3-phase sine wave DC/AC inverter delivering 3 KVA for industrial apps

Absopulse Electronics CTP 3K Series industrial quality inverter system delivers 3kVA, output power.

Standard CTP 3K systems deliver 208Vrms, 380Vrms or 415Vrms continuous symmetrical 3-phase output at 50Hz, 60Hz or 400Hz from inputs of 24V, 36V, 48V, 25V or 250Vdc. Other input and output options are available on request.

The CTP 3K Series is comprised of four fan-cooled modules in a 6U, 19" rack-mount or chassis-mount assembly. Three of the modules perform the DC/DC voltage conversions, the fourth module the DC voltage to 3-phase AC voltage conversion. The modular nature of this design facilitates on-site maintenance.

This rugged inverter features high efficiency, tight output regulation and less than 5% total harmonic distortion at full load. It has full electronic protection including current limiting, short circuit protection, surge protection and thermal shut-down with automatic recovery. These, as well as the exclusive use of components with established reliability, make the system suitable for critical applications.

The CTP 3K meets international safety approvals C22.2 No.107.1-01, UL458 and EN60950 and is filtered to meet EN55022 Class A as a minimum. Options include remote shutdown, output fail alarm (Form C), as well as full rugged and conformal coating for operation in extreme environments.

The ideal applications of this inverter system are industrial automation, aviation ground support equipment, utility and alternative energy applications.
