POWER SUPPLIERS
For type approval reasons, this product should not be operated with unapproved
supplies.
The equipment must be installed so that the IEC connector for the Wall or Rack Mount
can be easily removed and/or the power socket should be readily accessible.
Mains protective Earth should be checked for low impedance (<0.3 Ω).
All mains wiring must comply with local wiring regulations.
POWER SUPPLY OPTIONS
The SDB670 Base Station is available in both AC and DC versions. The AC version
contains an internal Power Supply Unit (PSU), which produces the DC voltages required
in the base station. The DC versions all use 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 SDB670 Base Station is +13.6
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 SDB670 Base Station in an enclosed 19” rack. Together, an SDB670 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 SDB670 Base Station. The voltage range appropriate to the area of use is
selectable on the universal PSU.
SDB670 AC POWER CORD
A 2 m long cable used to connect the AC Mains Supply to the base station, using the
wall mount, or a PSU tray in the rack mount. An appropriate version of power cord,
relevant to the area of use, is supplied with the SDB670 Base Station. Relevant areas of
use are as follows: United Kingdom, Rest of Europe, United States.
