6V PSU: your Hub 2 on a 6 or 12 volt source
Do you want to power a Hub 2 or Hub 2 Plus from a battery instead of the mains? The Ajax 6V PSU makes this possible with a wide input of 4.2 to 16 volts.
The 6V PSU (type A) replaces the standard 110/230 V board in the housing of the Hub 2 or Hub 2 Plus. This allows the hub to run for years on an external 6 or 12 volt battery, without a connection to the mains. Useful for building sites, vacant properties, holiday homes, boats and campers. If you want a wider input up to 32 V, see the 12-24V PSU (type A).
