Description

The IMS25 Series of board-mountable 25 watt DC-DC converters has been designed according to the latest industry requirements and standards. The converters are particularly suitable for applications in industry and telecommunication where variable input voltages or high transient voltages are prevalent. Providing two wide input voltage ranges, to 36 VDC and to 75 VDC, the units are available with a single output voltage from 2.5 VDC to 16.5 VDC externally adjustable. A shut down input allows remote converter on/off. Features include efficient input and output filtering with unsurpassed transient and surge protection, low output ripple and noise, consistently high efficiency over the entire input voltage range, high reliability as well as excellent dynamic response to load and line changes. The converters provide basic insulation with SELV outputs as e.g., required in battery supported systems where the bus voltage may exceed the SELV limit of 60 VDC. They are designed and built according to the international safety standards IEC/EN UL 1950, CAN/ CSA C22.2 No.950-95. The circuit comprises integrated planar magnetics and all components are automatically assembled and soldered onto a single PCB without any wire connections. The proprietary magnetic feedback solution ensures maximum reliability and repeatability in the control loop over all operating conditions. 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 to an ambient temperature °C in free air without using any potting material. For extremely high vibration environments the case has holes for screw mounting.

Examples: 48 IMS 25-12-9Z: DC-DC converter, input voltage range 75 V, output A, no case. 24 IMS 25-2.5-9G: DC-DC converter, input voltage range 36 V, output 6 A.

The IMS25 Series of DC-DC converters are magnetic feedback controlled forward converters using current mode PWM (Pulse Width Modulation). The 2.5, 3.3, and 5.1 V output voltage versions feature a synchronous rectifier resulting in very high efficiency. The output voltage of these versions can be adjusted via the Trim input. The Trim input is referenced to the secondary side and allows for programming of the output voltage in the range of approximately V o nom using an external resistor. The voltage regulation is achieved with a magnetic feedback circuit providing excellent line and load regulation. Current limitation is provided by the primary circuit, thus limiting the total output current to approx. 150%· Io nom (see: Type Survey). The shut down input allows remote converter on/off. Overtemperature protection will shut down the unit in excessive overload conditions with automatic restart.

General conditions: = 25°C, unless TC is specified. ­ Shut down pin left open circuit (not connected). ­ Trim input not connected. Table 2: Input Data
