SWG30 SERIES
DC/AC single output ring generator
• 30VA of ringer output power
• Short circuit protection
• Operating temperature up to 70°C
• Internal sine wave reference
• Remote ON/OFF control
Measuring just 4.00 x 4.00 x 0.63 inches, the SWG30 design maximizes
efficiency, typically 80% at full load. Operating from any input voltage in the
range 40 to 60VDC, the SWG30 features indefinite short circuit protection and
overcurrent protection features, and has a high MTBF of 300,000 hours
(calculated in accordance with MIL-HDBK-217F) to ensure reliable operation. A
remote on/off control feature facilitates easy systems integration. The SWG30
ring generator has a typical input current of 780mA, and a maximum output
current of 400mA rms, (260mA peak DC current). The series features line and
load regulation of 1% and at full load the maximum output ripple is typically less
than 5V peak-to-peak. The unit has a wide operating temperature range of 0°C
to +70°C and the black coated copper case material meets flammability
standard UL94V-0. The SWG30 has an isolation voltage of 500VDC and an
internal sine-wave reference oscillator.
