characteristics 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 a strong reinforcement the operation function is realized.
※ 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.
