A highly efficient input filter and an active inrush current limiter ensure a very low inrush current of short duration. This prevents circuit breakers and fuses from tripping at switch-on. All CPA models have an additional bridge rectifier and a boost converter to provide active power factor correction (PFC) according to EN 61000-3-2. The CPx200/250 models (see fig.1a) are equipped with two independent high efficient 2-switch forward converters, switching 180 out of phase to minimize the ripple current at the input. On the secondary side, two high-current synchronous rectifiers supply Vo1 (5 V) and Vo2 (3.3 V) with up to 40 A. The secondary-controlled Vo3 (+12 V) post regulator is supplied by an additional winding of the 3.3 V main transformer. The linear regulator for Vo4 (-12 V) is supplied from the output choke of the Vo3 output. The output filters reduce ripple and noise to a minimum without compromising the dynamic response. The models CPD500 (fig. 1b) and CPA500/550 (fig. 1c) exhibit nominal output voltages and output currents, degree of protection, batch no., serial no., and data code including production site, modification status, and date of production. Identification of LEDs on the front panel. a third forward converter for both outputs Vo3 and Vo4. The outputs Vo1 an Vo2 provide up to 50 and 60 A. All outputs are fully regulated and protected from the bus by decoupling FETs or diodes. A current monitor calculates the output power. As soon as the output power exceeds the maximum threshold level, the converter starts to reduce the output power by decreasing the output voltages. In contrast to the outputs Vo1 (5 V), Vo2 (3.3 V), and Vo3 (+12 V) with active current sharing, output Vo4 (-12 V) has a droop characteristic for passive current sharing. If for some reason the voltage of any output exceeds the nominal value significantly, the converter is permanently shut down. If option L is fitted, this occurs as well, if the max. output current is exceeded for a predefined time. To reset, the input voltage must be removed for a short time. Power-One's Efficient Dual Geometric Edge Technology (EDGE TM ) facilitates high current density, increases reliability by reducing component stresses, and decreases the amount of heat dissipated.

The efficiency is specified in table 1. Its dependence upon the input voltage Vi is shown in fig. 2a (CPA models) and fig. 2b (CPD500 models). The efficiency of CPD200/250 models depends only marginally upon Vi. An incorporated fuse protects the converter against further damage in the case of a failure.

In the case of reversed input voltage, the input fuse will blow; however no further damage will occur. The CPA Series converters are designed for AC input and have a rectifier bridge on the input. 50 100 150 200 Note: The inrush current limitation is achieved using electronic circuitry.

Vi = 22 V, when the input voltage is applied; at decreasing Vi, they switch off at approx. 21 V. Note: The input current I i may exceed I i max, if Vi Vi min. CPD500 models start at Vi = 35 V and switch off at Vi = 33 V. CPA models exhibit an undervoltage trigger controlling startup and shutdown. The threshold is between 80 and 90 VAC. See also Power Fail Signal. Note: CPA200/250 with version V116 should not be operated at Vi Vi min, as these models have no undervoltage shutdown and will therefore operate with a high input current at full load.

Page 8 of 19 CompactPCI (R) CPA, CPD Series Data Sheet 200 - 550 Watt AC-DC and DC-DC Converters Hold-up Time of CPD Models For extended hold-up time of CPD models, use external output capacitors or decoupling diodes and input capacitors of adequate size.

If an overvoltage of 120 - 130% is detected, the converter is permanently disabled. To reset, the input voltage must be removed for 10 - 20 seconds. Note: The models CPA500/550 with version number before V110 need approx. 60 s to recover. Thermal Considerations and Protection external input capacitance [mF] output power [W] efficiency [%] total hold-up time [ms] hold-up time [ms] minimum input voltage [V] threshold level [V] Note: After Vi was removed, the outputs maintain their voltage for the time t h. Even if Vi comes back during t h, but after t h, the output voltage might be affected. Redundant Operation and Hot Swap Due to the integrated ORing FETs/diodes, the converters are designed to be operated in redundant systems. Hot swap is also possible, but the output voltages of each bus may deviate dynamically by 5% during the plug-in / plugout operation. Note: We recommend connecting some capacitors parallel to the bus to limit voltage deviations during hot swapping and during switch-on / switch-off of the input voltage of one of the parallel-connected converters. Output Characteristic and Protection All outputs are fully protected against continuous open-circuit (no load) and continuous short-circuit conditions. All outputs of CPx200/250 models have a constant current limitation with a rectangular characteristic; see figure 3. In addition, the total power from outputs Vo1, Vo2, and Vo3 is limited to Po max, resulting in a free choice of load distribution between these outputs. Output Vo4 is disabled in the case of overtemperature generated by overcurrent. In CPA500/550 and CPD500 models, the total power of all four outputs is limited to Po max. If a converter is mounted in the upright position with airflow as specified in the general conditions of the tables 4 and 5, allowing unrestricted forced-air cooling, and is operated at its nominal input voltage and power at maximum ambient temperature TA max (see Temperatures), the temperature at the measurement point of the case temperature TC (see Mechanical Data) will approach after an initial warm-up phase the indicated maximum value of TC max (105 C). However, the relationship between TA and TC depends heavily on the operating conditions and the system integration. The thermal conditions are significantly influenced by the input voltage, the output current, the airflow, and the temperature of the adjacent elements and surfaces. TA max is therefore, contrary to TC max , an indicative value only. Caution: The installer must ensure that under all operating conditions TC remains within the limits shown in the diagrams fig. 4.

