The Intepro PSI 10000 Series is a 30kW Auto-Ranging Programmable DC Power Supply featuring an efficient design coupled with increased performance for applications that demand fast response times, advanced power simulation modes, and precise control. The PSI 10000 Series includes an Integrated Function Generator that allows the creation of arbitrary disturbances for elaborate testing. They also have a galvanically isolated analog interface for voltage, current, power programming, and monitoring. An industry-leading selection of digital remote plug-and-play modules is at your disposal.

Auto-Ranging

Key Features of the PSI 10000 INTELLIGENT PROGRAMMABLE DC SUPPLY products:

  • Auto-Ranging

    Auto-Ranging Output Stage
  • Sequencing

    Integrated Function Generator
  • Simulation

    Photovoltaic Solar Array & Fuel Cell Simulation
  • Emulation

  • Output Power

    From 30kW to >1MW

User and process profiles can be edited, saved, and archived so that the reproducibility of a test or other application is simplified. Also, a single 4U chassis houses up to 30kW of DC power and can be paralleled to over 1MW. Each chassis features a controller that allows the flexibility of operating independently or in parallel for high power applications.

Like our PSI 9000 models, the PSI 10000 features a flexible Auto-Ranging output stage which provides higher output current at reduced voltages, so the source maintains maximum output power across a wide range of voltage operation. Traditional DC sources offer a square operation curve meaning the source keeps the maximum rated current at less than full-scale voltage. A regular 5kW DC source with a voltage range of 500V provides 10A at full scale. At 200V, the source still only offers 10A, so 2kW is delivered to the unit under test.

Auto-Ranging addresses this issue by automatically increasing the output current at reduced voltages. Take the PSI 10500-180, which is 30kW as an example. At 500V, the source offers 60A. At 200V, the source provides 150A, which means the source maintains a 30kW output rating.

Auto-Ranging is especially useful when testing products that require varied input voltages while maintaining regulated output power. This feature often results in a single chassis solution versus buying multiple sources to address low and high voltage / current requirements. It can also help reduce inventory as a single model number can cover many voltages.

The remote sensing function is achieved via dedicated input, which is directly connected to the DUT, to compensate voltage drops along the load cables up to 5% of rated voltage. The power supply detects automatically whether the sensing input is connected and will stabilize the voltage directly at the load.

Integrated Function Generator

The FPGA based control circuit provides additional features such as a function generator using a table-based regulation circuit for simulation of non-linear internal resistances.

Complex Sequence Generator

By linking together several differently configured sequences, complex progression creations will happen. Smart configuration of the arbitrary generator can be used to match triangular, sine, rectangular or trapezoidal wave functions and thus, e.g., a sequence of rectangular waves with differing amplitudes or duty cycles can be produced.

For the implementation of the LabView IDE, Intepro offers ready-to-use components (VIs) to be used with the Ethernet interface. Other IDEs and interfaces may be supported upon request.

Solar Array Simulation

The PSI is an ideal solution for simulating static or dynamic irradiance levels of a solar array. The high accuracy irradiance curve is based on 16,400 data points and adjustable in 1% increments. Isc, Uoc, MPP, and Impp are user-programmable.

Fuel Cell Simulation

An embedded Fuel Cell table function simulates the characteristics of voltage and current of a fuel cell. Define slope points, and the data automatically calculates then transfers to the function generator and output through the DC source.

User Control

The large LCD touch panel offers a modern and intuitive user interface for controlling the four operating modes: Constant Voltage (CV), Constant Current (CC), Constant Power (CP), and Constant Resistance (CR). Response times for the control via analog or digital interfaces by the DSP controlled hardware is among the fastest in the industry. In parallel operation of multiple devices, a master-slave bus is used to connect the chassis to create a high-power system where the actual values are totaled, and the set values distributed.

An Internal resistance control provides a means to virtually simulate an internal resistance (Programmable Impedance), which is in series to the voltage source and thus also in series to the load. According to Ohm’s Law, this causes a voltage drop, which will result in a difference between the adjusted output voltage and the actual output voltage. This is beneficial for the simulation of various lengths of different types of cables to emulate loading effects.
