DESCRIPTION

–40 to +110°C

–40 to +32°C

The UHP-28.2/12-D48 is especially designed for

unattended cellular and PCS base stations, remote

wide band RF ampliﬁers and wireless communi-

cation facilities. To avoid unreliable system fans,

the UHP-28.2/12-D48 can be operated using con-

duction cooling while attached to a housing wall

or system heat sink. No forced airﬂow is needed

up to +110°C baseplate temperature.

UL/IEC/EN 60950-1

And CSA C22.2-No.234

MECHANICAL CHARACTERISTICS

With baseplate

2.30 x 2.40 x 0.502 inches (58.4 x 61.0 x 12.8 mm)

2.30 x 2.40 x 0.452 inches (58.4 x 61.0 x 11.5 mm)

Without baseplate

The UHP-28.2/12-D48's MTBF is 3 million hours

(+40°C GF) and ruggedization conforms to

ETSI 300-019-2-4. Multiple protection features

avoid damage to outside equipment and to the

converter itself. The converter will shut down on

sustained input undervoltage, output overcurrent,

output short circuit and overvoltage and thermal

shutdown. Overload currents less than a short

circuit limit the output current so that operation

is not interrupted. Upon short circuit shutdown,

the converter will automatically attempt to restart

(“hiccup” mode) when the overload is removed.

The input will tolerate up to 100V overvoltage

spikes (100msec).

The UHP-28.2/12-D48 uses industry-standard

half-brick external outline dimensions, pinout and

mechanical mounting. The overall unit is designed

to be as “lead-free” as practical in construction

and method of attachment (no lead added in

assembly).
