SWG30 SERIES
DC/AC single output ring generator
* * * * * 30VA of ringer output power Short circuit protection Operating temperature up to 70C Internal sine wave reference Remote ON/OFF control
[ 2 YEAR WARRANTY ]
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 0C to +70C 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.

Notes
1 2 3 4 The SWG30 can operate up to 70C as long as the maximum case temperature does not exceed 85C. The output loading power factor should be greater than 0.85. Measured under resistive load condition at nominal input voltage. All models are available with the suffix `/P' e.g. SWG30-48S75C01/P. Models with the suffix `/P' have the same specifications as their corresponding models, except the remote on/off control logic is reversed. Peak output DC current is the DC biased current flowing through the output. Maximum duration is 1 second. FG pin (pin 5) must be connected to +Vin or -Vin (pins 3 or 4) directly or through a capacitor greater than 10F. To meet VDE0871 level A conducted noise, connect a capacitor with a value >47F between (+Vin) and (-Vin).
