Saelig Company has introduced the QPX1200SP - a 1.2kW DC bench-top power supply featuring PowerFlex regulation, designed to meet the need for flexibility in the choice of voltage and current. It offers voltage and current combinations for a very wide range of applications between 60V/20A and 20V/50A. The QPX1200SP includes a linear output stage within its PowerFlex regulator, which gives it a very low output noise of less than 3 mV rms, and a transient recovery time typically ten times better than conventional switch mode units.
The QPX1200SP is fully digitally controlled using instrumentation-quality 16 bit DACs. Front-panel adjustment is by numeric keypad or spin wheel, and remote control interfaces of analog, RS-232, USB and LAN (Ethernet) are included as standard. The LAN interface conforms to the familiar LXI standard (LAN eXtensions for Instrumentation), with a GPIB interface available as an option.
Unlike most higher-power laboratory PSUs, the QPX1200SP is equally suited to bench or rack-mount applications since output and sense terminals are provided on both the front and the rear panels. The case has convenient integral tilt feet for benchtop convenience, but a 3U rack mount is also available. Up to 10 power set-ups can be saved and recalled via the keyboard or remote interfaces. The built-in power limiter features over-voltage, over-current, and temperature trips.
A large dot-matrix backlit LCD provides a 5-digit voltage as well as a 4-digit current display, as well as indicating limit values, memory contents, and a wide range of helpful alpha-numeric messages. Limits settings can be displayed simultaneously with measurements.
The QPX1200SP operates on 110V to 240V AC ±10%, 50/60Hz input and is completely silent due to its convection cooling design. Weighing 20 lbs., its sturdy 3U case is 13.8" x 5.1" x 16.3" (WxHxD).
Made by Aim-TTi, a leading European test equipment manufacturer, the QPX1200SP is available now at $1,700.00 from Saelig Company, Inc. Fairport, NY.
