Description
The T Series converters are electrically isolated AC-DC con-
verters with an output power of up to 550 W. 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 con-
verter 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, CQ, or CP
Series DC-DC converters, as the signaling capabilities of both
families are matched. Distributed power systems have as one
advantage less power losses over load lines and fewer
regulation problems.
Bel Power Solutions also offers backplanes for fast and simple
set-up of 19" DIN-rack systems with T Series converters; see
Accessories.
