4KW Variable Frequency Inverters 220V to 220V for single phase motor
EM15 sereis is a new-generation inverter developed independently by EMHEATER, featuring low noise, high performance and multiple functions. It adopts the rotor field-oriented vector control strategy to realize high-accuracy, wide-range speed and torque control of the motor with high reliability, powerful functions.
Products Feature
Support various motor's control mode
Support V/F control, Sensor-less vector control and Closed-loop vector control.
Support several of encoder.
High starting torque character
150% starting torque at 0.5Hz(Open loop vector control without PG)
180% starting torque at 0Hz(Closed vector control with PG)
Support Various keyboard display
The screen of the EM15 series inverter is a two-line display, which can display more than 30 states such as frequency and current etc.
Technical Specifications
| Torque Boost | Auto boost; Manual boost 0.1%~30.0% |
| DC braking | 0.00Hz~maximum frequency (DC braking frequency); 0.0s~36.0s(Braking time); 0.0%~100.0%( Braking trigger current value) |
| Built-in Simple PLC / Multiple Speeds | It realizes up to 16 speeds via the simple PLC function or combination of DI terminal states. |
| Built-in PID | It realizes closed loop control system easily. |
| Auto voltage regulation (AVR) | It can keep constant output voltage automatically when the mains voltage fluctuation |
| Overvoltage/ Overcurrent Stall Control | The current and voltage are limited automatically during the running process so as to avoid frequently tripping due to overvoltage / over current. |
| Rapid Current Limit | To avoid frequently over current faults of the frequency inverter. |
| Torque Limit and Control | It can limit the torque automatically and prevent frequently over current tripping during the running process. Torque control can be implemented in the VC mode. |
| High Performance | Control of asynchronous motor and synchronous motor are implemented through the high-performance current vector control technology. |
| Virtual I/O | Five groups of virtual DI/DO can realize simple logic control. |
| Timing Control | Time range: 0.0~6500.0 minutes |
| Motor Overheat Protection | The optional I/O extension card enables AI3 to receive the motor temperature sensor input (PT100, PT1000) so as to realize motor overheat protection. |
| Multiple Encoder Types | It supports differential encoder, open-collector encoder |
| Protection Mode | Motor short-circuit detection at power-on, input/output phase loss protection, over current and overvoltage protection, less voltage protection, overheat protection and overload protection,etc |
| Running Command Giving | key panel; Control terminals; Serial communication port; You can switch between these giving in various ways. |
| Frequency Giving | There are 10 kinds frequency giving: digital setting, analog voltage setting, analog current setting, pulse setting and serial communication port setting. |
| Programmable Digital Input | 6 digital input (DI) terminals, one of which supports up to 100 kHz high-speed pulse input |
| Programmable Analog Input | 3 analog input (AI) terminals, AI1,AI2 support 0V~10 V or 0mA~20mA input, AI3 support -10V~+10V |
| Model | Power Capacity (KVA) | Input Current (A) | Output Current (A) | Adaptable Motor | |
