“Miniaturization” and “low heat
generation” hold the key to the
spread of clean energy
In order to respond to the risk of climate change caused by global warming, there is a growing movement worldwide to accelerate the spread of clean energy.
For the spread of clean energy, it is necessary to improve power generation efficiency by increasing the capacity. However, this entails an increase in the amount of heat generated.
This results in larger equipment and higher costs due to the introduction of cooling mechanisms, hindering widespread use.
OMRON supports the spread of clean energy by providing products that enables “miniaturization” and “low heat generation” while responding to higher capacities.
OMRON proposes power relays that contribute to “miniaturization” and “low heat generation” while responding to higher capacities. |
01 Miniaturization realized by bidirectional power interruption
Realizes miniaturization by reducing the number of parts
Four conventional 400 VDC relays are used
G9KB
Supported by one 600 VDC relay (50A)
Bidirectional charging and discharging switching is possible.
G7L-X-SI [NEW]
Supported by one 600 VDC relay (30 A)
Bidirectional charging / discharging switching is possible. Breaking all lines is also possible with a single relay.
