Flexible Paralleling

Supports multi-unit paralleling for power expansion; no accuracy calibration is required after paralleling.

Short-Circuit Testing with Strong Shock Resistance

The unique DC power supply overcurrent protection technology meets customer requirements for short-circuit testing conditions.

Voltage Slew Rate up to 300V/ms

Meets the load-dump voltage transient test conditions for new energy vehicles.

Electronic Load Function

The electronic load function offers a total of 8 selectable operation modes: Constant Voltage (CV), Constant Current (CC), Constant Power (CP), Constant Resistance (CR), CV+CC composite mode (CV CC), CV+CR composite mode (CV CR), CC+CR composite mode (CR CC), and CV+CC+CP+CR composite mode (Auto).

Battery Simulation Function

The battery simulation function is specifically designed to emulate the characteristics of traction batteries. The battery simulator can accurately and efficiently perform simulation tasks for various battery types, voltage levels, and power ratings. It supports bidirectional simulation, capable of emulating both charging and discharging characteristics.

PV Simulation Function

Supports static PV, dynamic PV, automated testing, and shading tests, etc. The dynamic MPPT test incorporates Sandia & EN50530 dynamic MPPT test items, designed to simulate I-V curve tests under irradiance and temperature variations that mimic real-world weather conditions, thereby evaluating the dynamic MPPT tracking efficiency of photovoltaic inverters. The shading test allows users to design their own PV array, enabling the setting of parameters such as irradiance and temperature for PV modules, as well as the direction and timing of dynamic shading changes. It is used to simulate I-V curves under actual cloud movement or shading by other objects (such as trees or buildings).

Battery Charge/Discharge Test

Integrated Battery Testing: Support comprehensive charging and discharging tests for all battery types. It enables independent static charging or static discharging tests, as well as combined charge-discharge cycles, also known as dynamic tests.

Used for testing products such as photovoltaic inverters, energy storage converters, energy storage DC/DC converters, new energy vehicle electronic control benches, charging piles, and precision air conditioning compressors.
