The board-mount product line-up comprises four power levels, 5, 10, 15 and 25W, and is housed in three compact package sizes. The 5W and 10W units measure 38.1×25.4×21.5mm, the 15W 50.8×25.4x24mm and the 25W models 63.5×25.4x 29mm. Four popular output voltages are available, 5V, 12V, 15V and 24V, and all operate from a wide range input voltage of 85-265VAC, 47-440Hz.
The KWS-A can start up at -40°C and operate without forced air cooling in ambient temperatures of up to 85°C, and at full load over a -10 to +55°C range (45°C for the 5V output 10W to 25W models). Off-load power draw is less than 0.5W and full load efficiencies are as high as 88%. Board design is made simpler and space minimised as no external fusing or electrolytic capacitors are required.
The series carries certification to UL/CSA/IEC/EN 60950-1 and the CE mark for the Low Voltage and RoHS2 Directives. All models comply with EN 55011-A conducted and radiated emissions (class B with the addition of a small X-capacitor) and EN 61000-4-2, -6-2 immunity standards.
