Bedrock is the first – and still, the only – industrial control system to have received mil-spec level certification for EMP resistance and extends this to its standalone power supplies.  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 consequential damage during and after the test.

The Bedrock SPS.500 standalone power supply can supply 24 V DC 12Ah of power to any industrial control system.  Encased in a NEMA 4X sealed aluminum enclosure, It provides single or redundant power, using 90-264 V AC main voltage 50/60 Hz input. Its output of up to 500 watts is software configurable between 21 to 28 volts. Users of any PLC, SCADA RTU, PAC or DCS can retrofit to the new SPS.500 inside or outside enclosures, anywhere in a plant and in harsh environments

The patented, built-in cyber security works transparently inside the SPS.500 to ensure authentication of its hardware, firmware, software, and communication throughout its entire product lifecycle. While some other standalone power supplies have onboard digital electronics, none offer comparable performance, diagnostics and cyber security in a single product offering. More than 30 diagnostic variables can be easily monitored, trended, alarmed and historicized via SCADA, enterprise and cloud applications securely.

Secure 10/100 Mbit Ethernet IPv4/IPv6 communications also supports an embedded IEC 62541 — OPC Unified Architecture Server. Bi-directional communications enable control, diagnostics and status reporting. Encased in a thick-walled, sealed aluminum housing, the SPS.500 is compliant with IP67 and NEMA 4X standards for resistance to water, ice, oil, and dust. This contributes to its versatility in secure IIoT edge  deployments while reducing installation costs by eliminating the need for separate environmental protection enclosures. The ruggedized footprint of the SPS.500 makes it shock and vibration-proof –ideal for use in extreme environments.  It is securely made in the USA and comes with a 5-year warranty as well.
