High-density 500W programmable power supplies

The Xantrex XPD range of power supplies, now available in the UK from TTi (Thurlby Thandar Instruments), provides 500W of programmable DC power in a quarter-rack chassis.

The Xantrex XPD range of power supplies, now available in the UK from TTi (Thurlby Thandar Instruments), provides 500W of programmable DC power in a quarter-rack chassis.

The small size (109 x 132 x 297mm) and high power density make the new supplies suitable for benchtop and OEM applications where wide adjustment of output voltage or current is required in a compact package of clean power.

The XPD range uses state-of-the-art zero-voltage or soft-switching technology that virtually eliminates switching transients and contributes to the high efficiency, low noise and high reliability.

All models in the range are power-factor corrected for low current draw and reduced generation of input-current harmonics.

Analogue programming is available as standard, and optional 16bit GPIB (IEEE488) and RS232 interfaces are also available.

Remote programming and monitoring accuracy is 1% of full scale for the default range.

Universal mains input (84 to 264V AC, 47 to 63Hz) allows worldwide use without transformer adjustment.

Input current harmonics meet the IEC 1000-3-2 standard.

High-resolution setting of voltage and current limit is achieved using 10-turn front-panel knobs.

Separate large front-panel digital displays give a clear indication of voltage and current settings.

For systems applications, a 19in rack-mount kit is available.

This will accommodate four XPD units or any combination of XPD, HPD or XT units from the Xantrex range.

The XPD range features both front and rear connectors as standard.

Five-way binding posts are fitted to the front panel.

The rear panel has busbars for 7.5 to 33V units and wire clamp connectors for 60 to 120V units.

Five models are available in the XPD range.

These include voltages from 0-7.5 to 0-120V and respective currents from 0-67 to 0-4.5A.

All XPD units cost GBP 1010 (plus VAT).
