An updated version of the Xantrex XTR Series of programmable DC power systems, which provides up to 850 W from a 1U half-rack package, is now available from TTi (Thurlby Thandar Instruments). 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 for a broad range of requirements.

High-frequency soft-switching technology is used to produce the highest power density available from any manufacturer. With 12 voltage-current variants included in the range, there is a configuration available to meet every application.

The XTR is supplied as standard with USB 2.0, RS-232, RS-485, isolated and non-isolated analogue interfaces to provide a comprehensive set of options to connect to a PC or other network device. This design 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 allows 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, 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 has been designed with reliability in mind, with soft switching technology used to ensure higher mean time between failure (MTBF) by eliminating the potentially damaging high-voltage transients found in conventional hard-switching power supplies.
