What is Astron RS 20A used for?

What is Astron RS 20A used for?

The Astron RS series are continuous duty power supplies designed to withstand the rigors of heavy-duty or industrial use. RS-20A has a continous 16 amp rating with a 20 amp intermittent duty rating @ 13.8VDC. (50% duty cycle: 5 min on / 5 min.

Where are Astron power supplies made?

Made in the USA
Since 1976, Astron Corporation has been a premier manufacturer of Linear Power Supplies. Made in the USA, our Linear Power Supplies have reliably served Commercial and Ham operators alike for over forty years.

What is Astron RS 12A used for?

The RS-12A is a 300 Watt DC Power Supply from Astron. Supplies DC Voltage and Current to test, design, and troubleshoot electric and electronic circuits. Applications include Burn In, QA, ATE, Research, Design, and Education to name a few.

What is linear power supply?

What is a Linear Power Supply? Linear power supplies are designed for low noise and are often considered quiet since there is no high-frequency switching. They are used anywhere that excellent regulation and/or low ripple is required as well as needing low electromagnetic emissions and excellent transient response.

What is the difference between a switching and linear power supply?

In a linear power supply, the frequency input from an outlet or other source is input directly to the transformer, whereas in a switching power supply, the current after rectification is sent to the transformer as a high-frequency pulse.

Is a linear power supply better?

Linear regulated is ideal for applications that require low noise, whereas switching power supplies are better suited for handheld devices where battery life and efficiency is important.

How do I adjust the voltage on my power supply?

Although there are +/- output models that cannot be adjusted, the output from most Power Supplies can be adjusted by turning the voltage output adjuster (V. ADJ). The voltage will increase when the adjuster is turned clockwise. The voltage will decrease when the adjuster is turned counterclockwise.

What are the drawback of linear regulator?

Linear regulators are ideal for many low-power applications so when a higher power is needed, the disadvantages become more apparent. These disadvantages to linear power supplies include size, high heat loss, and lower efficiency levels when compared to a switch-mode power supply.

When would you use a linear power supply?

Linear power supplies are designed for low noise and are often considered quiet since there is no high-frequency switching. They are used anywhere that excellent regulation and/or low ripple is required as well as needing low electromagnetic emissions and excellent transient response.

How do I change the current on my power supply?

You simply turn on the power supply without load, turn the current knob counterclockwise until it stops. Short the output terminals (between + and – terminals) with appropriate sized wire, and adjust the current knob to the level you want (you may need to raise the voltage limit if you ran into CV mode).

Can linear regulator increase voltage?

Moreover, the inability of a linear regulator to boost a voltage is a problem when one component in a product demands a higher voltage than all the others. Similarly, when some analog circuitry requires a negative voltage, the linear regulator can’t be used because of its inability to invert the positive supply.
