IMS 6 Series
Summary
The IMS 6 series of board mountable 6 W DC-DC converters has been designed according to the latest industry requirements and standards. The converters are particularly suitable for use in mobile or stationary applications in transport, industry or telecommunications where variable input voltages or high transient voltages are prevalent. Covering a total input voltage range from 18 V DC up to 75 V DC. The converters are designed and built according to the international safety standards IEC/EN 60950, UL 1950, CAN/CSA C22.2 No.950-95 and are LGA and UL marked.
A special feature is their small case size, DIL 24 with only 9.0 mm profile. The circuit comprises integrated planar magnetics and all components are automatically assembled and solidly soldered onto a single PCB without any wire connections. Thanks to the rigid mechanical design the units withstand an extremely high level of shock and vibrations. Careful considerations of possible thermal stresses ensure the absence of hot spots providing long life in environments where temperature cycles are a reality. The thermal design allows operation at full load up to an ambient temperature of 71 C in free air without using any potting material. Options : SMD pinout or K-pinout, an alternative to the standard industrial pinout, provide a high level of application specific engineering and design-in flexibility.

Functional Description
The IMS 6 DC-DC modules are feedback controlled flyback converters using current mode PWM (Pulse Width Modulation). The converter input is protected against transients by means of a suppressor diode. The output voltage is monitored by a separate transformer winding close to the secondary windings and fed back to the control circuit.

Current limitation is provided by the primary circuit, thus limiting the total output current (Io nom for the single and Io1 nom + Io2 nom for the dual output types). The close magnetic coupling provided by the planar construction ensures very good regulation and allows for flexible load distribution on dual output types.

Thermal Considerations
DC/DC Converters < 40W
Output overvoltage protection
IMS6 Series
If a converter, mounted on a PCB, is located in free, quasistationary air (convection cooling) at the indicated maximum ambient temperature TA max (see table: Temperature specifications) and is operated at its nominal input voltage and output power, the case temperature TC measured at the: Measuring point of case temperature TC (see: Mechanical Data) will approach the indicated value TC max after the warm-up phase. However, the relationship between TA and TC depends heavily on the conditions of operation and integration into a system. The thermal conditions are influenced by input voltage, output current, airflow, temperature of surrounding components and surfaces and the properties of the printed circuit board. TA max is therefore only an indicative value and under practical operating conditions, the ambient temperature TA may be higher or lower than this value. Caution: The case temperature TC measured at the Measuring point of case temperature TC (see: Mechanical Data) may under no circumstances exceed the specified maximum value. The installer must ensure that under all operating conditions TC remains within the limits stated in the table Temperature specifications. Short Circuit Behaviour The current limit characteristic shuts down the converter whenever a short circuit is applied to its output. It acts selfprotecting and automatically recovers after removal of the overload condition. Typical Performance Curves

The outputs of the IMS 6 converters are protected against overvoltages by Zener diodes. In the event of an overvoltage on the output, the unit will shut-down and attempt to restart automatically. The main purpose of this feature is to protect against possible overvoltages which could occur due to a failure in the feedback control circuit. The units are not designed to withstand external overvoltages applied to the outputs. Connection in series The outputs of single or dual output units can be connected in series without any precautions, taking into consideration that the highest output voltage should remain below 60 V for SELV operation. Connection in parallel The outputs of several units with equal nominal output voltage can be connected in parallel. Approximate current sharing between 2 or several units is ensured by their load dependent output characteristic.

Input Fuse To prevent excessive current flowing through the input supply line in case of a short-circuit across the converter input an external fuse should be installed in a non earthed input supply line. We recommend a fast acting fuse F0.5A for 24 IMS 6 and F0.315A for 48 IMS 6 types. Standards and approvals All DC-DC converters are UL recognized according to UL 1950, UL recognized for Canada to CAN/CSA C22.2 No. 950-95 and LGA approved to IEC/EN 60950 standards. The units have been evaluated for: * Building in * Supplementary insulation input to output, based on their maximum input voltage * The use in a pollution degree 2 environment * Connecting the input to a secondary circuit which is subject to a maximum transient rating of 1500 V. Safety of operator accessible output circuits If the output circuit of a DC-DC converter is operator accessible, it shall be an SELV circuit according to IEC/EN 60950 related safety standards The insulation concept table below shows some possible installation configurations, compliance with which causes the output circuit of the DC-DC converter to be an SELV circuit according to IEC/EN 60950 up to a configured output voltage (sum of nominal voltages if in series or +/- configuration) of 46 V. However, it is the sole responsibility of the installer to ensure the compliance with the relevant and applicable safety regulations. More information is given in: Technical Information: Safety.
The DC-DC converters are subject to manufacturing surveillance in accordance with the above mentioned UL, CSA, EN and ISO 9001 standards.

The front end output voltage should match the specified input voltage range of the DC-DC converter. The earth connection has to be provided by the installer according to the relevant safety standard, e.g. IEC/EN 60950. The installer shall provide an approved fuse (type with the lowest rating suitable for the application) in a non-earthed input line directly at the input of the DC-DC converter (see fig.: Schematic safety concept). For UL's purpose, the fuse needs to be UL-listed. See also: Input Fuse. Each suppressor diode should be dimensioned in such a way, that in the case of an insulation fault the diode is able to limit the output voltage to SELV (<60 V) until the input fuse blows (see fig.: Schematic safety concept). Has to be insulated from earth by double or reinforced insulation according to the relevant safety standard, based on the maximum output voltage from the front end.
