SMP21-L20-DC24V-10A Datasheet, PDF (1/6 Pages) ETAL Group – The devices switches over automatically when connected to AC 115 V AC and 230 V

Switched mode power supply for DIN rail mounting type SMP21 DC24V/10A
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
l The devices switches over automatically when connected to
AC 115 V AC and 230 V
l 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
l Efficiency up to 89 %
l Integral passive power factor compensation
l Parallel mode for performance improvement (selectable by switch)
