Product Description:

The latest ws-6500am / ws-6600am Series modular programmable load launched by wenshun Electric is applicable to the R & D and factory inspection of AC charging pile, DC charging pile, DC power battery pack, DC power supply, battery pack, DC converter and other products. The modular load adopts the imported industrial protective outer box as the main box frame, so that the equipment has good safety protection, insulation performance, shock absorption and seismic effect, meets the use of conventional laboratories and factories, and is suitable for complex working environments, such as vehicle mounted, outdoor applications and other special occasions. The module load supports vertical stacking combined placement, which can greatly save the equipment floor space. The load body also supports the installation of standard 19 inch cabinet, and the product volume is about 1 / 2 of that of similar products.

N load master control: one 10.2-inch industrial touch screen is configured, and the kernel is equipped with the intelligent load control system of wenshun company. Users can realize the intelligent control of load. In addition to the support of the system

In addition to the high and low voltage test mode, it also provides three load working modes of constant power, constant current and constant resistance, which makes the user's test more convenient, and combines the automatic compensation technology to make the equipment more convenient

The accuracy is much higher than that of similar load boxes in the industry. At the same time, a group of extended communication interfaces (Ethernet or RS485) are provided to provide a friendly interface for system integration test and give full play to the greater potential of the equipment.

N load module: the programmable module load is composed of N load module boxes. The load adopts modular design and high power density design, so that the volume of module load is much smaller than that of conventional load equipment,

The control adopts Ethernet or RS485 to connect with the main control box to realize the cascade control of the main control box. The working status of the module load can be obtained through the touch screen interface of the main control box.

Product advantages:

Modular design, easy switching between single machine and parallel machine and flexible use

The load adopts modular design and equipped with wenshun intelligent load control box, which can be used alone or in parallel. Users can flexibly match and select according to the current test power demand

Choose.

Lightweight flexibility and excellent scalability

The high-power density power consumption components independently developed and finalized are adopted to miniaturize the whole equipment. 70% of the whole frame is made of aluminum, which makes it lighter, easier to move, and occupies less space

with

Test in a small space.

The system has flexible scalability to facilitate the increase of station and power in the future and protect the existing investment;

The equipment is suitable for various complex environments. It can be stacked or rack mounted. The installation combination is flexible and convenient.

Safe protection and reliable stability

Imported industrial protection appearance design, good shock absorption and seismic effect, excellent explosion-proof, dust-proof, waterproof and insulation performance.

At the same time, the equipment has multiple intelligent protection functions to monitor the operation status of the equipment in real time.
