Technical FAQs 4

What is a variable power supply?

View & Download the Guide A variable power supply provides precise, adjustable voltage and current for circuit testing, device validation, and troubleshooting. With clean, stable output and real-time control, it ensures accurate, repeatable measurements in R&D, production, and educational labs.

Can variable frequency drive be used for power supply?

In principle, it can not be used for power supply, and variable frequency drive is generally used for speed regulation of three phase asynchronous motor. The whole circuit of frequency converter consists of AC-DC-AC-Filter Circuit, so the output voltage and current waveform are pure sinusoidal, which is very close to the ideal AC power supply.

What is a programmable power supply?

Programmable power supplies (CVCC variable DC power supplies, DC power supplies) are power supplies that can be operated in constant voltage (CV) mode or in constant current (CC) mode automatically depending on load conditions within the range of voltage values and current values that have been set ahead of time.

Is TDK-Lambda a programmable power supply?

The standard Z+ series now also includes USB and optional LAN. TDK-Lambda's lineup of programmable power supplies consists of the Genesys series suitable for 19 inch racks mounted and the portable benchtop-type Z+/ZUP series for applications such as researching, and all are UL-listed products with RS232C/RS485 in their standard form.
