PVS60085

Data Sheet High Power Programmable DC Power Supplies PVS Series The PVS10005, PVS60085, and PVS60085MR programmable DC power supplies offer clean output power up to 5.1 kW, excellent regulation, and fast transient response time characteristics in an industry leading 2U package. These power supplies provide 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 such as validating a solar inverter’s MPPT algorithm and testing to EN50530 and Sandia Labs standards.

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. Rear panel RS-232 interface Output and remote sense terminal 2 USB interface LAN interface RS-485 interface GPIB interface External analog control interface Ground chassis Single-phase AC line input Unlike other 5 kW power supplies that need a 3-phase mains connection, this series only requires a single-phase connection, which is easier to wire and much more commonly available than 3-phase AC outlets. www.bkprecision.com High Power Programmable DC Power Supplies PVS Series Remote control and programming Test system integration Web server interface 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. 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. 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 kΩ/0-10 kΩ 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. 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. 3 • 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. www.bkprecision.com High Power Programmable DC Power Supplies PVS Series Flexible configuration Extensive device protection Multi-unit control 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. In multi-unit control mode, multiple units can be daisy chained via RS485 and controlled from one master unit through the USB, GPIB, or LAN interface. 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. Master/Slave operation 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.

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. Features ■ Variety of input parameters (Voc/Isc/Vmp/Imp/FF/FFv/FFi) ■ Monitors and logs real-time voltage, current, power, MPPT efficiency, and average MPPT efficiency ■ Simulate I-V curve under different weather conditions during a day ■ User-definable irradiance profile ■ Generate a custom I-V curve with up to 1,024 data points ■ Test to EN50530 and Sandia Labs standards 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. PV simulation curve The PVS power supply outputs points on the I-V curve in 1 ms intervals to test the inverter’s MPPT efficiency. 5 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. 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. Use any of the software’s built-in irradiance profiles or generate your own point-by-point irradiance profile. www.bkprecision.com High Power Programmable DC Power Supplies PVS Series Specifications Model PVS60085 PVS60085MR PVS10005 3000 W 0 - 1000 V 0-5A 5000 W Output Rating Output Voltage (1) Output Current (2) Max.
