48 Volt Dc 12 Volt Dc Converter Circuit Diagram
How to upload file in html. Jun 17, 2011 - This article demonstrates how to upload multiple files to the server using Silverlight 4.0. Jan 12, 2012 - This article is the continuation of my last article in Silverlight controls series, read last. Let's create a sample page to upload a file to the server. Oct 25, 2009 - Having done some search I've found numerous examples but all of them seemed too complex for the simple task of uploading a file so I. Mar 19, 2009 - In this article, I will discuss how you can create your own File Upload feature in a Silverlight application. Step 1: First, create a Silverlight Web. The Silverlight File Uploader is a Silverlight 2 control (compatible with. All of the other examples that I have found give you a basic example of uploading files.
The IC also contains build in current limiter, built in thermal overload protection and safe area protection. The circuit mentioned here will perform the task of step down fixed voltage DC to DC converter. There are many fixed voltage DC to DC step down converter ICs are available in the market like for DC 5 volt fixed output, is for DC 9 volt fixed output etc. But LM317 is a single IC from which you can get any fix output voltage between 1.2 to 37 volt DC by using suitable values of resistor R1 and R2. The output voltage chart mentioned below will help you in choosing the suitable value of resistor R2 to get the desired output voltage.
You can also use the LM 317 voltage calculator chart mentioned here: In this calculator you can also adjust the value of resistor R1 between 150 to 470 ohms to get the desired output voltage. The input voltage must be 2 to 3 volt greater than the output voltage. Use a suitable heatsink with the IC.
You can also use a variable resistor in the place of R2 if desired more details are here.
Input: 24 or 48 VDC Output: 12, 24, or 48 VDC, 15 – 30 Amps Communication sites require isolated DC Converters to provide excellent voltage regulation, low noise, and high efficiency voltage conversion. Reliability is vital under continuous duty operation and high ambient temperatures. These units accept a wide input range at 24 or 48 VDC nominal, positive or negative ground, and produce pure 12, 24, or 48 volt power.

48 Volt Dc To 12 Volt Dc Converter Circuit Diagram
The solid state circuitry is conservatively designed and semi-conductors are selected and tested to withstand 200% of normal operating power. Input: 24 or 48 VDC Output: 24 or 48 VDC, 1500 – 3000 Watts Convert 48 to 24 or 24 to 48 volts with this compact, high power density (1RU) DC converter system.
12 Volt Dc Power Supply
Wide range input maintains well regulated (isolated) output even when source voltage goes low. Multiple power bays accept 1500 watt converter modules allowing system scalability, load sharing and N+1 redundancy for high reliability. Built-in remote monitoring by Form C alarm contacts alerts operators to major and minor fault conditions. Mobile Mount DC-DC Converters.
Input: 24, 36, 48, 72 or 110 VDC, Positive or Negative Ground Output: 12 or 24 VDC, 6 – 35 Amps Isolated and Spike protected series converters offer the benefits of an isolated converter plus protection against line transients and voltage spikes typically caused by large DC motors and switching transients often encountered on forklifts, locomotives and light rail applications. A transient energy circuit clamps input spikes to a safe level, protecting both the converter and the powered equipment. Rugged case construction and internal components designed for severe vibration applications. Voltage Stabilizers, Mobile Mount.
