High-output lab power supply ‘flexes’ between 60 V and 50 A

The new QPX1200 laboratory DC power supply from TTi (Thurlby Thandar Instruments) is a 1.2 kW unit featuring PowerFlex regulation. This enables it to offer voltage and current combinations between 60 V/20 A and 20 V/50 A, making it suitable for a very wide range of applications. The QPX1200 includes a linear output stage within its PowerFlex regulator. This gives it a very low output noise of less than 3 mV RMS, and a transient recovery time typically ten times better than that of conventional switch-mode units.

The unit is fully digitally controlled using instrumentation quality 16-bit digital-analogue convertors. Local setting is by either numeric keypad or spin wheel, and remote-control analogue, RS-232 and USB interfaces are included as standard.

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.

The QPX1200 costs £995 (plus VAT) in the UK.
