DM650 Narrow-band High-speed PLC project creates environmental friendly smart grid
 
DM650 can support 350 KHz (80kHz band width) and 270/421 KHz (30kHz band width) at the same time. It inherits the compatible transition route to advance quick development of smart grid to narrow band.
Our DM650, as the first environmental friendly gird product, its speed can be up to 20 kbps, static power consumption as low as 8.5 mA@ 3.3V and harmonic suppression over than 70 db, far ahead of competitors.
DM650 is an epoch-marking product to open the new future of green smart grid.
DM650 adopts large dynamic range, low noise and strong adjacent band suppression switching capacitor filter technologies with its harmonic suppression ability much higher than domestic similar products.
