The BK Precision XLN3640 is a compact, programmable, single-output DC power supplies, suitable for a wide range of applications. Comparable supplies from other manufacturers primarily address the ATE market, while the BK Precision XLN3640 is designed for both bench top users and system integrators.
For benchtop applications, these power supplies offer built-in voltage and current meters displaying setting and output values concurrently, as well as an intuitive user interface with full keypad and rotary knob.
Standard USB, RS485, and optional GPIB and LAN interfaces combined with fast average command processing times of less than 50 ms make the XLN series ideal for ATE applications. Free application software and a complete set of LabVIEW™ drivers are available to provide remote control capabilities, reduce programming time, and increase productivity.
When greater output power is required, up to four XLN models can be connected in series (high current models only) or parallel and synchronized with the RS485 interface. Alternatively, the RS485 interface can be used to daisy chain up to 31 units and to remotely control them from one master PC via USB, GPIB, or LAN interface.
These power supplies are perfectly suited for ATE systems integration, product design and development, product QC and burn-in testing, and other applications requiring excellent regulation, high power, low noise, and a wide range of voltage and current ratings.
Up to four models with the same rating can be connected in parallel or series (high current models only) and operate in master/slave mode.
The RS485 interface is used for communication between the master and slave(s). Once configured, the master will automatically search for and detect slave units, and display the voltage and current of the complete system.
Fixed 5V/1A output (high current models only)
The high current XLN models offer an additional output with a constant output voltage of 5 V and a maximum output current of 1 A for powering another device.
Extensive device protection
To protect your DUT, the XLN series provides more safety features than any other system power supply in this category: overvoltage (OVP), overcurrent (OCP), overpower (OPP), and overtemperature (OTP) protection. When a fault occurs, the power supply will turn off the output, sound an alarm, and display an error message.
Similarly, with constant voltage-to-constant current (CV-to-CC) or constant current-to-constant voltage (CC-to-CV) foldback protection mode activated, the supply will shut down if load changes force the supply to transition between the two operating modes. The power supply is also able to detect abnormally low AC input power and turn the output off when this condition occurs.
The remote sense feature can compensate for voltage drop in the load wiring
Current flow timer for breaker or fuse testing
The XLN series can be used to accurately measure the time for a fuse or circuit breaker to open. After the voltage and current levels are set, the On/Off button turns on the output and the time when the fuse/breaker opens is measured to the nearest 100 μs. The maximum counting period is one hour.
Convenient front panel guided calibration
Using a 5 ½ digit multimeter and a current shunt, voltage and current parameters can be conveniently calibrated from the front panel via the calibration menu.
Remote access and programming
These power supplies offer standard USB along with optional GPIB and LAN interfaces to facilitate test system development and integration. The XLN series supports SCPI IEEE488.2 and come with LabVIEW™ drivers.
Web server interface
XLN series models with GPIB and LAN interfaces provide a built-in web server that allows users to configure, control, or monitor the basic settings of the power supply from a remote computer using a web browser.
The power supply can be controlled with SCPI commands via a Telnet connection over the Ethernet interface. Any computer with a Telnet client can be used to control the power supply.
In multi-unit control mode, up to 31 units can be daisy chained via RS485 and controlled from one master unit through the USB, GPIB, or LAN interface.
External analog programming interface
In addition to front panel or remote interface control, voltage and current values can also be programmed with an analog control signal. The power supplies can be externally controlled from zero to full scale by either an analog voltage source (0-5 V/0-10 V selectable) or resistance (0-5 kΩ, 0-5 kΩ/0-10 kΩ selectable for high voltage models). High voltage models also provide additional functions to the analog programming interface such as the ability to monitor the output voltage and current, check regulation mode (CC or CV), and indicate whether a fault has occurred.
Test sequence execution in list mode
The list mode feature allows users to download a list of commands to the power supply’s internal memory and execute them. Up to 10 sets of programs can be stored with a total of 150 steps allocated among the memory locations. The test sequence can be programmed remotely via the USB, GPIB, or LAN interfaces using SCPI commands or the included application software. Each step’s voltage, current, and duration parameters can be set, with sequences configured for single or repeated execution.
PC software is provided for creating and executing test sequences in list mode via the USB or GPIB interface. Generate, save, and load program lists. View output characteristic curves and export data to a file. Pass/Fail test monitors maximum and minimum voltage and current values over a specified period of time.
