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).
