Don't rely on flimsy AC adaptors and commercial power for the equipment at your site. Use your existing -48 VDC power plant to power your +12 and +24V equipment.
The 12/24 Power Supply from DPS Telecom provides power to six +12V outputs and an optional six +24V outputs. There's a separate fuse for both inputs and one for every two outputs, ensuring that if a fuse blows, it won't interrupt function of other equipment connected to the power supply.
The unit's dual power inputs ensure you won't have to worry about a power failure knocking out your site's sensors. If a single -48 VDC power source fails, your equipment connected to the 12/24 Power Supply won't.
