Air Compressor

[WJ200] WJ200 Series

Carrier group, Lift (Transverse / running), conveyors, cranes, hydraulic pumps, air conditioners, grinding, tire molding machines, rotary valve,
FAN, PUMP suitable inverters combine high torque, etc.

Single phase 100V class: 0.4kW, 0.75kW
single phase 200V class: 0.1 2.2kW ~
3-phase 200V class: 0.1 ~ 15kW
3-phase 400V class: 0.4 ~ 15kW


Easy to use, high-performance inverter with a simple adjustment

1. Improvement of basic performance

 sensorless vector control with 200% more than in the same notice coke realized at 0.5Hz
AC Induction Motor / PM Motor can be driven as an inverter
 equipped with a motor auto-tuning function the inherent characteristics of more effective and high-performance
 motor to realize constant automatic detection

2. trip inhibition achieved stable operation

 over-current and over-voltage suppression
 DC BUS AVR function during deceleration

3. built-in peripherals

equipped with a Safety Stop feature high reliability due to hardware circuit emergency output disconnect

 all models equipped with the standard regenerative braking circuit
 micro-surge voltage suppression

4. improve ease castle

 dual rating function (heavy load, light load selectable) to reduce costs and improve work efficiency, promote the
 program operation with (simple sequence operation)
top the device makes it possible to simplify the peripheral circuit space savings, contribute to the cost of the control panel
 integrated power monitor function

5. space-saving

Side by Side is possible to effectively utilize an installation space to be installed
3.7KW up to a height equal to the control panel design easy

6. easy maintenance

 by adopting a design life of 10 years to realize long-life parts
 service life, the life warning function with
 a simple replacement of the cooling fan can be
 removable terminal board (simple wiring without screws)

7. realization of the network and the corresponding external port

RS -485 (Modbus-RTU)
 on-board as standard options available
Open Network DeviceNet, CC-Link, CompoNet, Profibus, EtherCAT USB (Mini-B
 connector), RS422 (RJ45 connector) is also standard equipped with

8 parameter setting / confirmation is simple user settings feature

 characteristic of Hitachi low-voltage inverter

1. trip faithful suppression
    overcurrent and overvoltage suppression by high starting torque and current control, with more than 0.5 Hz 200% driven
    by strengthening achieved a strong operating capabilities.
    ※ full-load operation when multiple non-inverter protection IGBT module damaged even if the output short-circuit functions
    employed (Hitachi patented)

2. input signal enhancement
    analog (current / voltage) to increase output monitor (AM / AMI terminal) to an emergency resolution It was equipped with a blocking function.
    Do not leave the built-in CPU (software) on the intelligent input terminals on the middle inverter output only hardware circuitry
    can be blocked.

3. The program operation function

   to download the program to the inverter can be simplified sequence of operation and accelerator operation can be automatic, depending on load conditions
   can be simplified and the host device, a peripheral circuit.

4. The peripheral circuit built into inverter

   was EMC filter and built-in video core to the AC power input, and expanded the internal model of the regenerative braking circuit (BRD).
   (WJ200: full capacity, SJ700: 22Kw or less, L700: 30Kw or less)

5. Micro-surge voltage suppression function

   suppresses the motor terminal voltage control pwm by Hitachi's unique approach to the control pulse 2 times or less of the DC voltage.

6. Simple maintenance

   cooling fan, simple replacement of the smoothing capacitor and the maintenance can be simple wiring without a detachable screw terminal board
   even more easily.

7. Life diagnostics Jobs

   was adopted to realize the long-lived component design life of 10 years, temperatures, and cooling fan motor temperature rise by the lifetime diagnostics
   is life warning signals such as output.

8. The improvement in environmental performance

   within the substrate part of the varnish coating, plating the copper bar to the adoption of the standard has improved environmental resistance.

9. The global response
   suited to the world standards (CE, UL, C-UL ) , and you can respond to an open network of DeviceNet, Profibus etc.
