Ultra-wide range of voltage/current combinations The QPX600DP incorporates full digital remote control using USB, RS-232, LAN Up to 80V and up to 50A within each power envelope and GPIB interfaces. Both models include analog remote control. Isolated tracking of voltage only, or voltage and current PowerFlex+ The QPX600D is a different type of laboratory power supply designed to meet Smart metering and tracking functions facilitate the need for flexibility in the choice of voltage and current. series or parallel wiring for up to 160V or 100A A conventional PSU has a fixed current limit giving a power capability that Low output noise and ripple reduces directly with the output voltage. High setting resolution of 1mV The TTi PowerFlex+ design of the QPX600D enables higher currents to be generated at lower voltages within an overall power limit envelope. Each Variable OVP and OCP trips output can provide more than six times the current of a conventional PSU of Analog control interfaces for voltage and current the same maximum voltage and power (see power curve). GPIB, RS-232, USB and LAN (LXI) interfaces (QPX600DP) PowerFlex+ uses a balanced multi-phase converter system to minimise ripple and improve dynamic performance. Example voltage/current combinations include 80V/7.5A, 60V/10A, 40V/15A, Independent or simultaneous output control 28V/20A, 18V/30A and 10V/50A.

Output and remote sense terminals are mounted on the rear panel along with the analog and logic interface connectors and, on the QPX600DP, the bus interface connectors. The power supply is 3U high and a rack mounting kit (RM310A) is available as an option.
