DC/DC-Wandler 80 W
DC/DC Converter 80 W
Caution: Danger of Electric Shock
When operating the DC/DC converter, certain components of the device are dangerously energised. Therefore, it is mandatory to de-
energise the converter and protect it against switch-on before working with the converter. If these procedures are disregarded, touching
the electrical parts could result in death or serious injury.
Operating Hints and Installation
The installation of the power supply has to be executed by qualified personnel only and under consideration of the latest country-specific
standards and regulations.
The DC/DC converter is a built-in device and thus shall only be operated in a protecting cover which ensures the requirements as regards
touch protection and fire safety. The converter's input and output have to be connected via the prescribed connectors. Connecting and
disconnecting of the converter may only be done while de-energised. The DC/DC converter has to be mounted with 4 M5 screws. The
device has to be switched-off via a suitable means outside of the power supply. The DC/DC converter is maintenance-free and does not
contain any user serviceable components. The user has to respect the technical data and prescribed ambient temperatures.
Caution: Burn Hazard!
Depending on the ambient temperature and load condition of the converter, the case temperature can be very hot, even after being set
to switch-off mode!
Fuse Protection
Due the complete encapsulation, the converter does not contain an internal fuse. Therefore, the prescribed fuses are mandatory for
device and line safety. Only fuses or circuit breakers respectively rated for DC current are allowed.
Primary and secondary connections
For connecting the converter, only the prescribed counterplugs shall be used. The counterplugs have to be protected against unintended
loosening by tightening the intergrated screws. The counterplugs have to be coded acc. to the specification in order to prevent the
exchange of the base plate and heat sink version in case of service.
Cooling
Version WK / WK-VT: The device has to be installed in a way that ensures free convection; the integrated heat sink should preferably be
mounted vertical. If the heat sink is installed in another way as described, the output power has to be reduced depending on the ambient
conditions. The max. heat sink temperature of 90 °C (measured at the heat sink base plate) shall not be exceeded.
Version W / W-VT: The converter has to be mounted on a heat-dissipating surface. The mentioned temperature at reference point at the
base plate shall not be exceeded and the mentioned necessary thermic resistance of the heat-dissipating surface has to be considered
resp.; see data sheet.
EMC
The converter has to be integrated into the EMC concept of the whole system via functional ground.
The functional ground can be connected on the determinated fastening point.
Fire Protection acc. EN 45 545-2
There are two options of classifying the DC/DC converter acc. to EN 45 545-2: small electrical component R26 (EL10) or grouped materi-
al R24. The end user has to decide which classification applies in his application.
High Voltage Tests for Isolation
MTM Power provides fully tested components. Among these, a high-voltage test is performed with the documented isolation test voltage
(factory test) for each power supply unit at the end of the manufacturing process. A re-performance of this test is not permitted but with
reduced test values. MTM Power is not liable for damage caused by disregarding these rules.
