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.

Description

The T Series converters are electrically isolated AC-DC

converters with an output power of up to 550 W. For higher

power requirements several converters may be connected in

parallel.

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 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/UT1701 models are especially optimized to build

distributed power systems together with the 48Q, CQ, or CP

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.

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.

Power-One also offers backplanes for fast and simple set-up

of 19" DIN-rack systems with T Series converters; see

Accessories.

The latter types can be integrated into systems, where the
