In recent years, under the global pursuit of ESG sustainable development, governments, organizations and enterprises are facing increasing pressure of "Low-carbon and energy-saving" to avoid excessive depletion of the earth’s resources and promote sustainability. In the context of global ESG sustainable development, the impact of "Low carbon and Energy saving" achieved through power monitoring is particularly significant. Therefore, ICP DAS introduces the Advanced IIoT power meter concentrator-PMC-2841M to help customers quickly establish power monitoring systems that fulfill the requirements of "Low carbon and energy saving".
 
PMC-2841M is built on a more powerful hardware platform. It not only retains the core features of the original PMC series products (such as monitoring power usage of equipment and machines via a browser, offering comprehensive IF-THEN-ELSE power demand management, supporting a variety of power meters for different requirements, and providing instant message notification, etc.), but also includes enhanced IoT security mechanism. These upgrades significantly bolster the security of the power monitoring system and strengthen its network connectivity with IoT cloud platforms. Below are the security features that the PMC-2841M offers.

Network Security：The PMC-2841M supports VPN communication with 4 protocols(PPTP, L2TP, OpenVPN and SoftEther), enabling users to establish secure communication tunnels between PMC and the internet. This VPN functionality helps protect the PMC and its connected power meters from external threats.

System Security：The PMC-2841M utilizes HTTPS encryption to secure communication between the browser and PMC, ensuring that settings and operations on PMC remain confidential. Additionally, SNMP v3 encryption and user management authentication mechanism are provided to safeguard connections between the PMC and IT systems.

Data Security：The PMC-2841M is equipped with a microSD card for data logging operations of the connected power meters. Data log files can be automatically sent to the back-office via FTPS, or users can manually download them by using SFTP, FTPS or web protocols. The transmission of these data log files is protected by TLS encryption to prevent interception or tampering during transfer.

Identity Authentication Security：The PMC-2841M supports Blacklist/Whitelist functionality, allowing users to filter and restrict domain access. It also includes a dynamic blacklist feature that automatically adds IP address with excessive failed login attempts to protect PMC from brute-force password attacks.
