POWER SUPPLY OPTIONS
The SDB680 Base Station is only available as a DC version, which uses an external DC power
source. The PSU tray can be used to supply the DC voltage required.
The switch mode supplies used in the wall mount and rack mount ancillaries are able to accept
mains AC voltage in the range of 85 V to 265 V @ 1.9 A, 47 Hz to 63 Hz. The output from the
switched mode power supply to the SDB680 Base Station is +14.0 Voltage Direct Current (VDC).
PSU TRAY
The PSU Tray can be either a 1U or 2U rack tray with a front panel and is designed for use with an
SDB680 Base Station in an enclosed 19” rack. Together, an SDB680 Base Station and the PSU
Tray occupy a total of either 3U or 4U of rack space.
The tray is supplied complete with a universal power supply, which can accept an IEC input of
100 V to 240 V AC (Voltage Alternating Current), at 50/60 Hz suitable for a single SDB680 Base
Station. The voltage range appropriate to the area of use is selectable on the universal PSU.
