Rack-mount power supply delivers 850W
TTi (Thurlby Thandar Instruments) is now offering an updated version of its Xantrex XTR series of programmable dc power systems, which provides up to 850W from a 1U half-rack package.
Designed for test, production, laboratory, OEM and quality-assurance applications, the XTR provides a wealth of features to ensure accuracy and greater efficiency, delivering stable, variable-output voltage and current.
High-frequency soft-switching technology produces what is claimed to be the highest power density available from any manufacturer, and there is a choice of 12 voltage-current variants.
The XTR is supplied as standard with USB 2.0, RS-232, RS-485, isolated and non-isolated analogue interfaces for connecting to a PC or other network device. This provides the convenience of being able to accommodate a wide range of installation configurations. Ethernet and GPIB interfaces are available as options.
XTR power supplies can be connected in parallel or series to produce greater current or voltage outputs, providing a degree of scalability that enables rack-mounted systems to be configured to exactly meet existing requirements while allowing for future expansion.
Up to 30 XTR units can be connected easily via an RS-485 bus to provide a high level of flexibility with remote programming, thereby eliminating the cost and complexity of GPIB cards in each unit. Once connected, multiple power supplies can be controlled via a single LAN, USB 2.0, GPIB, RS-232 or RS-485 interface, providing an efficient option to centrally manage each XTR unit.
To guarantee long-term, trouble-free performance, the XTR features soft switching technology to ensure higher mean time between failures (MTBF) by eliminating the potentially damaging high-voltage transients found in conventional hard-switching power supplies.
