The SP HP Variable DC Power Supply is the ideal product for a wide range of testing, OEM and manufacturing processes applications. It offers 6-18kW in 3U rack and 24-36kW in 6U rack with single or three phase input options. SP HP can operate in constant voltage, constant current and constant power modes and have adjustable voltage/current slew rate. RS485/RS232/USB communication interface (standard), LAN&GPIB communication interface (optional), CAN communication interface (optional). Check out below some of the unique features of the SP HP Variable DC Power Supply and contact our team of engineers if you require further information.
Smart Functions
Graphical User Interface
The large color touch screen provides simple and fast operation for customers, real-time update of display output data and power status. The actual values are properly displayed, so they can be read from a large distance.
Wide Input Voltage Range & High Power Density
3 phase input voltage range from 187-460VAC meets worldwide voltage regulation. 36kW in just 6U. Three phase input applications, no problem at all!!! Check below how to install three 6kW units or three 12kW to obtain a balanced current drawn on the 3-Phase AC mains.
CC & CV Priority
This series power supply provides CC/CV priority function allows the user to select suitable mode correspond to test requirement, let the output be voltage high speed or current no overshoot mode. Below shows an application of CC priority to avoid current overshoot during LED test.
Adjustable Voltage – Current Slew Rate
Providing adjustable rise and fall slew rate setting for voltage and current.
DDS Arbitrary Function Generator
Equipped with a true function generator which can be generate typical functions as displayed below, it is convenient for editing or directly recall. Besides, this arbitrary generator is accessible for the creation and execution of any complex sets of functions, which can be used for testing in development and production.
Built-in Standard Automotive Testing Curves
Built-in German DIN40839 standard voltage curve and the international standard ISO-16750-2 pulse waveform. The fast rise/fall time together with arbitrary function generate ability make it truly simulate the influence on the performance of automotive electronics.
Solar Panel I-V Curve Simulation Function
To simulate the output, I-V characteristics of a solar array includes curve more, use-defined mode and SAS mode. With user-defined mode, user can shape and I-V curve by entering up to 4096 points to simulate dynamic cloud cover effect which is useful for MPPT performance evaluation on PV inverter.
Continuous Source & Sink Function (optional)
Additionally, to the source mode, this Lab Power Supply is equipped with electronic load, also called sink mode, to absorb power. So, the PS work as a two-quadrant power supply. The switching between these two operating modes occurs without interruption and time loss, thus avoiding overshoot of voltage or current.
Use APM DC Electronic Load to Expand Loading Capability
Additionally, to the source mode, this Lab Power Supply is equipped with electronic load, also called sink mode, to absorb power. So, the PS work as a two-quadrant power supply. The switching between these two operating modes occurs without interruption and time loss, thus avoiding overshoot of voltage or current.
Smart 3-Stage Charging Algorithm Simulation
Testing and designers’ engineers can directly recall the default curves or change the switching conditions at different charging stage (bulk, absorption, or float stage). Through optimizing hardware, the current passing from the battery to power supply will be less than 10 mA at any battery voltage when turn off the power supply. It can effectively prevent the power supply from sucking the battery current even without anti-reverse irrigation equipment.
Battery Simulator Function
Built-in typical battery internal resistance curves and discharging curves can easily simulate battery status in real case.
