[Discontinued] Automatic AC Switch "ACT-102"

[Discontinued] Automatic AC Switch "ACT-102"

By using this device, you can automatically switch between the inverter output AC and external AC to power the load.

- When the external AC power supply is connected, the load will use the external AC power supply. When the external AC power supply is lost, if the inverter is connected, it will automatically switch to continue using the load. - The input AC cord is directly connected, so it can be used immediately. - Brackets for vertical and horizontal placement are included, allowing for installation to fit limited spaces. - There are fixing brackets on the output side to prevent disconnection, so if disconnection is a concern, it can be secured with cable ties or similar.

Semi-Automatic Switching Pressure Reducing Valve/Device 'Semi-Automatic Switching Semi-O TN-50 Series'

Semi-Automatic Switching Pressure Reducing Valve/Device 'Semi-Automatic Switching Semi-O TN-50 Series'

It can supply gas continuously! A device that switches when one cylinder runs out.

The "Semi-Automatic Switching Semi-O" device divides the gas supply (cylinder) into two series, supplying gas from one series, and automatically switches to the other series when one cylinder is empty. By simply replacing the empty cylinder with a filled one and operating the switching handle, continuous gas supply can be achieved. Since switching can be done with a single pressure regulator, it has become lightweight and compact. It is easy to carry and install, and requires minimal installation space. 【Features】 - Allows for cylinder replacement while supplying gas - Easy operation with a simple tilt of the switching handle - Built-in small check valve at the inlet - No gas will escape from the inlet during cylinder replacement (except for CVN type) - Can be used with flammable gases such as hydrogen since it does not use electricity during series switching - Option for pressure gauge with contacts available For more details, please refer to the catalog or feel free to contact us.
