RO-GEN 101

3 Phase Static Inverter
1.2kVA Variable Voltage, Fixed Frequency

The RO-GEN 101 is a variable output voltage inverter, producing 0-140V 3∅ 400Hz AC at 1.2KVA from a mains AC input. Its transformer isolated sinewave output and rugged construction make it ideal for service workshops, test facilities and research laboratories.

The RO-GEN 100 converts single phase mains input into three phase 400Hz 115Vac rms. It is ideal for service workshops, test facilities and research laboratories. The input is EMC filtered and power factor corrected. The output frequency is quartz crystal controlled. Efficiency at full load conditions is typically 80%.

The outputs are independent from each other and isolated from the input by transformers. This makes for robust and reliable performance with enhanced safety. Safeguards include over-temperature and two stage overload protection. A 2kVA 500ms surge rating enables the unit to start complex loads that demand high inrush currents. 

The RO-GEN 100 features fixed voltage output and is equipped with a temperature controlled fan. 

All units are manufactured on site in accordance with Roband’s approved Quality Management System.
