TTi CPX400DP RS232, USB & LXI compliant LANPowerFlex design gives variable voltage and current combinations within a maximum power rangeUp to 60 volts and up to 20 amps180 watts or 420 watts maximum per outputIsolated outputs can be wired in series or parallelConstant voltage or constant current operationSettings Locking (S-Lock) Dual output 840 watt PowerFlex PSU with USB, RS232, LAN The CPX Series of laboratory DC power supplies is one of Aim-TTi's most successful product lines. Tens of thousands of CPX models are in service across the world.PowerFlex regulation allows them to provide higher currents at lower voltages enabling the power to be tailored to suit a wider variety of applications.The range includes single and dual output models with a total power ranging from 360 watts up to 840 watts.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 SuccessThe CPX400 series, now comprising five models, was developed from the CPX400A - one of the most successful power supplies ever.Analog Controls With Digital StabilityAs 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.
