Furthermore, the SDR-75 offers 9 to 12.5% greater efficiency than comparable models, and its operating temperature range of -30°C to 70°C is higher than the -10°C to +60°C range of the DR-75, reflecting the growing trend toward energy conservation.
Featuring an updated high-performance circuit, the SDR-75 series boasts a full-range AC input (88-264 Vac) and up to 90% efficiency, allowing for free air convection cooling from -30°C to 55°C or 60°C ambient temperature under full load conditions, and even up to 70°C with reduced power consumption. The SDR-75 supports a maximum load of up to 150% of its capacity and comes equipped with constant current overload protection that limits and delays shutdown, adapting to all types of critical loads, such as inductive and capacitive loads. Other standard features include a front panel LED indicator, front-panel DC voltage adjustment, and protection against overload, short circuit (constant current mode), overvoltage, and overtemperature. They are UL, CUL, CB, and TUV listed, CE certified, and meet the EMC immunity requirements for heavy industry (EN61000-6-2). Common applications include industrial control systems, semiconductor manufacturing equipment, factory automation, electromechanical applications, and any installation requiring fanless or low-noise equipment.
