Siemens SITOP PSU400M 24 V/20 A Rail mounted PSU (DIN) 24 V DC 20 A 480 W 1 x

The compact DC/DC converter of the product line SITOP modular allows the DC link of frequency-controlled drive systems a low-cost power failure concept. The 20-A-switching power supply uses the kinetic energy of abbremsenden motors in order to buffer the 24-V supply for so long until the machine controlled shut down. For an extremely efficient handling of the power reserve ensures the high degree of efficiency. And because the available charging of capacitors voltage dependent, enables the wide input voltage range, a particularly high energy production. In addition to capacitors are also batteries as DC-source is well suited. The high overload capacity, functionality and robustness of the rail device allow it to be used in many applications, even under harsh conditions. The advantages at a glance:· Robust and compact design with only 90 mm width· 50% extra power" at the press of a button of loads with high power requirements· Built-in signalling contact "DC 24 V o.K."· 3 LED for different operating conditions· Adjustable start-up delay, e.g. for use in the DC link of frequency converters SINAMICS· Large temperature range from -25°C to +70°C· High shock and vibration resistance· Expandable by Supplemental modules redundancy module, selectivity module and DC-UPSThis text is machine translated....
