AC Drives – – AC Drive Controllers

AC Drives and AC control circuits are considered to be part of the high tech electrical controls market. Even the more straightforward AC controllers involving contactors, starters, timers, metering and relay logic can become quite technical.

Knowing what is going on with the demands on your electrical machinery through firstAC Drives hand knowledge and visual inspections can save you a lot of headaches and downtime. Therefore, the importance of using solid state monitoring devices that send valuable information to your electrical maintenance office or provide you with visual information on the door of the cabinet cannot be underestimated in keeping your equipment up and running & making money.

A customized AC Controller from an industrial controls supplier, like Joliet Technologies, can provide you with all the required components from, programming of the PLC, touch screen controls, simple starter or contactor cabinets, all customized for your unique needs.

All down stream electrical auxiliary equipment controls, such as hydraulic pumps, air pumps, solenoid vales, exhaust fans and blowers can be packaged in a single enclosed control system.

For MCC (Motor Control Center) AC Controller applications, Joliet Technologies can add interconnect wire harnessing, PLC sections, and help with engineering and commissioning.

From the basic starter panel, to the complex control system, Joliet Technologies is prepared to work with you, to provide the controls needed to improve the preformance and production of your manufacturing machinery needs.

AC DRIVES – PRINCIPLES OF OPERATION

AC ControllerAdjustable frequency AC motor drive controllers frequently termed inverters are typically more complex than DC controllers since they must perform two power section functions, that of conversion of the AC line power source to DC and finally an inverter change from the DC to a coordinated adjustable frequency and voltage output to the AC motor. The appeal of the adjustable frequency drive is based upon the simplicity and reliability of the AC drive motor, which has no brushes, commutator or other parts that require routine maintenance, which more than compensates for the complexity of the AC controller. The robust construction, and low cost of the AC motor makes it very desirable for a wide range of uses. Also, the ability to make an existing standard constant speed AC motor an adjustable speed device simply by the addition of an adjustable frequency controller creates a very strong incentive for this type of drive.

AC CONTROLLER TYPES

A number of different types of AC motor controllers are currently in common use as general purpose drives: Pulse Width Modulated (PWM), Current Source Input (CSI), and the Load Commutated Inverter (LCI). Each type offers specific benefits and characteristics but the PWM type has been selected by Fincor Electronics as offering the best combination of simplicity, performance and economy for general purpose applications.

Popular Products Series

SIEMENS SINAMICS G130 Chassis Units

SINAMICS G130 chassis units have been designed for variable-speed drives in machine building and plant construction.
They have been specially tuned to the requirements of drives with quadratic or constant load characteristics with medium performance requirements without regenerative feedback.

Mitsubishi F740 Series Frequency Inverter

The FR-F700 Series was launched in 2004 as the successor to the FR-F500 Series VFD. With growing market demands for energy saving inverters in building automation, water processing and HVAC industries, the FR-F700 was able to exceed power-saving expectations in fan and pump applications by incorporating “OEC” (optimum excitation control) which combined maximum drive utilization with minimal power consumption.

6RM80 SINAMICS DCM Cabinets

We provide the assembled version of 6RM80 product, and all the accessories are from the official Siemens, which are 100% tested and strictly tested before delivery.
Please consult our sales department for price.

ACS800-104/-104LC – inverter module

These 3-phase inverter modules have the flexibility to fit into your own cabinets. They can be parallel connected to produce higher powers. Built-in redundancy allows you to run the drive at partial load, even when one of the modules is not operating. The inverter modules include capacitors that smooth the voltage of the DC busbars in multidrive configurations. Available as air and liquid-cooled variants.

ACS800-04 – single drive modules

The single drive modules variant ACS800-04M offers more possibilities. Including normal bookshelf mounting and flat (sideways) mounting. This improves installation into cabinets with a shallow inner depth. Frame size R7 also offers a variant with motor connections available from the bottom of the module. Giving you the possibility of a narrower cabinet for relevant installations.
