SITOP Modular: SITOP PSU400M 24 V/20 A - Efficient DC/DC converter for drive and battery systems

Catalog excerpts

SITOP PSU400M 24 V/20 A Efficient DC/DC converter for drive and battery systems August 2011 The compact DC/DC converter enables a costeffective network failure concept at the DC link of frequency-controlled drive systems. The 20 A switching power supply uses the kinetic energy of decelerating motors to buffer the 24 V supply until the machine has completed a controlled shutdown. Its high efficiency ensures an extremely effective use of the energy reserve. And because the available charge of capacitors is voltage-dependent, the wide input voltage range enables particularly high energy generation. In addition to capacitors, batteries are ideally suited as a DC source. The high degree of overload capability, functionality, and robustness of the DIN rail device permit its use in many applications, even under harsh conditions. Wide-range input for 200 to 900 V DC High energy generation from capacitors High degree of efficiency up to 96% Robust and compact design with only 90 mm width 50% "extra power" for connection of loads with high current demand Integrated signaling contact "24 V DC OK" 3 LEDs for different operating states Adjustable startup delay, e.g. for operation at the DC link of SINAMICS frequency converters Wide temperature range from -25 to +70 °C High shock and vibration resistance Expandable with the following add-on modules: redundancy module, selectivity module and DC UPS SITOP modular Answers for industry.

effective power failure concept also saves time and money in printing and paper machines, textile machines, high-bay warehouses, and cranes. In applications without significant kinetic energy, the buffer time can be extended by means of additional capacitors at the DC link, e.g. for pure actuators. A wide input range opens up many possibilities The wide DC input range of the SITOP PSU400M also permits the connection to many different DC networks and battery systems. It provides a special advantage if capacitor batteries are used. Because the capacitor charge is disproportionately dependent...
