The sources of the NDR-240 series are industrial sources on a DIN rail with a metal chassis. This model provides 24 V DC output voltage, adjustable from 24 to 28 V , with a maximum current of 10 A and power of 240 W . It is mounted on a DIN rail, where it occupies 63 mm in width. The source is prepared for a wide range of input voltages from 90 to 264 V AC and meets the European standard EN 61000-3-2. The outer shell is made of metal material, which ensures strength and robustness. With an efficiency of up to 88.5% , the source is able to work in a temperature range of -20 to 70 °C. Thanks to the supply of constant current and overload protection, it is widely used in both domestic and industrial installations.
