3-Phase sinusoidal output voltage
Filtered input/output
Cooling by high quality internal fans
19” rack or chassis-mount
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, 10kVA
continuous output power with pure sine wave output voltage. The standard 3-phase outputs are 380Vrms or 400Vrms (L-L). Phase-toneutral voltages of 220Vrms or 240Vrms can also be used. All output neutrals are internally connected to chassis (GND) in “Y”
configuration. Input modules convert the input voltage to an internal DC voltage, which feeds the DC/AC output module. The high
frequency conversion enables a compact construction, low weight and high efficiency. 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.
