what should the voltage be on chevy 1500 voltage gauge
General small car 12V (car, SUV, MPV, bread) large car 24V (Steyr, bus). Xenon lamp has good brightness and effect, but if the color temperature is too high > 6000K, the penetration will decrease in rainy and foggy weather. In addition, the normal brightness can be achieved only 1-5 seconds after the xenon lamp is turned on. For 12V vehicle series, the battery voltage should be no-load voltage, which is about 13V. It is normal that the load voltage is not lower than 11V. If it is lower than this voltage, it may be difficult to start. For 24 volt vehicle series, the battery voltage should be no-load voltage of about 26 volts. It is normal that the load voltage is not lower than 22 volts. If it is lower than this voltage, it may be difficult to start. When the battery voltage is converted to low voltage (e.g. 3.3V) and the power reaches 3W, it is necessary to select high-end switching converter, which can provide output power of more than 30W.
This is why automotive power supply manufacturers usually choose switching power supply scheme and reject the traditional architecture based on LDO. For applications with poor air circulation or even no air circulation, if the ambient temperature is high (> 30 ° C) and there is a heat source (> 1W) in the shell, the equipment will heat rapidly (> 85 ° C). For example, most Audio Amplifiers need to install heat sinks and provide good air circulation conditions to consume heat. The current loss of devices that always keep working, such as can transceiver, real-time clock and microcontroller, is the main consideration of ecuiq, and the minimum IQ budget needs to be considered in power supply design. Generally, the no-load voltage of automobile battery is about 13V. If it is lower than 12V, it means that the battery is in an aging state. If the no-load voltage is lower than 11V, it basically means that the battery is about to waste. The normal voltage of non startup is 12.5V, the instantaneous voltage of startup is not less than 10.5V, and the starting generator is not less than 13.5 and not more than 14.8V. The battery voltage should be no-load voltage of about 13V, and the load voltage should not be lower than 11V. If it is lower than this voltage, it may be difficult to start.
