intake increases the fleet availability significantly. The energy transfer takes place directly via charging pads, which allow for high positioning tolerance and start the charging process in less than a second.
With the established 3 kW and the new 1 kW systems, Wiferion technology is currently leading in the market. The maintenance-free solutions enable a significant increase in fleet efficiency and operational safety – ideal for 24/7 continuous use in demanding environments such as the automotive and logistics industries.
