MAGNETEK SERIES 4 HAS
ARRIVED!
Continuing the long line of reliable and cost effective
variable frequency drives for overhead cranes and hoists,
Magnetek has just released for purchase the Series 4
adjustable frequency crane control.
As most of you know, Engineered Lifting Systems only
provides Magnetek controls for both new cranes, and
modernizations. Well after the initial cost of a project,
Magnetek drives provide repeated performance that is easy to
check, and easy to adjust. There is just not a better VFD on
the market than Magnetek.
The above pictures show the
improved access to the drive without removing the keypad as
on previous drives. Link Software will allow laptop
interface with the drive.
Building on the successes of the Series 2 and Series 3
drives, the Series 4 provides several key improvements that
users are sure to like.
Load Check II Load Check has been upgraded to
continuously detect hoist overload conditions only allowing
an overload to be lowered. Now Load Check monitors the load
both in acceleration and constant speed, and with the new
auto-setup function allows for no drive pause (tests) which
will help production.
Safe Torque Off Provides a redundant hardware safety
circuit that guarantees motor and brake power are removed
when an E-STOP switch or safety controller opens the drive
input, eliminating the need for external disconnects.
Brake Test This is now a one button test for
checking the brake so in an instant you can verify that the
brake has sufficient torque. You can even remote mount the
button, allowing even faster access to this feature.
We were the first on the
block to get a new Series 4 in house!
The performance upgrades includes an increase in
performance that will reduce enclosure temperatures. This is
5-50% lower energy loss than the Series 2, and typical 15%
more efficient than the Series 3. The latest generation IGBT
power modules are capable of four times more thermal cycles.
This means the drives are smaller than the Series 3 drives,
most noticeable in the larger drive sizes. The new drive can
tell you the amount of remaining IGBT so that you can
schedule drive replacement before drive failure, that’s
smart!
Now I have only listed a few of the improvements, but if you
have any questions just call me direct. Engineered Lifting
Systems is looking forward to using these new drives on your
next project!
