● Do not modify, disassemble, or open this product. Failure to do
so can cause electric shock hazard. TDK-Lambda cannot be
held responsible for damage caused by modifications to this
product.
● Internal voltage can be retained inside the product. Do not touch
any parts inside the product be-cause there can be high-voltage
and high-temperature parts even when the electric current is not
applied. This can cause an electric shock hazard or burn injury.
● There can be high-voltage and high-temperature parts even in
products without a cover. Do not touch them. Touching them can
cause an electric shock hazard or burn injury.
● While electric current is being applied, keep your hands and face
away from it. This may cause in-jury or an unexpected accident.
● Be sure to read the catalogue and instruction manual before
using this product. For strictly ac-curate information, request
the specifications of the delivered product to check the more
detailed information. Incorrect usage could lead to an electric
shock, damage to the product or a fire hazard.
● If there are di erences between the specific information given
for your product and this document, the specific information
given for your product has priority.
● Use this product within the specified input voltage, output
power, output voltage, output current, and range of ambient
temperature/ambient humidity. Using this product in conditions
beyond the specification limits can shorten the lifetime of the
product, or can cause, damage to the product, electric shock, or
a fire hazard. Also, measure the temperature inside the device
to check that there are no problems.
● Check the direction the product should face and the conditions
for ventilation in the specifications of the delivered product, and
use the product in the correct manner.
● Disconnect the power input before connecting inputs and
outputs.
● If an internal fuse becomes burned out, do not use the unit by
replacing the fuse. This can cause trouble inside the unit. Be
sure to request us to repair the unit.
● Insert fuses in the input circuit for products in which protection
circuits (elements, fuses, etc.) are not installed, to prevent
smoking or burning. Also for products with protection circuits
installed inside, an appropriate use of protection circuits is
recommended as there is possibility that the in-ternal protection
circuit may not operate depending on the usage conditions.
Usage Precautions
● Use only the fuses specified or recommended by TDK-Lambda
for external fuses.
● This product is designed and manufactured as a component part
to be installed in electronic de-vices. Attach the warning label to
the unit and insert the notes in the instruction manual.
● Malfunction and failure may be caused if this product is used in
a strong electromagnetic field.
● Failure may be caused in the power supply unit due to corrosion
if used in environments with corrosive gas (hydrogen sulfide,
sulfur dioxide, etc.).
● Malfunction and failure may be caused if this product is used in
environments with conductive sub-stances or dust.
● Be sure to take protective measures against the surge voltage
caused by lightning, etc. Damage to the unit may be caused due
to irregular voltage.
● Connect the frame ground terminal of the power supply unit to
the earth terminal of the device, for safety and to reduce noise.
If grounding is not made, it may cause an electric shock hazard.
● It is necessary to exchange consumable parts (built-in fan,
electrolytic capacitor) periodically. Set an appropriate overhaul
interval period for the performance of maintenance. There
may be some cases where overhaul maintenance cannot be
conducted due to unavailability of parts due to pro-duction
discontinuation.
● This product might fail accidentally or through unexpected
conditions. When using this product with application devices, in
which an extremely high reliability is required (Nuclear-related
devices, tra c control devices, medical devices, etc.), be sure to
ensure that the fail-safe function is e ec-tive in the devices.
● As for EMI or immunity, they are measured in the TDK-Lambda
standard conditions. It is not guaranteed that this product meets
industry standards or regulations when being used in dif-ferent
conditions of mounting and wiring. Assess and evaluate values
on the actual device before use.
● To export this product, follow the necessary procedures of
application for the export license by the government of Japan,
etc., complying with the regulations of the Foreign Exchange
and Foreign Trade Control Law.
● The information in this catalogue is subject to change without
prior notice.
