Panasonic Power Distribution Unit Solutions

Panasonic’s DW Relays are small and ideal for Power Distribution Units. PDUs can contain dozens of densely mounted relays per board. The small size of the DW Relays allows for efficient use of board space and accommodates airflow between the relays to keep the board cool. The market trend for PDUs, particularly those installed in micro-data centers, will need to be very small and require relays with a small footprint. Next, the DW Relays feature a latching mechanism that saves power as it only requires a short pulse to the coil to remain in the SET position rather than continuous coil power consumption. In addition to energy-saving, this feature lowers the internal heat rise from the relay, reducing the overall board temperature. Also, the DW Relays contain a TV-8 inrush rating which means the relay can handle the large inrush generated by the uninterruptible power supplies or UPS that are common for this application. Finally, the DW Relays offer very consistent ON/OFF switch timing allowing the PDU design to take advantage of zero-cross switching circuitry to minimize the inrush across the contacts.
