Product Feature

Grid Regeneration:

Combines both sourceand load functions. In load mode, energy can be automatically regenerated backto the grid, significantly reducing energy consumption and aligning with greenenvironmental concepts.

Wide Output Range:

The output range isextended to three times that of conventional "matrix" power suppliesof the same power class. Under constant power output mode, it offers moreflexible combinations of voltage and current

High Efficiency Design:

Employs activePower Factor Correction (PFC) technology, achieving a power factor >0.99 atfull load. Coupled with high-frequency LLC multi-resonant inverter technology,the overall efficiency reaches up to 93%.

Multiple Operation Modes:

Supports threebasic operating modes: Constant Voltage (CV), Constant Current (CC), andConstant Power (CP), catering to diverse testing requirements.

Advanced Programmable Functions:

Features 10 non-volatile shortcut groups and 50 sequence tests (each containing20 steps), supporting custom parameter settings and automatic execution.

Comprehensive Simulation Functions:

Includes PV array simulation I-V capability with built-in standard PV testmodes like EN50530 and Sandia. Supports nearly 10 conventional battery curvesimulations and custom battery curve settings, providing complete batterycharge/discharge functions.

High Precision and Stability:

Incorporates precise internal voltage and current measurement modules withexcellent output stability. Voltage setting and measurement accuracy: ≤ 0.05% F.S.; Current setting and measurement accuracy: ≤ 0.10% F.S.

Comprehensive Protection Mechanisms:

Features multiple protections including Over Voltage Protection (OVP), OverCurrent Protection (OCP), Over Temperature Protection (OTP), Vsense reverseconnection protection,and input over/under voltage protection, ensuring thesafety of the equipment and the load.

User-Friendly Operation andDisplay:

Equipped with a 4.3-inch high-brightness color touch LCD display,supporting three control methods: knob, button, and touch, providing anintuitive and easy-to-use interface.

Flexible Scalability:

Supports parallelconnection of up to 10 units of the same model. Some models support seriesconnection to meet higher voltage or current output requirements.

Programming Interfaces:

Standard RS232interface. Optional interfaces include RS485, GPIB, LAN, CAN, USB. Supportsmultiple communication protocols such as ESDR protocol, Modbus (RTU/TCP), andSCPI, facilitating integration into automated test systems.

Optional Analog Interface Control:

Supports remote control via 0-5V/0-10V voltage signals or 4-20mA currentsignals, including start/stop control, voltage/current/power setting, andstatus feedback.

Remote Sense:

Equipped with SENSEterminals to enable output lead voltage drop compensation during high-currentoperation, ensuring voltage measurement accuracy at the load end.
