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.
