Description
The T Series converters are electrically isolated AC-DC
converters with an output power of up to 550 watts. For higher
power requirements several converters may be connected in
parallel.
The input is ideally adapted to the mains: Full power factor
correction, no inrush current, low RFI level, and high transient
and surge immunity are key design features. A T Series
converter behaves similar to a resistive load.
The LT models can be operated from a universal AC-input
range from 85 to 255 VAC. It is the preferred type for 230 VAC
mains, whereas the UT models are optimized for 110/
120 VAC mains. The output delivers an electrically isolated
Safety Extra Low Voltage (SELV) and is short-circuit and no-
load proof. Depending on the type, two output characteristics
are available, intended either for rectifier applications or for
battery charging purposes.
The latter types can be integrated into systems, where the
output voltage is backed-up by a battery. The float charge of the
battery can be set by a cell-voltage selector switch according to
the battery type used. These converters are equipped with a
temperature sensor input, in order to improve the life
expectancy of the battery.
The rectifier models are suited for DC-bus applications at
constant voltage. As the output voltage is SELV, even
electrically non-isolated switching regulators, such as the PSx
models, may be connected to the output.
The LT/UT1701 models are especially optimized to build
distributed power systems together with the 48Q or CQ Series
DC-DC converters, as the signalling capabilities of both families
are matched. Distributed power systems have as one
advantage less power losses over load lines and fewer
regulation problems.
Power-One also offers backplanes for fast and simple set-up
of 19" DIN-rack systems with T Series converters; see
Accessories.
