  • Intelligent Individual Control PDU Power Strip

    Intelligent Individual Control PDU Power Strip

    Raritan intelligent PDUs (iPDUs) allow you to control the power of a single PDU or a group of PDUs, down to the individual outlets. Instead, you can manually or programmatically power your intelligent PDUs. With up to 21 intelligent programmable breakers with a rating up to 125 amps, the SMART PDU I- type, with its 1U design, is compact, hot swappable, and built to meet safety standards. Grow your network, not your headaches. The range consists of four models offering various levels of power monitoring and power switching features, and can be manufactured as single, dual or 3-Phase with a choice of socket types and mains lead. Smart PDU I-Type is a compact 1U DC distribution with intelligent plug-in breakers suitable for applications where individual power and energy monitoring is required for each breaker output. They distribute power from a single input to multiple outputs but lack any form of metering, monitoring, or remote management capabilities. Unlike basic PDUs, you don't need to be physically present in the facility.

  • Why does the power distribution box show that it has power

    Why does the power distribution box show that it has power

    They check the incoming power to ensure it has the right voltage and current. This step keeps your electrical system stable. A power distribution box (also called PDU or distro) directs electricity from a main source to multiple circuits. It acts like a hub or traffic controller, managing power flow to different areas or devices. Using a distribution board the right way saves. A distribution box uses MCBs, RCDs, and busbars to protect circuits, prevent shocks, and ensure safe power distribution in homes and buildings. It contains safety mechanisms like circuit breakers, neutral and ground bars, and wiring. A distribution board (also known as panelboard, circuit breaker panel, breaker panel, circuit breaker, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit.
