Panasonic Corporation announced what is claimed to be the industry’s smallest power relays which have also realized one of the industry’s lowest operating power levels. The new HE-S Relays can safely cut off abnormal currents that may occur when power conditioners for photovoltaic power generation or power storage system, industrial equipment such as elevators, and stationary EV chargers are in operation. These relays are rated for 35A at 277Vac. They will be available on the market starting in June 2015.
Downsizing, weight reduction, and energy savings are demanded of power conditioners for photovoltaic power generation, storage battery and various industrial equipment systems. The power relays are used for cutting off inverter current safely in case of a failure in these equipment systems and there are growing needs for downsizing and reduced operating power. Panasonic has developed HE-S Relays that employ the mirror contact structure, thus achieving one of the industry’s lowest operating power levels. HE-S Relays will contribute to the downsizing and energy savings of equipment and systems that require high-capacity control, such as power conditioners for photovoltaic power generation or power storage system, elevators, uninterruptible power supply systems (UPSs), and various types of industrial equipment.
Applications are expected to include: Safe cut-off applications of AC mains electricity in power conditioners for photovoltaic power generation or power storage system and safe cut-off and power control applications in industrial equipment such as elevators and UPSs (uninterruptible power supply systems), as well as stationary EV chargers.
