A highly inductive source can affect the stability of the module. An 20 input capacitance must be placed directly adjacent to the input pin of the module, to minimize input ripple voltage and ensure module stability. To minimize input voltage ripple, ceramic capacitors are 10 recommended at the input of the module. Figure 37 shows the input ripple voltage for various output voltages at 3A of load current with 1x22 µF or 2x22 µF ceramic 0 capacitors and an input of 12V. 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 Output Voltage (Volts) 90 1x22uF Figure 38.

Input voltage is 12V. Scope BW requirements of safety extra-low voltage (SELV), the input Limited to 20MHz must meet SELV requirements. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. Output Filtering The input to these units is to be provided with a fast acting These modules are designed for low output ripple voltage fuse (e.g. ABC Bussmann, 250V) with a maximum rating of and will meet the maximum output ripple specification with 20A in the positive input lead. 3x0.047 µF ceramic and 2x47 µF ceramic capacitors at the output of the module. However, additional output filtering may be required by the system designer for a number of reasons. First, there may be a need to further reduce the output ripple and noise of the module. Second, the dynamic response characteristics may need to be customized to a particular load step change. To reduce the output ripple and improve the dynamic response to a step load change, additional capacitance at the output can be used. Low ESR polymer and ceramic capacitors are recommended to improve the dynamic response of the module. Figure 38 provides output ripple information, measured with a scope with its Bandwidth limited to 20MHz for different external capacitance values at various Vo and a full load current of 3A. For stable operation of the module, limit the capacitance to less than the maximum output capacitance as specified in the electrical specification table. Optimal performance of the module can TM be achieved by using the Tunable Loop feature described later in this data sheet. November 4, 2016 ©2016 General Electric Company. All rights reserved.
