3-Phase sinusoidal output voltage
Filtered input/output
Cooling by high quality internal fan
Compact construction
Full electronic protection
Rugged, field-proven design
Cost-effective design

This rugged modular DC/AC inverter system uses microprocessor controlled, field-proven technology to deliver 3-Phase, 1000VA
continuous output power with pure sine wave output voltage. A new design topology simplifies the circuitry and enables a significantly
more compact construction, lower weight, lower cost and higher MTBF than earlier designs. The standard 3-phase outputs are
208Vrms, 380Vrms or 400Vrms (L-L) at the required frequency. Phase-to-neutral voltages can also be used: 115Vrms, 220Vrms or
240Vrms. The input and output are filtered for low noise. Cooling is by high quality built-in fans, which draw air into the unit and the
exhaust exits at the rear of the unit. Full electronic protection, generous design headroom and the exclusive use of components with
established reliability also contribute to high MTBF. The unit is manufactured at our plant under strict quality control.
