The BK Precision PVS10005 programmable DC power supply offers clean output power up to 5 kW, excellent regulation, and fast transient response time characteristics in an industry-leading 2U package.

This power supply provides many useful features such as high programming resolution, multiple remote interfaces for test systems, and a built-in SAS (solar array simulator) function to generate PV (photovoltaic) I-V curves. The optional SAS software allows users to consistently reproduce various I-V curves to test a PV inverter’s MPPT efficiency.

For benchtop applications, this series provides an intuitive user interface with full keypad and rotary knob. System integrators benefit from the standard USB (virtual COM), RS232, GPIB, and LAN interfaces supporting SCPI commands. Free application software and a complete set of LabVIEW drivers are available to reduce programming time and increase productivity. The application software allows users to control the power supply, execute test sequences, or log measurements. It also integrates with Data Dashboard for LabVIEW apps, enabling users to remotely monitor select measurement indicators with iOS, Android, or Windows 8 compatible tablets or smart phones.

These power supplies are well suited for both bench use and ATE systems integration, R&D, design verification, production test, and high voltage testing.

Special Applications
In particular, the low-noise characteristic of the PVS Series makes these instruments ideal for motor inverter testing. When operated with the optional SAS software, these power supplies can be used for solar array testing applications.

Intuitive user interface
The numeric keys and rotary knob provide a convenient interface for setting output levels quickly and precisely. Both measured output values and setting values are concurrently displayed on the screen. Additionally, the power supplies provide internal memory for storage of up to 10 different instrument settings that can be set and recalled via both the front panel and remote interfaces.

Remote control and programming

Test system integration
These power supplies offer standard USB, RS-232, GPIB, and LAN interfaces to facilitate test system development and integration. The PVS Series supports SCPI-compliant protocols and come with LabVIEW™ drivers.

Test sequence execution in list mode
The list mode feature allows users to program a list of steps to the power supply’s internal memory and execute them. A total of 100 steps can be allocated to each internal memory location, up to a maximum of 9 locations. The test sequence can be programmed remotely via the USB, RS-232, GPIB, or LAN interfaces using SCPI commands or with the included application software. Test sequences can be configured for single or repeated execution. Each steps’ settings include voltage, current, duration, and output status.

Analog programming and monitoring interface
In addition to front panel and 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 voltage source (0-5 V/0-10 V selectable) or resistance (0-5 k Ω/0-10 k Ω selectable for high voltage models). The analog interface also offers the ability to monitor the output voltage and current, regulation mode (CV or CC), or to indicate the occurrence of a fault condition.

Web server interface
The PVS Series models 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.

Socket and Telnet interface
The power supply can be controlled with SCPI commands using a socket or Telnet connection via the Ethernet interface.

Application software
PC software is provided for front panel emulation, generating and executing test sequences or logging measurement data without the need to write source code.

  • Remote monitoring on iOS, Android, or Windows 8 compatible tablets or smart phones via NI Data Dashboard for LabVIEW apps. Quickly develop a custom dashboard consisting of one (smart phone) or several (tablet) indicators, charts, or gauges to monitor your power supply
  • Log voltage, current, and power values as well as time stamp, CV/CC, and output status
  • Save and load list files to/from the power supply’s internal memory
  • Create an unlimited number of external list files to be executed from PC memory. Save and recall list files to/from the PC

Flexible configuration

Extensive device protection
To protect your DUT, the PVS Series provides several safety features: 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 or high AC input power and turn the output off when this condition occurs.

Convenient front panel guided calibration
Using a 5 ½ digit multimeter, voltage and current parameters can be conveniently calibrated from the front panel via the calibration menu.

Multi-unit control
In multi-unit control mode, up to 30 units can be daisy chained via RS485 and controlled from one master unit through the USB, GPIB, or LAN interface.

Master/Slave operation
Up to four models with the same rating can be connected in parallel and operate in master/slave mode. The RS-485 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.

Solar Array Simulation (SAS) Software Option
Solar inverter designers need to verify their inverter is capable of delivering the maximum power available from solar modules. The I-V curve of solar cells can be influenced by various weather conditions such as a cloudy day. Combined with the SAS application software, PVS users can easily simulate the I-V curve of different arrays under various irradiance conditions while measuring and validating the effectiveness of the inverter’s MPPT algorithm.

SAS Features:

  • Variety of input parameters (Voc/Isc/Vmp/Imp/FF/FFv/FFi)
  • Simulate I-V curve under different weather conditions during a day
  • Monitors and logs real-time voltage, current, power, MPPT efficiency, and average MPPT efficiency
  • User-definable irradiance profile
  • Generate a custom I-V curve with up to 1,024 data points

PV Simulation

  • Solar arrays consist of multiple solar cells characterized by a complex voltage and current profile that is represented in an I-V curve
  • Automatically generate the I-V curve of a solar array in the software by specifying open circuit voltage (Voc), short circuit current (Isc), maximum power voltage (Vmp), and maximum power current (Imp) along with fill factor parameters
  • Use any of the software’s built-in irradiance profiles or generate your own point-by-point irradiance profile
  • Generate an I-V curve manually via a 1,024-point voltage and current table with Notepad or MS Excel and load it in the software
