ZWX Series
Fanless multiple output power supplies
- ideal for industrial equipment
ZWX Series
Easy to use and highly reliable
The use of fans in traditional ATX power supplies
restricts system layout and necessitates the use
of forced air cooling. The ZWX design guaran-
tees both operation and performance for
increased flexibility and reliability.
The low profile, open frame format' is able to be
mounted in 1U racks, a desired feature for
industrial equipment. In addition, two further
options will be available in April 2008 - a "L
bracket" and an "enclosed" type bringing further
flexibility to the equipment design.
Further flexibility is provided with guaranteed operation
at zero load on any output. Many ATX power supplies
require a minimum load on the main outputs, restricting
operation and wasting power. Output power can be
drawn from a combination of outputs (Wattbox
format) provided the overall ratings are not
exceeded. This feature allows designers to utilize the
power of the ZWX series and produce a low
acoustical noise design.
The use of pcb mount connectors on the power
supply rather than a fixed cable harness allows the
output wiring to be tailored to the system design.
High reliability is demanded by industrial equipment
manufacturers and the power supply is critical to the
longevity of the overall equipment. Densei-Lambda, the
World's No.1 power supply provider for industrial
equipment, now offers an alternative to the traditional
general purpose ATX power supply.
Product line-up
The ZWX Series can be used in ambient
temperatures from -10°C to + 70°C with opera-
tion at 100% load from -10C to 50C. This specifi-
cation is unique to the World's No.1 provider of
industrial power supplies.
Fanless open frame Multiple Output Power Supplies
A new format of highly reliable ATX power supplies
Gives you more design freedom
Fanless power supplies makes
you free from constraint.
Wide operating temperature for
industrial equipment.
Low 36mm profile for mounting
in a 1U rack.
A 10% efficiency improvement has been obtained
compared to existing products like Lambda's
ZWQ series. An 84% efficiency rating is achieved
by our unique circuit technology (patent pending).
This high efficiency rating enables convection
cooling in a low profile package.
High efficiency - the proof of
technology.

ZWX Series Instruction Manual
Be sure to read this instruction manual thoroughly before using
this product.
Pay attention to all cautions and warnings before using this product.
Incorrect usage could lead to an electric shock, damage to the unit
or a fire hazard.
Never use this product in locations where flammable gas or ignit-
able substances are present. When a spark is generated, there are
risks of igniting these substances and exploding.
● This product is primarily designed and manufactured as Class 1
equipment. In the interest of safety, connect to earth before
using the product.
● Do not touch this product and the internal components in oper-
ation or shortly after shut down. They may have high voltage or
high temperature and as the product dissipates its heat so the
surface of the product is hot. You may receive electric shock or
burn.
● When this product is operating, keep your hands and face away
from it as you may be injured by flying debris in the event of a
fault.
● Do not make unauthorized changes to this product, otherwise
you may receive electric shock and void your warranty.
● Do not drop or insert anything into this product. It might lead to
a failure, fire and/or electric shock.
● Do not operate this product after it falls down.
● Do not use this product in the event of the emission of smoke or
abnormal smell and sound etc. It might lead to fire and/or elec-
tric shock. In such cases, please contact us. Do not attempt to
repair by yourself, as it is dangerous for the user.
● Do not operate this product in the presence of condensation. It
might lead to fire and/or electric shock.
● This power supply is designed for use within an end product.
● Confirm connections to input/output terminals and signal ter-
minals are correct as indicated in the instruction manual before
switching on.
● Input voltage, output current, output power, ambient tempera-
ture and ambient humidity should be kept within specifications,
otherwise the product will be damaged.
● Do not operate and store this product in an environment where
condensation might occur. In such case, waterproof treatment
is necessary.
● Do not use this product in environment with a strong electro-
magnetic field, corrosive gas or conductive substances.
● For applications which require very high reliability (nuclear re-
lated equipment, traffic control equipment, medical equipment,
etc.), it is necessary to provide a fail-safe mechanism in the end
equipment.
● Do not inject abnormal voltages into the output or signal of this
product. The injection of reverse voltage or over voltage ex-
ceeding nominal output voltage into the output or signal termi-
nals might cause damage to internal components.
● Never operate the product under over current or short-circuit
conditions for more than 30 seconds, or outside its specified In-
put Voltage Range. Insulation failure, smoking, burning or other
damage may occur.
● This product contains a printed circuit board utilizing surface
mounted devices. PCB stress such as bending, twisting etc.
could cause damage. Therefore, please handle with care.
● When handling this product, hold the board edge and take not
to touch the component side. When installing this product in
apparatus or equipment, mount it on spacers.
● The output of this product is considered to be a hazardous
energy level. (The voltage is 2V or more and the power is 240VA
or more.) It must not be made accessible to users. Protection
must be provided for service engineers against indirect contact
with the output terminals and/or to prevent tools being dropped
across them. While working on this product, the AC input power
must be switched off and the input and output voltage should
be zero.
● When using for personal computer (hereinafter called PC), cut
input voltage with you may stop PC. When the AC switch is cut
while PC is operating, PC might be damaged. Especially, when
the AC switch is cut while the memory such as hard disks is
operating, you may damage data in a PC.
● This product has used Power Thermistor to protect the circuit
from Inrush Current. Frequent repetition of input might cause
damage to internal components because of generating surge cur-
rent.
● Breaking of internal fuse is considered internal failure. In such
cases, please contact us.
● The information in this document is subject to change without
prior notice. Please refer to the latest version of the data sheet,
etc., for the most up-to-date specifications of the product.
