Technical FAQs 3

What is a programmable power supply?

Programmable power supplies can be remotely controlled by an input signal, trigger, or PC (by USB, RS-232, or GPIB communications) for automated use. They are often used in manufacturing and laboratory applications because of their flexibility. Some have multiple outputs. Do you need a stepped pattern or PC communications?

What is a linear power supply?

Linear Power Supplies are a simpler design and lower in cost and efficiency. Voltage is stepped down, then rectified and filtered. At higher currents the step down translates to larger footprint and heavier components: transformers, heat sinks and cooling fans.

How many USB ports does a regulated power supply have?

④Two USB Ports: This regulated power supply is equipped with two USB ports. Rear USB interface (upgrade program, upper computer control interface); front 5V 1A USB interface can be used to charge mobile phones.
