The QPX1200SP adds full digital remote control using USB, RS-232, LAN and Power calculation GPIB interfaces. Both models include analog remote control. The meter for each output can be set to show the total power currently being PowerFlex provided to the load (V x A) to a resolution of 0.1 watts. The QPX1200S is a different type of laboratory power supply designed to meet The power is shown in addition to the voltage and current values. the need for flexibility in the choice of voltage and current. Low resistance calculation A conventional PSU has a fixed current limit giving a power capability that The meter for each output can reduces directly with the output voltage. be set to show the equivalent The TTi PowerFlex design of the QPX1200S enables higher currents to be resistance of the load by generated at lower voltages within an overall power limit envelope. Each displaying voltage divided by output can provide three times the current of a conventional PSU of the same current. maximum voltage and power (see power curve). Low resistance measurements Example voltage/current combinations include 60V/20A, 48V/25A, 37.5V/30A, using a DMM utilise a low excitation current and suffer from thermal emf 26V/40A, and 20V/50A. errors and other low voltage effects. The PowerFlex regulator includes a linear output stage giving the QPX1200S This function enables low resistance measurements to be made at high exceptionally low output noise for a unit of this power, and ensuring good currents by using the remote sense terminals to create a four terminal transient response connection. This can give much more reliable results for certain component Bench or rack mounting types, such as magnetics, which operate at ampere levels. The QPX1200S is housed in a 350mm (13) 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. The power supply is 3U high and a rack mounting kit (RM310 or RM310A) is available as an option.
