DC/AC 3 Phase Sine Wave Inverters: 6000VA

The CTP 6K Series is a rugged modular DC/AC inverter system that uses a microprocessor-controlled, field-proven technology to deliver 3-Phase, 6000VA continuous output power.It is a mature design with a track record in numerous applications. The standard 3-phase outputs are 208Vrms, 380Vrms or 400Vrms (L-L). Phase-to-neutral voltages can also be used: 115Vrms, 220Vrms or 240Vrms. All output neutrals are internally connected to chassis (GND) in “Y” configuration. The number of modules depends on the input/output combination.

The unit in the photograph is a typical example of one 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 unit has full electronic protection. The input and output are filtered for low noise. The use of components with established reliability results in high MTBF. Cooling is by built-in fans, which draw air into the unit.
