The CPX series 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 TTi PowerFlex design of the CPX series 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 & current combinations for the CPX400D include 60V/7A, 42V/10A, 28V/15A, and 20V/20A
Building upon success
The CPX400 series, now comprising five models, was developed from the CPX400A – one of the most successful power supplies ever.
Analog controls with digital stability
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 CPX400 series retains the true analog controls of its predecessor.
