Not every installation runs on standard AC supply from an indoor panel. Rasnal's Specialised Deployment range covers two scenarios that sit outside the standard VKP-01 and VKP-03 buying path: DC-powered systems operating on 12 V to 175 V, and outdoor AC installations that need the proven VKP protection performance inside an IP66-rated enclosure built for harsh environments. Both models bring the same energy conversion grounding protection to environments where conventional approaches fall short.
Most electrical protection conversations start from the assumption of a standard indoor AC panel — single-phase or three-phase, wall-mounted, protected from weather and dust. A significant number of real-world installations, however, do not fit that assumption.
Solar farms, telecom base transceiver stations (BTS), EV charging infrastructure, battery-linked systems, and remote surveillance deployments often run on DC supply. Outdoor towers, highway surveillance points, border monitoring systems, and rural industrial facilities need surge protection that can survive rain, dust, temperature extremes, and continuous outdoor exposure.
The Rasnal VKP Specialised Deployment range addresses both these realities directly: the VKP-01-DC for DC-powered installations, and the VKP-01-IP66 for outdoor and harsh-environment AC installations. Both are built on the same digital grounding platform that powers the entire VKP range — energy conversion, equi-potential bonding, low-impedance grounding, and static charge elimination — adapted for the specific demands of specialised deployment environments.
The VKP-01-DC is a digital grounding device purpose-built for DC-powered electrical systems. It extends the Rasnal VKP protection and grounding platform to infrastructure that operates on direct current supply — covering four rated DC voltage levels: 12 VDC, 24 VDC, 48 VDC, and 110–175 VDC (±10%).
This makes the VKP-01-DC relevant for a wide range of systems that are increasingly central to modern infrastructure: solar energy installations, battery storage systems, telecom and network equipment running on 48 V DC, EV charging infrastructure, and industrial control systems operating on lower DC voltage rails.
DC systems face their own set of surge and grounding challenges that AC-rated devices are not designed to handle. Lightning-induced surges, switching transients from inverters and charge controllers, and ground potential rise effects all affect DC infrastructure, and the characteristics of these events in DC circuits differ from their AC equivalents. The VKP-01-DC is specifically rated and validated for DC supply, ensuring the energy conversion and grounding functions work correctly within the voltage and current characteristics of DC systems.
Supports four DC voltage levels: 12 VDC, 24 VDC, 48 VDC, and 110–175 VDC (±10%).
Maximum surge handling capacity of 120 kA at 8/20 µs.
Works on the energy conversion principle — converts surge energy to heat dissipated through a low-impedance ground.
Provides equi-potential bonding across DC-connected equipment.
Eliminates static charge buildup on sensitive DC-powered electronics.
Reduces leakage current through a defined low-impedance path.
No separate grounding rod required for effective operation in most installations.
Maintains stable grounding reference for battery-linked and inverter-connected systems.
Outdoor and remote installations expose electrical protection equipment to conditions that standard panel-mount devices are not rated for: rain, dust, temperature extremes, condensation, industrial spray, and UV exposure. Installing a standard VKP-01 in an outdoor location without the appropriate enclosure rating voids the device's performance guarantees and creates a protection gap in exactly the environments where surge and lightning events are most frequent. The VKP-01-IP66 eliminates this gap by providing the complete VKP protection and grounding platform inside a housing rated to withstand outdoor deployment — no separate enclosure sourcing or custom integration required.
The VKP-01-IP66 delivers the proven Rasnal VKP-01 digital grounding and surge protection performance in an IP66-rated enclosure designed for outdoor and harsh-environment installations. It is rated for single-phase AC supply at 100–275 VAC and provides the same 120 kA maximum surge handling capacity as the standard VKP-01 — the difference is the enclosure specification, which makes it suitable for environments where a standard indoor panel-mount device cannot be deployed.
IP66 is a protection rating under IEC 60529 that confirms full protection against dust ingress and protection against powerful water jets from any direction — the standard required for outdoor industrial enclosures in most applications.
