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 W. 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 Melcher 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 Melcher CQ-series

DC-DC converters as the signalling capabilities of both

families are matched. Distributed power systems have as

one advantage less power loss over load lines and fewer

regulation problems.

Melcher offers also backplanes for fast and simple set-up of

19" rack systems with T units (see chapter: Back Planes).
