The energy-saving power relays will belaunched this June. The relays are small dimensions of 30 x 36 x 40 mm and anoperating power of 1.88 W. It will contribute to the downsizing and energysavings of high-current or inverter-based equipment.

 

Osaka, Japan - Panasonic Corporationannounced today it introduces the industry's smallest* power relays"HE-SRelay", which have realized one of the industry's lowest operating powerlevels*. HE-S Relays can safely cut off abnormal currents that may occur whenpower conditioners for photovoltaic power generation or power storage system,industrial equipment such as elevators, and stationary EV chargers are inoperation. They will be available on the market starting in June 2015.

 

* As multi-contact, high-capacity relayswith a capacity of 35 A or greater. As of June 1, 2015 based on Panasonicresearch.

 

Product name	HE-S Relays
Release date	June 2015
Price	To be discussed separately based on the quantity

 

Downsizing, weight reduction, and energysavings are demanded of power conditioners for photovoltaic power generation,storage battery and various industrial equipment systems. The power relays areused for cutting off inverter current safely in case of a failure in theseequipment systems and there are growing needs for downsizing and reducedoperating power. Panasonic has developed the industry's smallest* HE-S Relaysthat employ the mirror contact structure, thus achieving one of the industry'slowest operating power levels*. HE-S Relays will contribute to the downsizingand energy savings of equipment and systems that require high-capacity control,such as power conditioners for photovoltaic power generation or power storagesystem, elevators, uninterruptible power supply systems(UPSs), and varioustypes of industrial equipment.

 

Features   

 

1. The industry's smallest package* canreduce the footprint, contributing to the downsizing of the equipment.

Dimensions: 30 (L) x 36 (W) x 40 (H) mm

 

2. The coil hold voltage is reduced toapproximately 30% of the rating voltage. One of the industry's lowest operatingpower levels* 1 contributes to the energy savings of the equipment.

Operating power: 1.88 W (at an ambienttemperature of 20℃)

Holding power: 170 mW (at an ambienttemperature of 20℃)

 

3. The adoption of the mirror contactstructure (conforming to EN 60947-4-1) facilitates the design of safetycircuits.

Welding of contacts can be detected safely.

 

Applications

 

Safe cut-off applications of AC mainselectricity in power conditioners for photovoltaic power generation or powerstorage system

Safe cut-off and power control applicationsin industrial equipment such as elevators and UPSs (uninterruptible powersupply systems), as well as stationary EV chargers
