INVT Goodrive300 EPS special inverter

Introduction:INVT/INVT Goodrive300 EPS special inverter is customized and developed based on INVT's high-performance vector inverter GD300 hardware platform, with mains synchronization function, widely used in EPS power supply, shore power supply, fire emergency power supply and subway, airport, hospital, large shopping malls and other municipal public facilities power supply system special inverter.

Features:

Mains genlock control

The input voltage is tracked and detected through the mains synchronization terminal card, and the output voltage of the machine is consistent with the power grid at any time, and the positive and negative sequence status of the input power supply of the inverter can be viewed through the function code;

Output phase shift control

The phase shift caused by the transformer can be automatically compensated by detecting the voltage phase at the output end of the transformer, or the compensation angle can be manually set through the function code to compensate;

Closed-loop feedback control of output voltage

Closed-loop feedback control of EPS output voltage to improve the control accuracy of output voltage;

V/F separation control

V/F separation control can be realized, and the V/F characteristic curve can be changed;

Fast output

The output frequency can be accelerated to a given frequency instantaneously;

It can drive all kinds of motors

Including permanent magnet synchronous motors, high-speed spindle motors, direct drive motors and asynchronous motors.

power	Rated output voltage (V)	Equal to the input voltage, the error is less than 5%
	Rated Output Current(A)	See Ratings
	Rated output power(kW)	See Ratings
	Rated Output Frequency (Hz)	50Hz/60Hz, fluctuation range: <±0.5%
Operational control performance	Control mode	V/F, open-loop vector, V/F separation
	Phase-locked mode	Open-loop phase-locked mode, closed-loop phase-locked mode
	Carrier frequency	When the 1.0~15.0kHz inverter leaves the factory, the manufacturer has set the carrier frequency reasonably. In general, there is no need to change this parameter. When the user uses more than the default carrier frequency, it needs to be derated, and the derating is reduced by 20% for each additional 1kHz carrier frequency
	Automatic reset of inverter failure	It supports automatic fault reset, and can set the number of fault automatic reset times and the interval between fault automatic reset
Protection features	Motor overload protection	Software function code setting
	Inverter overload protection	Model G: 150% rated current for 1 minute, 180% rated current for 10 seconds, 200% rated current for 1 second P type: 120% rated current for 1 minute
	Overvoltage protection	DC bus 800V overvoltage
	Undervoltage protection	DC bus 350V undervoltage (first undervoltage point), support undervoltage warning output (relay terminal output) Support second undervoltage point protection (default value 250V)
	Input and output phase loss protection	Inverter main circuit input and output phase loss protection (optional)
	Phase detection protection	Mains synchronization card detection signal, input phase loss (UIPL), output phase loss (UoPL), input out of order (UIPE), output out of order (UoPE) protection
Terminal function	Analog inputs	1 x 0~10V or 0~20mA input
	Analog output	1 x 0~10V or 0~20mA output
	Digital inputs	6 normal inputs, minimum frequency 1kHz, maximum frequency 50kHz
