Robust and ultra-compact metal housing for harsh industrial environments. The high efficiency of up to 92% allows the power supplies to operate in a temperature range of -25 °C to +70 °C. The model is protected against short circuits, overloads, and overheating, and has been tested for shock and vibration. The constant current characteristic and power boost enable the smooth startup of heavy loads or the charging of batteries. In addition to ATEX certification, the following safety standards are met: IEC/EN 60950, UL508, EN60204, EN50178, and EN61558-2-4.
