Automatic power transfer solution.
AMF (Automatic Mains Failure) Panels are intelligent control systems that automatically manage the transition between grid (mains) power and generator power during a power failure. When a mains failure is detected, the AMF panel sends a signal to start the generator and transfers the load seamlessly, ensuring continuous power supply.
Once mains power is restored, the AMF panel switches the load back to the mains and shuts down the generator automatically. VRH AMF panels are built using high-quality components and designed for reliability, safety, and efficiency. They are widely used in hospitals, data centers, industrial plants, and commercial buildings where uninterrupted power is critical.

Reliable Power Distribution.
DCDB (Direct Current Distribution Board) is a crucial component in solar photovoltaic (PV) systems, designed to manage and distribute DC power from the solar panels to the inverter. It provides a centralized point for the integration of various protective devices, such as fuses, surge protection devices (SPDs), and circuit breakers, ensuring safe and efficient power flow.
DCDBs are engineered to handle different voltage levels and current capacities, making them suitable for residential, commercial, and industrial solar installations. The enclosure is typically weatherproof and durable, enabling outdoor and rooftop applications. With high reliability and ease of maintenance, DCDBs enhance system performance and safety compliance.

Protects Against Voltage Surges.
LSPU (Lightning Surge Protection Unit) is a safety device engineered to protect electrical and electronic equipment from transient overvoltages caused by lightning strikes or switching operations. It works by diverting the excess surge energy away from sensitive loads and grounding it safely, thereby preventing potential damage to connected systems.
LSPUs are commonly installed in solar PV systems, telecom infrastructure, industrial panels, and building power distribution systems. Their robust construction and high discharge capacity make them ideal for use in outdoor and high-risk environments. These units comply with international safety standards and are essential for improving system reliability and extending the lifespan of electrical assets.
