The LX350 series offers 350 Watts of continuous output power in a low profile
industry standard footprint. With two standard single output options and a
flexible standard multiple output version, the series can address most
requirements as standard. The design is specifically tailored to allow full
flexibility and modifications to meet customer applications can be implemented
with relative ease. The LX350 AC input series meets the safety requirements of
EN60950, VDE0805, UL1950 and CSA 22.2 No. 950. Input conducted noise
levels meet the requirements of EN55022 class B. LX350 series power supplies
are ideal for use in applications such as point-of-sale equipment, central and
public telecom power systems and network equipment.

Notes
1
The multiple output LX350 has a continuous output power rating of 350W.
The single-output versions have a continuous output power rating of
385W.
Peak power figures for individual outputs on the multiple output unit are
for less than 10 seconds duration. The overall peak power for the unit is
550W for 10 seconds duration.
Single output models are adjustable -8%, +16%.
A 10% load on the main output is necessary to maintain regulation on the
auxiliaries at full load (multi output model).
The input board is fitted with an autorange circuit as standard which
automatically senses the input voltage and switches to the appropriate
voltage range.
This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
Consideration should be given to measuring the temperature on the main
transformer (T1) when the power supply is installed in end-use equipment.
The measured temperature on T1 must not exceed 90
°
C. For further
information on the LX350 safety approvals, contact Computer Products.

OVERLOAD/SHORT CIRCUIT PROTECTION
The overload/short circuit protection mechanisms are different for the single
output models and the multiple output model.
The single output models will current limit when the output load reaches
105-120% of maximum load during overload or short circuit conditions.
The unit will operate in a constant current mode making the single output
models suitable for battery charging applications.
The multiple output model uses a power limiting function. When the total
output power reaches 600W the outputs will foldback to the values detailed
below:
Foldback Value
Output
+5V
30A continuous
+12V
8A continuous
+24V
4A continuous
–5V/–12V
Protected by 4A Multi Fuse™
The outputs will not foldback until the total output power exceeds the maxi-
mum power limits. This allows the units to have a peak power capability
but it requires that care must be taken not to permanently overload any
individual output. The +5V, +12V and +24V outputs are not individually pro-
tected and it is recommended that the maximum continuous load does not
exceed the value given in the output specifications. The -5V and -12V out-
puts are individually protected by a 4A Multi Fuse™ and the maximum con-
tinuous load should not exceed the value given in the output specifications.
SIGNALS (OPTIONAL)
An optional signals board supplies the following VME utility bus signals:
ACF (AC Fail) Logic 1 to 0 transition occurs >10ms before outputs fall
below 80%-85% of nominal in the event of input failure.
DCF (DC Fail) Logic 0 occurs if output falls below <85%–95% of nominal.
SRS (System Reset) Logic 1 for system OK (AC and DC good and reset
times [200ms])
PM Power Monitor signal, proportional to the output power, ratio of
10mV/W,
±10%.
PS Power Share connections, to be joined for parallel operation of two
or more units, ensuring equal power share. For power share
operation unit outputs need to be set to ±5% of each other and
should be connected in star configurations with the load as star
centre.
