DIN rail power supplies

PLANET is a new generation of industrial power supplie. The single- and three-phase DIN rail power supplies were developed for demanding industrial applications and set new standards in energy efficiency, service life and ease of use.

PLANET is, says PULS, the first DIN rail power supply to feature active load sharing in parallel operation. Thanks to this technology, high-power systems can be realised more quickly using fanless power supplies. The precise control balances the load between power supplies, ensuring even thermal distribution and thus optimal system reliability.

The family currently includes single-phase and three-phase models with 960W. An efficiency level of 97% reduces energy losses and heat generation, lowers operating costs, and contributes to CO₂ reduction. The reduced heat generation makes the compact design of a three-phase 960 W unit with a width of just 79mm possible, creating more space in the control cabinet.

For applications with dynamic loads – such as motor control in intralogistics and robotics – the devices offer Dynamic BonusPower, which automatically adapts to the changing demands of the application. With this technology, the three-phase TP960 can provide power reserves between 120% (continuous) and 200% (12 seconds), depending on the duration. This enables reliable handling of acceleration processes without the need to use oversized power supplies.

With an MTBF of up to 325,000 hours and a minimum service life of 100,000 hours, the new power supplies are designed for long-term operation. The sophisticated convection-cooled design supports reliable continuous operation without a fan. The optimised Hiccup^Plus protection mechanism increases system safety in the event of overload or short circuit.
