High-performance 1700 W DC power supply

A new higher-power range of the Sorensen XG Series of high-performance DC power supplies has been released by TTi distribution, the exclusive partner for Ametek Programmable Power in the UK.

High-performance 1700 W DC power supply

The new XG 1700 series uses high-frequency soft-switching technology to provide up to 1700 W in 12 models with outputs ranging from 0-6 V up to 0-600 V. The units are housed in compact 1U-size cases, and include standard USB, RS232/485 and analogue control interfaces. The analogue control range is freely selectable from zero voltage to an upper range between 2 and 10 V. LAN and GPIB interfaces are available as options.

To allow for extremely fast programming, sequences can be programmed and stored in memory using standard SCPI commands.

In many ATE systems, one or more low-power fixed-voltage supplies are needed to provide electrical power for peripheral units within the ATE cabinet. For this purpose, the XG 1700 provides two standard auxiliary DC output channels. Both auxiliary power channels are controllable directly from the front panel or through SCPI commands. With these channels, it is possible to drive output-disconnect or polarity-reversal relays without needing a complicated computer-controlled relay board.

Foldback mode is used to disable the output when a transition is made between the operating modes. The power supply will turn off or disable the output and lock in the foldback mode after a specified delay if the power supply switches to constant-voltage or constant-current mode, depending on the foldback mode settings. This feature is particularly useful for protecting current or voltage sensitive loads. Foldback can be set to trigger a switch when transitioning from constant-voltage to constant-current mode or vice versa.

When the XG 1700 has been in an idle state, the supply can go into 'sleep mode', much like a computer monitor. This will allow the user to save energy and minimise noise in the working environment. Since an XG 1700 left in sleep mode is still 'on', the user will have quicker access to an enabled output.
