Switched mode power supply for DIN rail mounting type SMP21 DC24V/5A
Description
Switched mode power supply for rail mounting, with independent
change-over of input voltages (AC 115/230 V), integral passive power
factor compensation (PFC), high power reserve and optional parallel
mode.
Features and Benefits
lꢀ ꢀThe devices switches over automatically when connected to
AC 115 V AC and 230 V
lꢀ ꢀWide range inputs from AC 90 to 132 V at rated input voltage 115 V,
and AC 180 to 264 V at rated input voltage 230 V
lꢀ Efficiency up to 86%
lꢀ Integral passive power factor compensation
lꢀ Parallel mode for performance improvement (selectable by switch)