If pin 39 is connected to a return pin (e.g. pin 22), the internal logic will disable all outputs. The inhibit input is protected by a decoupling diode. EN# (pin 27) is CMOS-compatible. However, we recommend to connect it directly with a return pin (e.g. pin 22) to enable the converter. Pin 27 is shorter than the others, ensuring start-up only, after all other pins were connected to the system. This provides true hot-swap capability. 0.1 0 Table 6: Inhibit data Inhibit voltage Vo2SENSE Vo /Vo nom 1 (22) Fig. 6 Inhibit and enable inputs Vinh 5V Note: When a CPA or CPD500 converter is disabled by INH# and/ or EN #, the PFC booster remains active, keeping the boost capacitor Cb (fig. 1) charged. As a result, there is no inrush current at restart. Note: When a CPD 500/550 converter is disabled, on outputs 3 and 4 may appear a little voltage under no-load condition.

Page 10 of 19 CompactPCI (R) CPA, CPD Series Data Sheet 200 - 550 Watt AC-DC and DC-DC Converters Temperature Warning and Shutdown A temperature warning circuitry monitors the case temperature TC. Its output signal V DEG# changes from high to low impedance, when the TC exceeds the upper threshold level, and changes back to high impedance, when TC falls below the lower threshold level, which is 85 C 5 C. Pin 38 (degrade signal DEG#) is internally connected via the collector-emitter path of an NPN transistor to the signal return pin 22. The current I DEG# through pin 38 should not exceed 40 mA, and VDEG# should not exceed 40 V. If TC exceeds 105 C, the converter will be disabled. It resumes operation automatically, once TC falls below 105 C. The threshold levels for Vi correspond to approx. 34 V for CPD models and 80 - 90 VAC for CPA models. Note: CPD200/250 (and CPA200/250 up to version V116) provide only the signal FAL#, but the converter is not inhibited. Note: Vi min of CPA models is considered as insufficient, when - Vi remains for typ. 30 ms below 2 * Vi min. Connector pin 42 (signal VFAL#) is internally connected via the drain-source path of a JFET (self-conducting type) to the signal return pin 22. The current I FAL# should not exceed 10 mA. VFAL# should not exceed 40 V, as the JFET is not protected against overvoltage.

Installation Instructions These converters are components, intended exclusively for installation within other equipment by an industrial assembly process or by a professionally, competent person. Installation must strictly follow the national safety regulations in respect of the enclosure, mounting, creepage distances, clearance, casualty markings, and segregation requirements of the enduse application. Connection to the system shall be made via the mating female connector (see fig. 16). Other installation methods may not meet the safety requirements.

This fuse is designed to break an overcurrent in case of a malfunction of the converter and is not customer-accessible. External fuses in the wiring to one or both input lines (pin 47 and/or pin 46) may be necessary to ensure compliance with local requirements. A built-in second fuse in the neutral line (pin 47) is available as option F for CPA500 models. A second fuse in the wiring to the neutral line or option F may be needed if: * Local requirements demand an individual fuse in each source line * Neutral and earth impedance is high or undefined * Phase and neutral of the mains are not defined or cannot be assigned to the corresponding terminals. Caution: Installation must strictly follow the national safety regulations. Models with option F: Caution! Double-pole/neutral fusing. Do not open the converters, or the warranty will be invalidated! Important: If the inhibit function is not used, pin 39 (i) should be left open-circuit to enable the outputs.

According to IEC/EN 60950, subassemblies connecting input to output are pre-tested with 4.3 kVDC or 3 kVAC. Make sure that a converter failure (e.g. by an internal shortcircuit) does not result in a hazardous condition. Standards and Approvals All converters are safety-approved to EN 60950-1/A12:2011 and UL/CSA 60950-1 2nd Ed +A1. The converters correspond to Class I equipment. The following considerations have been made during design concerning safety: * * * * Build-in component Functional insulation between output(s) and case Use in a pollution degree 2 environment. CPD-models: Basic insulation between input and case/ output, based upon 75 VDC. The input is identified as TNV-2. * CPA-models: Basic insulation between input and case, and double or reinforced insulation between input and output, based upon 250 VAC. * CPA-models up to 60 Hz. Protection Degree The converters correspond to protection degree IP 20, provided that the female connector is fitted. Cleaning Liquids The power supplies are not hermetically sealed. In order to avoid possible damage, any penetration of cleaning and other fluids shall be avoided. Safety of Operator-Accessible Output Circuits If the output circuit of a converter is operator- accessible, it shall be an SELV circuit according to the IEC/EN 60950 related safety standards. However, it is the sole responsibility of the installer to ensure the compliance with the relevant and applicable local safety regulations The converters are subject to manufacturing surveillance in accordance with the above mentioned standards. Isolation The electric strength test is performed as factory test in accordance with EN 50116 and EN/IEC 60950; see table 13. Only the test between input and [case+outputs], marked with footnotes 1 and 2, may be repeated by the customer. Note: The DC test voltage shall be slowly increased (within several seconds) and maintained for max. 2 seconds. Trigger level 25 A. Power-One is executing these factory tests with a reasonable margin, to guarantee its repetition. Test with AC is not possible due to the incorporated Y caps. However, the standards allow testing with a corresponding DC voltage. Power-One will not honor any warranty claims, if the customer provides other or incorrect electric strength tests. Operation at >60 Hz and Leakage Currents Operation up to 440 Hz is possible, but the X and Y caps are not safety-approved to this frequency. The efficiency decreases by approx. 2%, and the leakage currents are proportional higher. BCD20005-G Rev AH, 10-Nov-2014 MELCHER The Power Partners.
