Sometimes called switchboard mats, these nonconductive mats protect against shock by preventing the worker from being grounded if an electrical discharge occurs. These mats are used in high-voltage areas where electrical fuse boxes, transformers, or high-voltage boxes are placed. View the TI High-voltage power distribution box block diagram, product recommendations, reference designs and start designing. Our portfolio of HV PDUs enables controlled power flow. Presenting wide range of Power Distribution enclosure solutions. The nVent HOFFMAN Power System is specifically developed for power distribution panels for indoor applications, and is based on wall mounted and floor standing enclosures which makes the system compatible with all existing. The High Voltage Power Box combines the functionality of an Onboard Charger (OBC), a DC/DC converter and a PDU (Power Distribution Unit). The OBC is the interface between the car and the public grid. It converts the energy from the network grid AC (Alternative Current) source to DC (Direct Current). High voltage distribution box is the control part of EV power supply, which has the functions of power distribution, current measurement, short circuit protection, charge and discharge control, pre-charging, manual emergency stop and insulation testing port. Suitable for various environments, they meet rigorous safety.
