— Programming Guide & Drivers —
A single 1U chassis houses up to 3kW of DC power. The clearly arranged control panel features two rotary knobs, six pushbuttons and two LEDs. Together with an illuminated blue display for all values and status, simplifying use of the device.
The PS 9000 3U model allows the user to achieve even higher output power, up to 15kW. Cabinets with up to 150 kW and up to 42U size can be configured to suit various requirements.
All PS 9000 models feature 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 maintains maximum rated current at less than full scale voltage. A traditional 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 actually delivered to the unit under test.
Auto-Ranging addresses this issue by automatically increasing the output current at reduced voltages. Take the PSI 9500-30 which is 5kW as an example. At 500V the source offers 10A. At 200V the source provides 25A which means the source maintains a 5kW 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 many voltages can be covered by a single model number.
The remote sensing function is achieved via dedicated input which is directly connected to the load equipment, in order to compensate voltage drops along the load cables up to a certain degree. The power supply detects automatically whether the sensing input is connected and will stabilize the voltage directly at the load.
The large LCD panel offers a modern and intuitive user interface for controlling the four operating modes: Constant Voltage (CV), Constant Current (CC) and Constant Power (CP). Response times for the control via analog or digital interfaces by the FPGA controlled hardware are among the fastest in the industry. In parallel operation of multiple devices, a master-slave bus is used to connect the chassis to a create high power system.
