The XG 1500 is an industry-leading programmable DC power supply designed for testing, production, laboratory, OEM, and quality assurance applications. 

The XG 1500 is a 1500 Watt, 1U programmable DC 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 1500 DC power supply 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 1500 to replace existing DC 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 1500 variable DC power supply, 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 1500 DC output power supply 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.

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 1500’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 1500 DC power supply 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 1500 left in sleep mode is still “on” the user will have quicker access to an enabled output.

Key Modes 

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 the Auxiliary Auto Start mode turned 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.
