Sorensen XG 1700 Watt

1700 Watt, 1U Programmable DC Power Supplies

Product Overview
The XG 1700 is an industry leading programmable DC power supply designed for test, production, laboratory,
OEM and quality assurance applications. The XG 1700 is a 1700 Watt, 1U programmable power supply with
constant voltage and constant current modes, automatic cross-over and numerous features enabling cost effective,
easy integration.

Features And Benefits
Easy Integration
XG 1700 has many control and indication signals such as shutdown, constant voltage (CV) vs. constant current (CC) mode indication, OVP, OCP, OTP, and so on. In addition, the logical-high or -low is free selectable. Thus enabling the XG 1700 to replace existing power supplies with little or no system engineering required.

Free Selectable Analog Control Range
Most DC power supplies provide a 0 to 5 or 0 to 10 V analog control range to control the DC output from zero
to full DC output range. With the XG 1700, the analog control range is free selectable starting at 0V to an upper
range between 2V and 10V. In other words, the analog programming interface range is freely adjustable.

Auxiliary DC Output Channels with Control
In many ATE systems one or more low power, fixed voltage supplies are needed to provide electrical power for any
periphery 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 outputdisconnect or polarity-reversal relays, without needing a
complicated computer controlled relay board.

DC-Waveforms Through Internal Sequencing
To allow for extremely fast programming, sequences can be programmed into and stored in memory using standard
SCPI commands through USB, RS-232/485, LXI or GPIB.

Variable Fan Speed COntrol
The XG 1700’s innovative approach to fan speed is determined by internal heat sink temperature. This allows
the fans to adjust to a constant optimal speed when the output of the supply is being pulsed. This also reduces
noise and increases fan life.

Power Saving Standby Mode
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 minimize lab noise. Since an XG 1700 left in sleep mode is still “on”
the user will have quicker access to an enabled output.

Output Auto Start Mode (Auto Restart)
The Auto Start mode establishes the state of the output of the power supply after recovery from a complete
power cycle (all front panel LEDs are not illuminated), or after recovery from a PC failure or reboot. If Auto Start
mode is set to On, the power supply output will return to its previous value. Also, after the loss of any remote
digital control, the XG unit will remain active in its last programmed setting and will not disrupt any test process.

Auxiliary Auto Start Mode
The Auxiliary Auto Start mode determines the state of the auxiliary output after a complete power cycle (all front
panel LEDS are not illuminated). With Auxiliary Auto Start mode turned to On, the auxiliary output will be activated
after the power supply is powered up again.

Foldback Mode
Foldback mode is used to disable the output when a transition is made between the operating modes. The
power supply will turn off/disable the output and lock in foldback mode after a specified delay if the power supply
transitions into CV mode or into CC 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 CV to CC mode or from CC to CV mode.
