Power supplies of the LRS-N2 series with increased peak current from MEAN WELL

05.02.2024

Closed-type power supplies are widely used in various industries, including for electrical equipment with high starting currents. MEAN WELL has developed power supplies of the LRS-N2 series that provide short-term peak power of 200%, which makes them particularly suitable for use in systems where the load can change quickly and unexpectedly, such as power and motor control systems or industrial control systems.

The power supplies of the LRS-N2 series are AC/DC converters in a case design, with an output voltage of the standard range – 12, 24, 36, 48V DC, rated power of 100, 200, 350 and 600W. A distinctive feature of the N2 modification is the increased output power – up to 200% of the rated power for use with loads with high starting currents. The dimensions of the case are the same as in the LRS series, which makes them interchangeable.

The power supplies of the LRS-N2 series have a built-in output current limiting circuit (constant current limiting circuit) with a current limitation level of 200% for 5 seconds, the main types of protection: short circuit, overload, overvoltage (all models), overheating (except LRS-100N2). The power supplies of the LRS-100N2, LRS-200N2 series are cooled by natural ventilation, and the LRS-350N2, LRS-600N2 units use forced ventilation due to an integrated cooling fan with intelligent control. All power supplies of the LRS-N2 series have a warranty period of 3 years.

The calculation of the permissible output power for the LRS-N2 power supply is carried out from the following ratios: Расчет допустимой выходной мощностиCalculation of the permissible output power for the LRS-N2 series

Examples of calculating the permissible output power are given in the Specifications, which allows for an adequate calculation and selection of a suitable model depending on the load parameters.

The power supplies of the LRS-N2 series are designed primarily for use with loads with high starting currents – electric motors and electromechanical devices. They can be used as general-purpose AC/DC converters in various industries, including production automation, process control, medical equipment, telecommunications equipment, etc.
