AFE Regenerative Unit-Nietz Electric Co.,Ltd

Features

The AFE regenerative unit is a compact, total all-in-one solution for low harmonics and/or full regeneration, and is the ultimate choice for power quality and energy savings. It has easy to setup and install, safe to use, parallel usage of multiple units, realize complete current sharing. It is mainly applied in cases where rapid DEC, positioning and brake is needed eg mine hoist, elevator, textile machine, paper-making machinery, centrifugal machine, washing machine, drawbench, proportional action and crown block.

Specifications

Spetifications

Basic performance parameters	Input voltage	3PH 380V±15%
	Input frequency	50/60Hz
	Output voltage	580Vdc-780Vdc
	Carrier frequency	10kHz
	Controllable rectifier power factor	≥ ±0.98 (under rated load, the mains voltage harmonics ＜ 3%)
	Controllable rectified harmonic current	＜ 5% (under rated load, the grid voltage harmonics ＜ 3%)
	Work efficiency	＞ 97%
	Overload capacity	120% rated current overload for 30 minutes, 150% rated current overload for 1 minute
Personalization features	Feedback power view	The feedback power (active power) is represented by a negative number, and the accuracy error ＜ 5% at rated power.
	Rectification/Feedback Distinction	Distinguish between "rectified current" and "feedback current": the rectification direction is positive, and the feedback direction is negative.
	Measurement of feedback power	For example, it can be set to record and check the amount of energy returned within a certain hour, with an accuracy within ±10%.
Input/Output	Digital input	Route 1 (X1-COM)
Input/Output	Digital output	1-channel relay (RA-RC)

Application

It is mainly applied in cases where rapid DEC, positioning and brake is needed eg mine hoist, elevator, textile machine, paper-making machinery, centrifugal machine, washing machine, drawbench, proportional action and crown block.
