BCD20006-G Rev AC, 06-Jul-2012 Page 3 of 12 www.power-one.com Functional Description The IMX4 Series converters are feedback-controlled flyback converters using current mode PWM (Pulse Width Modulation). The 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 (I o nom for single- and the sum Io1 nom + Io2 nom for dual-output models). The close magnetic coupling provided by the planar construction ensures very good regulation and allows for flexible load distribution on dual-output models.

BCD20006-G Rev AC, 06-Jul-2012 Page 5 of 12 www.power-one.com Input Transient Voltage Protection In many applications transient voltages on the converter input are always possible. These may be caused for example by short circuits between Vi+ and Vi–, where the network inductance may generate high energy pulses. In order to protect the converter, a transient voltage suppressor diode is fitted to the input; see table below. Table 4: Built-in transient voltage suppressor Model Breakdown Peak power Peak pulse voltage at 1 ms current VBR nom P P IPP 5IMX4 -- -- -- 20IMX4 40 V 600 W 10.3 A 40IMX4 100 V 600 W 4.1 A 70IMX4 150 V 600 W 2.9 A Fig. 8 External circuitry to comply with IEC/EN 61000-4-5, level 2. Vi+ Vi– Ci Li D 04036b If transients generating currents above the peak pulse current IPP are possible, an external limiting network such as the circuit shown in figure 8 is recommended. It provides compliance with transients according to IEC/EN 61000-4-5, level 2. The comp- onents are specified in table 5. If 40IMX4 converters should withstand 150 V transients according to 19Pfl1, the same external circuitry with similar components as shown in figure 8 can be used. Fuse and Reverse Polarity Protection The suppressor diode on the input also protects against reverse polarity input voltage. An external fast fuse is required to limit this reverse current; see table below.

BCD20006-G Rev AC, 06-Jul-2012 Page 7 of 12 www.power-one.com Thermal Considerations If a converter, mounted on a PCB, is located in free, quasi- stationary air (convection cooling) at the maximum ambient temperature T A max (see table Temperature specifications) and is operated at nominal input voltage and output power, the case temperature T C 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 depend on input voltage, output current, airflow, temperature of surrounding components and surfaces and the properties of the printed circuit board. T A max is therefore only an indicative value, and under practical operating conditions, the ambient temperature T A may be higher or lower. Caution: The case temperature T C measured at the measuring point of case temperature TC (see Mechanical Data) may under no circumstances exceed the specified maximum. The installer must ensure that under all operating conditions T C remains within the limits stated in the table Temperature Specifications. Short Circuit Behavior The current limitation shuts down the converter, when a short circuit is applied to the output. It acts self-protecting, and automatically recovers after removal of the overload condition.Output Overvoltage Protection The outputs are protected against overvoltages by Zener diodes. In the event of an overvoltage, the converter 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 converters are not designed to withstand external overvoltages applied to the outputs. Connection in Series The outputs of single or dual-output models can be connected in series without any precautions, taking into consideration that the output voltage should remain below 60 V for SELV operation. Fig. 9 Overload switch-off (hiccup mode). 100 Vo [%] t [ms] 05041a 0.3 s overload short circuit condition switch-off Connection in Parallel Several converters with equal output voltage can be connected in parallel and will share their output current quite equally. However, this may cause start-up problems and is only recommended in applications, where one converter is able to deliver the full load current, e.g., in true redundant systems.

BCD20006-G Rev AC, 06-Jul-2012 Page 11 of 12 www.power-one.com Safety and Installation Instructions Installation Instruction Installation of the dc-dc converters must strictly follow the national safety regulations in compliance with the enclosure, mounting, creepage, clearance, casualty, markings and segregation requirements of the end-use application. Connection to the system shall be made via a printed circuit board; see Mechanical Data. The converters should be connected to a secondary circuit. Do not open the converter. Ensure that a converter failure does not result in a hazardous condition. To prevent excessive current flowing through the input lines in case of a short-circuit, an external fuse specified in table 6 should be installed in the non-earthed input supply line.

The converters are approved according to UL/CSA 60950,IEC 60950-1:2001 and IEC/EN 60950-1 2nd Edition. The converters have been evaluated for:  Building-in  Basic insulation input to output, based on their maximum input voltage  Pollution degree 2 environment  Connecting the input to a secondary circuit, which is subject to a maximum transient rating of 1500 V for 20IMX4 and 40IMX4, and 2000 V for 70IMX4 models. The converters are subject to manufacturing surveillance in accordance with the above mentioned standards and with ISO 9001:2000. Railway Applications To comply with railway standards, all components are coated with a protective lacquer (except option Z). Protection Degree The protection degree of the converters is IP 30, except open- frame models (option Z). Cleaning Liquids In order to avoid possible damage, any penetration of cleaning fluids should be prevented, since the power supplies are not hermetical sealed. However, open-frame models (option Z) leave the factory unlacquered; they may be lacquered by the customer, for instance together with the mother board. Cleaning agents are not permitted – except washing at room temperature with isopropyl alcohol. If necessary, the mother board must be cleaned, before fitting the open-frame converter. Note: Cleaning liquids may damage the adhesive joints of the ferrite cores. Isolation The electric strength test is performed in the factory as routine test in accordance with EN 50116 and IEC/EN 60950, and should not be repeated in the field. Power-One will not honor any warranty claims resulting from electric-strength field tests.
