Dc dc converters - Import export

The DC-voltage converters developed for the electronic components in the motor car are characterised by their ease of installation in every vehicle. The high degree of stability, the compact design, sustained short-circuit resistance as well as the high level of operating safety are the quality hallmarks of this series. The areas of application span the mobile employment of 12-V-consumers in vehicles with a 24-V-onboard network. The devices are particularly suitable for operating car radios, stereo units, radios, cooler units, car telephones, computers, 12-V-trailer lighting etc. The voltage converter converts an input direct voltage into an output direct voltage. The input voltage must be greater than the output voltage. No base load is required at the output end. A 26 kHz PWM switching controller is used for this purpose. Input and output are not isolated. The common earth is connected with the voltage converter housing.

The amplifier module model 9243 is used wherever measurement signals from strain gauges, potentiometric sensors or DC/DC sensors have to be converted into standard signals. Simply by mounting on conventional DIN-mount rails, it is possible to position the amplifier module on location, in the proximity of the sensor. Especially for rough environments a IP65 version is available. The broad auxiliary power range and the choice between AC or DC permits operation on standard power supplies used in switch gear cabinets. A highly precise reference voltage source is built-in for calibration purposes. A calibrating shunt can also be connected via two separate terminals. This permits deliberate detuning of a strain gauge sensor for calibration or merely to check the measuring chain.

✓ Ultra wide input range 6...36VDC ✓ Selectable output voltage +12V, +19V or +24V ✓ Very compact design 132mm x 56mm x 17mm ✓ Full performance in the extended temperature range of -20°...+60°C ✓ Very high efficiency up to 98% ✓ More than 10 years capacitor lifetime ✓ Optional output voltage compensation via sense lines ✓ Optional Remote On/Off ✓ Incl. thermal pad, jumper and distance bolts ✓ Made in Germany With 98% efficiency and 300W output power the powerful open frame DC/DC converter offers an ultra-wide 6-36 V input as well as three selectable output voltages 12V / 19V / 24 V, so that almost any corresponding single-voltage motherboard or computer system can be supplied. The very compact DC converter “Made in Germany” delivers fanless full power in the extended temperature range of -20°…+60°C and up to an operating altitude of 5000m.

Thanks to the intelligent combination of DC fans with a fully integrated AC/DC converter, AC fans can now be operated at speeds that are independent of the power frequency. Up to 4500 rpm can be realized and the flow rate significantly increased if required. The EC generation in the dimensions 80mm to 280mm and with several different speeds replaces the previous AC fans in situtations where there is no DC voltage available and requires less power in the process. The previous AC fans can be replaced without restriction as the EC fans have identical dimensions and thickness. The versions that are smaller than 180mm have a wide-range input and can be connected without problem, worldwide to all AC voltage networks without need for further adaptation. This is underlined by the UL approval of the entire fan series.
