EM700-P series fan and pump dedicated inverter

Product Introduction

The EM700-P series fan and pump inverters utilize an advanced vector V/F algorithm. While maintaining the ease of use of V/F algorithms, they offer performance equivalent to that of vector algorithms, including greater low-frequency torque, high speed stabilization accuracy, and fast response. The multi-line data keypad offers simple operation and a wealth of features, making it incredibly easy to use.

Function Introduction:

1. Output power range: 0.75KW~800KW.

2. Supports various V/F controls including linear V/F control, square V/F, multi-point V/F, etc.

3. Multi-pump control: Adapt to one-to-many water supply cards to achieve constant pressure water supply circulation soft start.

4. PID process control: built-in powerful PID control, sleep, wake-up, feedback overvoltage protection, undervoltage protection, etc.

5. PID setting value: You can set the PID setting value directly by using the up and down keys without entering the parameters.

6. Intuitive setting of water supply pressure: PID water supply pressure setting is no longer a percentage, but MPa, which is convenient and intuitive.

7. Motor ground protection: Real-time monitoring of whether the motor is grounded and whether the output is equal, to provide all-round protection for the motor.

8. Speed tracking and instantaneous stop without stopping: The fan can be equipped with a motor speed monitoring card to monitor the motor speed and achieve smooth start-up. After a momentary power outage, it can automatically restart without impact when the power is restored. It is especially suitable for important occasions such as gas furnace fans.

9. Rich expansion cards: can adapt to a variety of input and output terminal expansion cards, relay output expansion cards, etc.

10. Communication: Stable RS485 communication, compatible with isolated 485 communication card, and strong anti-interference ability.

11. Parameter backup and restore: After the user sets the parameters, they can be backed up and restored with one click.12. Display function: Full Chinese keyboard operation display, can simultaneously display frequency and current, pressure, etc., can customize the display items. No manual is required for easy debugging.

Applications:

Applications such as fans, water pumps, fire inspections, etc.
