The Niwa Grow Hub is capable of handling input/output voltages either 120Vac or 240Vac. If you plug your Niwa into a 120Vac wall outlet all the four outputs will be 120Vac, if you connect it to a 240Vac wall outlet all the four outputs will be 240Vac. The most common household voltage in the United States and Canada is 120V, however, some growers might have access to a 240V grid. If that’s the case, please make sure all your devices work with 240V.
The advantage of higher voltages is that you will have more power handling capability. For example; your maximum amperage per output is 10A (15A in total for the 4 outlets in total):
- 10A x 120V = 1200W max
- 10A x 240V = 2400W max
