ESCRIPTION
The most outstanding features of this Dimension QS40.361 DIN rail
power supply are the extremely high efficiency and the small size,
which are achieved by a synchronous rectification, a bridgeless PFC
circuit and additional unique design details.
Large power reserves of 150% and built-in large sized output
capacitors support the starting of heavy loads such as DC motors or
capacitive loads. In many cases this allows the use of a unit from a
lower wattage class which saves space and money.
High immunity to transients and power surges as well as low
electromagnetic
emissions
environment possible.
The integrated input fuse as well as the near zero input inrush
current make installation and usage simple. Diagnostics are easy
due to the DC-OK relay, a green DC-OK LED and the red overload
LED.
A large international approval package for a variety of applications
makes this unit suitable for nearly every application.
