Description
Configuration: • Input Voltage Option: +26 VDC (+20 VDC to +34 VDC) • Power Input Module Option: Standard • Agency Approval Option: Not Required The GE / Bently Nevada 3300/14 DC Power Supply delivers reliable, regulated power for up to 12 monitors and their associated transducers. A second power supply in the same rack is never required. The Power Supply is installed in the left-most location (position 1) in a 3300 Rack. Primary voltage operation can be ordered for 20 to 34 VDC or 90 to 140 VDC inputs, which are converted for use by the monitors installed in the rack. The 3300 DC Power Supply has over-voltage and under-voltage protection circuitry to shut down the Power Supply should the input supply voltage fall out of the specified range. It will return to normal operation when the input voltage is within the specified range. In addition, the Power Supply is fuse-protected against reverse polarity power hookup and power inputs of greater than 140% of the maximum rated input voltage. Features: • Regulated Power for up to 12 Monitors • Reverse Polarity Power Hookup Fuse Protection • 20 to 34 VDC or 90 to 140 VDC Inputs
1. Functions of the power module The role of the power module is the conversion of voltage, which can convert AC or direct current into the AC or direct current you need. For example, the mains 220V alternating current (AC) is converted into 5V direct current (DC), because the AC 220V electricity is high voltage, and the electronic products are low voltage power supply, which requires a conversion device to convert the AC 220V voltage into low voltage. For example, in the motor vehicle sometimes need to be converted to 220V alternating current to use, then this will become a low voltage to high voltage, because the voltage of the motor vehicle is generally relatively low. In short, it is similar to a mobile phone charger, your mobile phone is out of power, to plug or charge to normal use, but you can not directly connect to 220V use, because the mobile phone will burn, so you need a special conversion device to convert the voltage required by the mobile phone.
Second, how to choose the right power module
1. Circuit design principle and process
The distinction between good and bad circuit principles can usually only be made from a professional perspective. At this stage, the power module can be divided into bare board and potting two kinds, the bare board can be based on intuitive ways, such as the layout of electronic components is reasonable and orderly, generous, orderly, and the solder joint is bright and clean. The potting module can not see the internal situation, but because it is not exposed, it is much better at the level of security and performance indicators. Welding process can include manual welding and wave welding process, mechanized production of wave welding process quality is better than manual welding.
2, chip components
The core of the power supply is IC, it is like the brain of the power supply, the quality of the IC directly affects the parameters of the power supply.
3, transformer components
The transformer determines the power and temperature resistance of the power supply. The transformer is responsible for the completion of AC - DC, energy overload will saturate the machine
4, electrolytic capacitor and ceramic capacitor Electrolytic capacitors, and monolith electrolytic capacitors, which use sulfuric acid as an insulating medium, can make a larger capacity into a smaller volume, and marked with a + symbol on it, and some marked with a - symbol, generally do low-frequency crosslinking and bypass filtering, the disadvantage is that the meson loss is larger, monolith electrolytic capacitors, due to the use of special materials, performance is better than ordinary electrolysis, frequency characteristics are better, However, the capacity can not be too large, and can be used in precise circuits, such as oscillation, or timing circuits. Ceramic capacitors include ceramic dielectric capacity, ceramic capacitor, ceramic tube capacitor and ceramic semi-variable capacitor. It is mainly non-polar, the medium material is better, and the capacity cannot be too large. Suitable for high frequency circuits. 5, batch detection aging and high temperature aging test No matter how well the product material and production process are controlled, it is necessary to detect aging. Because the incoming inspection of electronic components and transformers is difficult to control, only through the aging and high temperature random inspection of the entire batch of power supplies, can we detect the quality stability of this batch of power supplies and whether the materials have safety risks 6. Management means and incoming materials Whether the final management means are strict and the supervision of incoming materials will eventually become the final guarantee of whether the quality of its power supply products can be guaranteed.
