Benefits
|
SITOP smart are the universal and powerful standard power supplies for mechanical and plant engineering.Despite their compact design they offer excellent overload behavior. Thanks to a power boost of 150% loads with high power consumption can be connected without any problems and the permanent overload capability of 120% offers power reserves in case of expansions.The high degree of efficiency results in low energy consumption and minimal heat generation inside the control cabinet.To further increase 24 V availability; the SITOP smart power supplies can be combined with buffer; DC-UPS; redundancy and selectivity modulesSingle-phase and three-phase standard applications up to 40 ACompact design; no lateral clearances requiredExtra power with 1.5 times the rated current (5 s/min) for brief operational overloadsPermanent overload capability with 1.2 times the rated current up to 45 °C ambient temperatureAdjustable output voltage for compensating voltage dropsParallel switching option to increase performanceHigh degree of efficiency up to 91.5%Wide temperature range from -25 °C or 0 °C to +70 °CComprehensive certification such as cULus; cCSAus; ATEX; IECEx and GL
