Air Compressor

[NE-S1] NE-S1 Series

Squirrel cage motors, suspended solids collector, cream solder printing machine of air transport, food packaging machinery, HVAC control,
FAN, PUMP, BLOWER extra entry-level inverter suitable for machine

phase 200V class 0.2 in 2.2KW ~
3-phase 200V class 0.2 ~ in 2.2KW
3 phase 400v level: 0.4 ~ 4kW


Simple machines suitable for entry-level inverter

1. The space saving

Side by Side installation is possible by the installation space can be utilized effectively

. 2. Simple operation

-intensive operation, stop, reset with one button

3. The corresponding global

standards corresponding to international standards ( UL, cUL, CE, corresponding) to the respective standards of the c-Tick
sink an input of the control circuit / logic circuit corresponding to two of the source

4. the network corresponding

to a communication port corresponding to the RS485 standard Modbus RTU-mounted

as 5. options customization available

can be customized according to customer usage of the device

6. the energy savings realized

automatic energy-saving features of the operating controls so that at all times the minimum power consumption
is possible to simplify the external circuit computation / delay of the signal output terminal
keypad / terminal switching function
simply switching possible by the on / off frequency of command processing, intelligent input terminal of the operation command buffer
a second control function: two kinds of by switching the motor to a single inverter operation possible
3-WIRE function: driving and push-button switches to a halt when using the automatic return of such contacts valid
analog input disconnection detection function:
frequency reference output to an external frequency reference signal to output a disconnection when disconnection missing

features Hitachi's low-voltage inverter

1. trip faithful suppression
    starting torque 0.5 Hz 200% or more and a drive overcurrent and overvoltage suppression by the high-speed current control, with
    enhanced and 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.
