They are necessary in laboratories, because they are devices or equipment that are capable of converting the alternating current into direct current, being able to regulate it according to the needs of the laboratory area, are used to distribute or power other equipment so that they operate directly from the electrical energy without the need of batteries or batteries.
They typically offer a direct current of 0-30 volts, with variable power between 1 and 5 amps; however, there are different models that can reach 100 volts, 30 amps and more; It will depend on the models and the needs of the laboratory, it consists of a box with several measuring instruments, the voltmeter to read the output voltage in volts, and the ammeter, which gives a more or less faithful indication of the amps circulating between the power supply and the equipment to which it is feeding.
Use of power sources in the laboratory
One of the main uses of power or power sources is to give the necessary electricity to all devices that use electricity, adapting a signal according to the needs of the use to be given, provide a constant flow of electricity, not all sources have the same characteristics, each one is chosen according to the needs of the activity to be performed.
Constantly transmits electrical current, which is necessary to limit current or voltage through the power supply to a specified level, to avoid interruption of the test circuits; in addition, some models of power supplies allow the recovery of current and voltage values frequently used in the laboratory by a simple push of buttons.
How power supplies work in a lab
- With three separate sources, they can be used in series or parallel.
- Standalone mode: Each source acts separately, regulating the voltage and current of each.
- Parallel mode: All three sources have a voltage between 2,7 and 5,5 V and a current between 0 and 7,3 A.
- Serial mode: All three sources the output you get is a voltage between 0 and 69,5 V and a current between 0 and 2 A.
Characteristics of a power source for laboratory use
- Automatic memory function.
- Constant voltage, constant current, constant power, malfunction, intelligent fault warning functions.
- Automatic detection of no load, overload, short circuit, rapid resistance change, ground leak and overheating of the system.
- Molding housing, touch keys, intelligent dual-core microprocessor control.
- With standard timing operation function.
- With standard operation function, sync, V-hr, step by step
