Dual Rail Powersupply (8 or 16Watt)
The powersupply unit of the seismic industries modules uses high quality DC/DC Converters to deliver pristine +/-12Volt each 700mA (16Watt).
The unit features two independent outputs with identical specs. This allows you to connect your “dirty” (digital) modules to one rail, while other sensitive modules can be connected to the second/clean power source. Without the need of a second powersupply.
Working state of each rail is indicated by a white LED.
Wallwart adapter is included.
These merchants probably sell this module. Huh?
