SWG30 SERIES DC/AC single output ring generator • • • • • 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.

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 10µF. To meet VDE0871 level A conducted noise, connect a capacitor with a value >47µF between (+Vin) and (-Vin). PEAK OUTPUT DC CURRENT TYPICAL EFF.
