QPX1200S直流电源,英国tti QPX1200S的产品描述：
Unrivalled Flexibility
The QPX1200 offers users a level of flexibility that can not be achieved with conventional laboratory power supplies.
With a current capability of 20 amps at the maximum output of 60 volts, its PowerFlex design offers increasing output current with reducing output voltage. The QPX1200 can therefore perform the task of many different power supplies.
Example voltage/current combinations include 60V/20A, 48V/2, 37.5V/30A, 26V/40A, and 20V/50A.
High precision
With setting controlled by an instrumentation quality 16 bit DAC, the QPX1200 offers high accuracy and stability.
Local setting can be done using either the numeric keypad or the spin-wheel, and setting resolution is 1mV in up to 60 volts.
Linear output stage for low noise
Mixed mode regulation with a linear output stage gives the QPX1200 exceptionally low output noise for a unit of this power, and ensures fast transient response.
Bench or rack mounting
Unlike most higher power laboratory PSUs, the QPX1200 is equally suited to bench or rack-mount applications.
Output and sense terminals are provided on both the front and rear panels. The case has integral tilt feet, and a 3U rack mount is available as an option.
A wide range of interfaces
The QPX1200S has an analog remote control interface only.
The QPX1200SP has analog, RS-232, USB and LAN (Ethernet) and GPIB interfaces. The LAN interface is fully LXI compliant.QPX1200S直流电源,英国tti QPX1200S的技术参数：
