A switched PDU is achieved by integrating conventional electrical distribution equipment with a smart control circuitry to enable power passing and digital control in a single device, and it usually contains a microcontroller, current sensing circuits, relay or solid-state. A switched PDU is achieved by integrating conventional electrical distribution equipment with a smart control circuitry to enable power passing and digital control in a single device, and it usually contains a microcontroller, current sensing circuits, relay or solid-state. Smart switches (e. ) turn on at low voltages, enabled by PWM control signals, have a very high current capacity (up to 40A), and extremely low on-resistance (down to 1. These devices are providing high energy capacity of around 3000mJ, enabling them to replace relays. Historically, distribution boxes served as simple protective enclosures housing circuit breakers and fuses to safely divide electrical power. The key aspect in realizing an intelligent. To achieve a distribution system self-healing against power outages, emerging technologies and devices, such as remote-controlled switches (RCSs) and smart meters, are being deployed.
