PowerLOK quality assurance procedures—sourcing, manufacturing, testing, and commissioning—each contribute to a more reliable rack PDU. From the design phase to product delivery, PowerLOK ensures a long-lasting, reliable product. Safety and dependability are top priorities for PowerLOK rack PDUs, and that’s why we subject our products to accelerated life testing, including; voltage cycling, exposure to high and low temperatures, and resistance to vibration.
