The values suggested are as shown in Table 1. If additional filtering is required, the capacitance may be increased, or expanded to an LC network as shown in Figure 1. - Minimum loading The converter needs a minimum of 10% loading to maintain output regulation. Operation under no-load conditions will not cause immediate damages but may reduce reliability, and cause performance not to meet specifications. - Protection The converter has minimal protection against input over-voltage or output over-load, and may be permanently damaged if exposed to these conditions. An input clamping device can be used for input voltage limiting. An input fuse or an output fuse can also be used to protect against over-loading. Table 1 Input Voltage 5V 12 V 24 V External Input Capacitance 4.7 F 2.2 F 1.0 F - Unregulated input As fixed input converters, this series can accept voltages within a limited range of the nominal input. Otherwise the converter may not function properly or may be damaged. - Output filtering An output capacitor as shown in Table 2 may be used to reduce output ripples and noise. requirements as shown in Table 2. Output capacitance may be increased for additional filtering, but should not exeed 10F. It can also be expanded to an LC network as in Figure 1. +Vin L C -Vin L +Vout DC DC C COM L C -Vout Table 2 Vout 5V 9V 12 V 15 V External Ouput Capacitance 4.7 F 2.2 F 1.0 F 0.47 F V-Infinity, LLC, 20050 SW 112th Ave., Tualatin, OR 97062 www.v-infinity.com 1-866-372-1258 |
