Compact bench power supply provides 175W
The EX355, new from TTi (Thurlby Thandar Instruments), is a single-output laboratory DC power supply providing an output from 0 to 35V at 0 to 5A.
Programmable power-supplies offer outputs to 1kW
The XHR range of programmable power supplies, offering output ratings up to 1 kW is power-factor corrected for low current draw and reduced generation of input current harmonics.
The interface features an auto-sensing 10/100Base-T network interface that provides fast programming and readback using an extensive command set.
The user can select between the factory default Ethernet or RS232 control by adjusting internal jumpers on the installed interface card.
The Xantrex XFR series can also be programmed via the standard remote analogue programming or using the traditional 16bit GPIB or RS232 interface options.
All Xantrex XFR models use "soft switching" or zero-voltage technology.
This virtually eliminates switching transients, and noise performance is closer to that of linear units.
In addition, efficiency is increased, heat generation is decreased, and stress on the switching transistors is greatly reduced, improving reliability.
XFR models are available in 18 standard models from 7.5 to 600V DC output, all generating full power over the total operating range of 0-50C without derating.
Owing to their excellent thermal management, Xantrex units can be stacked in power racks without the need to leave ventilation gaps between units.
Power density is also very high with the 1.2kW models housed in a 1U rack case and the 2.8kW in 2U size.
