4. REGULATED DC POWER SUPPLY(MODEL LQ6324)  ( 10 Nos.)

 A regulated power supply is an embedded circuit; it converts unregulated AC into a constant DC. With the help of a rectifier it converts AC supply into DC. Its function is to supply a stable voltage (or less often current), to a circuit or device that must be operated within certain power supply limits. The output from the regulated power supply may be alternating or unidirectional, but is nearly always DC.

Overview And Features:

• Laboratory bench unit.
• Fully protected against overload and short circuit.
• Three independent outputs electrically isolated from each other.
• 5V/5A with over voltage crowbar protection for digital ICs.
• Electrically floating outputs.

• Optional features with extra cost.

5. 3MHZ FUNCTION GENERATOR ( 10 Nos. )

6. LAN-T  TRAINER  ( 1 Nos.)

 The LAN-T Benchmark trainer is useful for study and development of reliable data transfer protocols, networking layers and applications. The Trainer exposes users to networking concepts at the physical, MAC network and transport layers, through a series of designed experiments. The experiments reinforce the theory covered in lectures, while the ‘hands-on’ programming exercises train students to industry level. The trainer can also be used for project work involving many layers of the network hierarchy.

7. LASER PRINTER ( 1 No.)

 A laser printer is a popular type of personal computer printer that uses a non-impact (keys don't strike the paper), photocopier technology. When a document is sent to the printer, a laser beam "draws" the document on a selenium-coated drum using electrical charges. After the drum is charged, it is rolled in toner, a dry powder type of ink. The toner adheres to the charged image on the drum. The toner is transferred onto a piece of paper and fused to the paper with heat and pressure. After the document is printed, the electrical charge is removed from the drum and the excess toner is collected. Most laser printers print only in monochrome. A color laser printer is up to 10 times more expensive than a monochrome laser printer.

8. OSCILLOSCOPE ( 10 Nos.)

 An oscilloscope is a laboratory instrument commonly used to display and analyze the waveform of electronic signals. In effect, the device draws a graph of the instantaneous signal voltage as a function of time.

A typical oscilloscope can display alternating current (AC) or pulsating direct current (DC) waveforms having a frequency as low as approximately 1 hertz (HZ) or as high as several megahertz (MHZ). High-end oscilloscopes can display signals having frequencies up to several hundred gigahertz (GHZ). The display is broken up into so-called horizontal divisions (hor div) and vertical divisions (vert div). Time is displayed from left to right on the horizontal scale. Instantaneous voltage appears on the vertical scale, with positive values going upward and negative values going downward.
