去年，基岩自动化宣布其工业控制系统（ICS）是the first ICS to meet the Military Standard 461 and International Electrical Commission 61000 standard for electromagnetic pulse (EMP) resistance。

而回顾,从基岩Automati释放on last year, I asked Albert Rooyakkers (founder and CEO of Bedrock Automation) what good it was to the user if the controller was EMP protected, but not the rest of the system it relies on for power. At the time, Rooyakkers answered: “The immediate issue for an owner/operator is to assure a safer and more orderly shutdown of a process in the event of an accidental or intentional EMP strike, and this is what an EMP-hardened control and safety system can provide. Plus, since ICSs are typically installed with an expected service life of 20 to 40 years, the automation technology event horizon should anticipate as much as possible as far into the future as possible. Solving EMP now puts an owner/operator ahead of a likely curve of cyber defense issues.”
One year later, Bedrock Automation announced that it has now extended its controller EMP resistance to both its secure power supply (SPS.500) and lithium uninterruptible power supply (UPS.500). As with the controller announcement last year, the power supply and UPS have achieved compliance with Military Standard 461 and International Electrical Commission 61000 for EMP resistance.
“As the threat of an EMP event becomes increasingly understood, our users can have greater confidence that their operations will not be interrupted. This is the kind of comprehensive cyber protection that is essential for both performance and safety as global industry becomes increasingly digitized,” said Rooyakers in the announcement.
National Technical Systems, an independent military and industrial testing firm, conducted test RS105 for radiated susceptibility to a transient electromagnetic field. The power supplies were tested separately, each receiving repeated 50,000 V/m nanosecond EMP strikes that emulate the energy of a high altitude electromagnetic pulse (HEMP), as would be created by an atmospheric nuclear detonation. The Bedrock power supplies performed without error and without consequential damage during and after the test.
像BedRock Automation的控制器一样，SPS.500安全电源具有BedRock的Deep Trust网络安全身份验证和用于诊断和安全以太网通信的机上智能。使用90-264 V AC主电压50/60 Hz输入，它包含在NEMA 4X密封的铝制外壳中，提供单个或冗余的功率。它的输出高达500瓦是可配置的，可配置21至28伏。据该公司称，任何PLC，SCADA RTU，PAC或DCS的用户都可以在内部或外部外壳，工厂和恶劣环境中的任何地方或外部外壳进行改装。
The UPS.500 uninterruptible power supply is designed to be the battery backup for the Bedrock OSA (Open Secure Automation) platform, but can be used to supply 24 V DC 12Ah of power to any industrial control system. An onboard secure microcontroller controls the Li-ion polymer battery cell-by-cell, augmenting the high density, rapid charging, extreme temperature tolerance and extended life that characterizes Li-Ion technology. It is also protected by a sealed aluminum enclosure rated for IP66/67.
