Chen Tech Enters Digital Multimeter Market, Unveils HCM-1000 High-Precision High-Current Meter

Solving Energy Storage and EV Measurement Pain Points: Automatic Range-Switching Technology Sets New Industry Standard

With the booming development of the renewable energy, electric vehicle (EV), and battery energy storage system (BESS) markets, the industry’s demand for “high-precision” and “high-current” DC measurement is experiencing explosive growth. Chen Tech, a leading global provider of power electronics testing solutions, today officially announced the launch of its brand-new “HCM-1000 High-Precision High-Current Meter”. This is not only a major technological breakthrough for Chen Tech, but it also marks the debut of its product line crossing into the digital meter field, providing the industry with more precise and secure power monitoring solutions.

Breaking Through Traditional Limitations to Directly Address Three Major High-Current Measurement Pain Points

In the past, high-current measurement environments frequently faced technological bottlenecks. Traditional shunt resistors (Shunt) or single-sensor methods often generate severe heat and power loss when handling high currents. This not only directly impacts measurement accuracy but also harbors potential safety risks. Furthermore, traditional instruments struggle to balance a “wide range” with “high precision” and lack intuitive user interfaces, resulting in low efficiency for data acquisition and equipment management.

HCM-1000 Series: Smart Switching Technology Defining a New Height in Measurement

Developed by Chen Tech to address the aforementioned pain points, the HCM-1000 Series features the following key innovative highlights, completely revolutionizing existing measurement paradigms:

  • Exceptional Measurement Accuracy and Thermal Stability: The HCM-1000 delivers industry-leading, high-precision, high-current DC measurement capabilities. It effectively overcomes errors caused by thermal loss in traditional methods, ensuring authentic and reliable data.

  • Exclusive Multi-Stage Automatic Range Switching: Equipped with advanced automatic range-switching technology, the instrument automatically shifts to the optimal measurement segment based on the current level. This perfectly solves the long-standing industry challenge of being unable to maintain low-current precision under high-current conditions.

  • Embedded Smart Touch Interface: Featuring an embedded system and an intuitive touch panel, it achieves real-time display and dynamic control. This significantly enhances operational convenience and optimizes data management efficiency, aligning with digital transformation needs.

  • Broad Industry Application: This series is specifically engineered for renewable energy grids, energy storage systems, and EV charging/discharging test environments, offering a highly practical and durable testing platform.

  • Wide Scope of Applications: It delivers superior convenience and accuracy for high-current measurement, current calibration of charging/discharging equipment, and input/output current measurement and certification for EVs or energy storage devices.

Deepening Roots in Energy Technology, Moving Toward All-Around Testing Solutions

Chen Tech stated: “The debut of the HCM-1000 Series symbolizes Chen Tech’s determination to extend its reach from battery testing equipment into the field of precision instrumentation. During this critical period of energy transition, precise data is the foundation of technological innovation. The HCM-1000 will help customers shorten verification time and enhance system safety when developing energy storage and EV battery systems.”

Increase Data Recording Frequency / Expand System Scalability with No Burden!!

As the revolution of battery production technology, the adaption of new technology becomes one key factor for battery manufacturers while evaluating and purchasing manufacturing or testing equipment. Among all, improvement of data recording frequency is critical. In addition, the number of channels controlled by a single computer is expected to increase accordingly.

Take advantage of the robustness of CANBus interface on command synchronization, it is currently applied on the majority of our product series to connect equipment and computer, such as PBT Series, MCL2 Series, MCL Plus Series, and MCF Plus Series. However, as the demand of rapid data recording, the number of computers and communication units will increase accordingly. To enhance productivity, we now integrate Ethernet interface into the existing solutions. Compared to sorely CANBus interface, a combination of CANBus and Ethernet solution allows one computer to control max. 512 testing channels simultaneously, which is 3 times greater than the existing solutions. From now on, the perfect integration of robust CANBus signal control mechanism as well as high-speed Ethernet data recording scheme is realized in CTE products.
