VLT® Soft Starter MCD 100
VLT® Soft Starter MCD 100 is a cost effective and extremely compact soft starter for AC motors.
Perfect
match for:
–Smaller compressors for example scroll or reciprocating compressors in air-conditioning units
–Conveyor systems
–Pumps
A true “fit and forget” soft starter for DIN rail mount MCD 100 provides basic soft start and stop function.
■A robust semiconductor design
–selection can be based on motor power which ensures easy selection.
■Can be used for an almost unlimited number of starts per hour without derating.
■A universal control voltage (24-480 V AC/ V DC) – simplifies selection and keeps stock at a minimum.
■A “fit and forget” contactor design
–simplifies installation and reduces required panel space.
■Digitally controlled rotary switches
–secures precise settings and simplifies installation.
■Ratings for heavy duty as standard
–simplifies installation and reduces the risk of breakdown
