QPX Series Features:

• PowerFlex design with 1200 watts maximum power
• Wide range of voltage/current combinations
• Up to 60V and up to 50A within a 1200W power envelope (NOTE: Volts x Amps cannot exceed 1200 Watts)
• Linear final regulation provides very low output noise and fast transient response
• Setting by direct numeric entry or by spin wheel
• High setting resolution of 1mV in up to 60 volts
• Multiple non-volatile setting memories
• Variable OVP and OCP trips
• Low resistance and power calculation
• Analog control interfaces for voltage and current
• Bench or rack mounting with front and rear terminals
• RS-232, USB & LAN (LXI) interfaces (QPX1200SP)

The QPX1200S is a laboratory dc power supply with a maximum total output power of 1200 watts and is suited to both bench-top and system applications. The QPX1200SP adds full digital remote control using USB, RS-232, LAN (LXI-C) interfaces. Both models include analog remote control.

PowerFlex

PowerFlex CurvePowerFlex
The QPX1200S 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 PowerFlex design of the QPX1200S enables higher currents to be generated at lower voltages within an overall power limit envelope. Each output can provide three times the current of a conventional PSU of the same maximum voltage and power (see power curve).

Example voltage/current combinations include 60V/20A, 48V/25A, 37.5V/30A, 26V/40A, and 20V/50A.

The PowerFlex regulator includes a linear output stage giving the QPX1200S exceptionally low output noise for a unit of this power, and ensuring good transient response

Bench or Rack Mounting
The QPX1200S is housed in a 350mm (13.75") wide case suitable for use on the bench-top. Output and remote sense terminals are mounted both on the front and on the rear panel along with the analog and logic interface connectors and, on the QPX1200SP, the bus interface connectors. A rack mounting kit is available as an option (requires 4U of rack space).
