1.1kW – 500kW  /  1105 Inverter  

 

Overview

 

 

The 1105 digital AC inverter provides flexible, efficient and cost-effective solutions to a range of control needs.  It combines the latest IGBT-based PWM and digital-signal processor technologies with a revolutionary, patented digital-current regulator to deliver optimum performance, full programmability, and simplicity of operation. Compact and rugged, the inverter comes as an open chassis or in a NEMA 4 enclosure. Either type can be foot-mounted to a sub-plate or flange-mounted through a cutout, to dissipate heat outside an enclosure.

 
     

 

 

 

 

Performance Flexibility:

The 1105 offers performance capabilities to suit a broad range of applications where variable-frequency AC or conventional DC inverters are normally used. It can be configured for either constant-load, variable-load, or extended-load applications. A variety of general-purpose and application-engineered software options provide features optimized for specific customer requirements, such as blower and pump motors.

 

Digital Setup, Easy Operation:

The keypad and liquid crystal display provide a simple interface for setting and viewing operating parameters and diagnostics. All controller settings are made digitally through the keypad. Readouts and fault messages are displayed in plain language. A help feature provides on-line assistance at the touch of a button.

 

Power Quality:

The 1105 includes a built-in link choke that provides near-unity overall power factor at all motor speeds as well as low harmonic line currents.

 

Protection and Advanced Diagnostics:

The 1105 monitors its operating conditions and provides a comprehensive set of overload, short circuit, and other protective features. Faults are displayed in plain language along with the operating conditions at the time of occurrence. A log stores the last three faults as well as the buss voltage, motor current, output frequency, operating mode, and time of the most recent fault.

 

Serial Connectivity:

The 1105 features a fully-isolated EIA RS-422/485 serial interface that allows a process control computer, building automation system, or other host computer to set up, monitor, and control the drive using an ANSI standard protocol. An EIA RS-232 port is also available for direct connection to most types of personal computers. Optional DF1 and RTU protocols allow direct connection to Allen-Bradley and Modicon programmable controllers.
