Laboratory Power Supplies (UK Only)

LAB / SM Series
  • Extremely compact 100kHz Mos design
  • Power factory correction as standard
  • Analogue and computer interfaces
  • CC/CV modes of operation
  • Current and voltage presets

The LAB/SM series of Laboratory DC Sources provides power outputs of up to 12kW. A wide array of voltage and current ranges are available at each power rating. Constant voltage and constant current operating modes are provided. PFC of 0.98 is standard across the entire range.

Standard features include preset voltage and current outputs, adjustable over voltage protection, remote sense, stand by and thermal overload protection. The combination of automatic ranging with automatic power control often saves the need to acquire a second unit.

The LAB/SM series of power supplies may be remotely controlled using a number of optional analogue and/or computer interfaces. LabVIEW® drivers are also available for GPIB computer control and system integration.

The power supplies are suitable for a wide variety of applications including automotive, general laboratory applications, battery charging and automatic test systems. Exceptional flexibility of design allows virtually any output configuration to be supplied. Please contact our sales office if your requirements are not covered by the standard units.
