SWG10 SERIES
DC/AC single output ring generator
[ 2 YEAR WARRANTY ]
Provides 10VA of ringer output power
Output voltage may be adjusted from 0V rms to 80V rms
Amplifies a reference frequency between 15-60Hz
Meets psophometrically weighted noise per BTR2511
Conducted emissions performance meets EN55022 level A
High efficiency 4 quadrant switch mode design
Low profile suitable for rack mount system
Defined to provide modular and on-card ring generator facilities to telecoms
systems, the SWG10 offers a definable output voltage 0VAC to 80VAC at up to
10VA with the frequency being custom defined for the applications.
Undervoltage lockout and overvoltage protection combine with a high MTBF to
ensure reliable operation. The SWG10 is suited to several telecom applications
including PABX, public switch and fibre-in-the-loop.

Notes
1
Sine wave reference: The SWG10 can amplify any sinusoidal reference
signal with a frequency between 15Hz and 60Hz. Thus standard telecom
ringer frequencies, such as 15Hz, 25Hz and 50Hz can be easily output. A
sinewave reference needs to be coupled to the unit with a single 0.1F to
1F (100V) capacitor.
2
Efficiency measured with resistive load,
3
Output voltage range adjust: the output voltage is proportional to the
reference sinewave at Ref-In pin (after external coupling capacitor). The
ringer has a voltage gain of 30.8 (typ.).
4
Remote ON/OFF: The remote shutdown operates on. Open collector sink
of 1mA to shut off.
5
The operating temperature range assumes that sufficient airflow exists to
ensure the case/encapsulation temperature never exceeds +85
o
C. At any
power up, the case temperature should not exceed +70
o
C.
6
The input and output fuses are essential because there is no internal short
circuit or overcurrent protection circuitry.
7
System design should ensure that multiple `receiver lifts' (modems, faxes,
answering machines) do not occur simultaneously to cause peak output
current to exceed the 400mA, 150ms maximum.
8
System design should ensure that `Sine Wave Reference' pin 2 is set such
that Vout never exceeds 80V.
