Summary

The latter types can be integrated into systems where the

output voltage is backed-up by batteries. The float charge

of the battery can be set by a cell voltage selector switch

according to the battery type used. Moreover these units

feature a temperature sensor input to improve the life ex-

pectancy of the battery.

The T series of converters are electrically isolated AC-DC

converters with an output power of up to 550 Watt. For

higher power requirements several units may be connected

in parallel.

The input of the T units 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.

The T units behave similar to a resistive load.

The rectifier types suit for DC-bus applications at constant

voltage. As the output voltage is SELV, even electrically non

isolated switching regulators such as the PSR types may

be connected to the T output.

The L-input provides a universal AC-input range from

85...255 V AC. It is the preferred type for 230 V mains,

whereas the U-input range is optimized for 110/120 V

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 T 1701 types are especially optimized to build distrib-

uted power systems together with the CQ-series DC-DC

converters as the signalling capabilities of both families are

matched. Distributed power systems have as one advan-

tage less power loss over load lines and fewer regulation

problems.

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

up of 19" rack systems with T units (see chapter: Back

Planes).
