energy meter
- Product Details
- Company Profile
The GSD7666 is used for a wide range of applications, due to an improved dynamic range allowing a basic current of 5 Amp while retaining a maximum current of 80 Amp and extended functional features. It is a compact and keypad-based design in a B58565 standard housing and maintains the rugged RF immunity withstand of 30V/m and IP54 rating, allowing it to be installed in harsh environments.
