Aim-TTi CPX400D Power Supply Twin 420 'PowerFlex'

The Aim-TTi CPX400D is a different type of laboratory power supply designed to meet the need for flexibility in the choice of voltage and current. A conventional PSU has a fixed current limit giving a power capability that reduces directly with the output voltage. The Aim-TTi CPX400D Power Flex design enables higher currents to be generated at lower voltages within an overall power limit envelope.
Each output can provide considerably higher current than a conventional PSU of the same maximum voltage and power (see power curve). Example voltage and current combinations include 60V/7A, 42V/10A, 28V/15A, and 20V/20A.

As technology has changed, many products have moved from analog controls to digital ones. Although digital controls suit many instruments, they do not necessarily suit a bench power supply. Customer research shows that many users prefer the speed and simplicity of conventional analog controls for setting voltage and current. Digital controls may offer greater precision, but often at the expense of ease-of-use. With this in mind, the CPX400D retains the true analog controls of its predecessor. The main disadvantage of analog controls is stability and security. The settings of analog potentiometers can drift over time. More importantly, the settings can be changed accidentally with potentially serious consequences.

The Aim-TTi CPX400D incorporates S-Lock. One press of the lock button transfers control of voltage and current from the analog controls to internal digital circuitry. This offers not just complete security, but exceptional stability as well with each setting controlled by an instrumentation quality DAC.
