Danfoss Electronics MCD 100 Features and Benefits

VLT® Soft Start Controller MCD 100

MCD 100 is a cost eective and extremely compact soft starter for AC motors up to 15 HP. Due to a unique semiconductor design
MCD 100 is a true “t and forget” product. Selection can be made on the basis of the motor power—exactly as with traditional
contactors.

The new range features three dierent products, MCD 100-001
(2 HP), MCD 100-107 (10 HP), and MCD 100-011 (15 HP). In fact
the MCD 100-001 is the world’s smallest soft starter rated up
to 2 HP. All sizes are rated for line voltages up to 600 VAC.

MCD 100 products provide timed voltage ramp up and down.
Ramp time can be individually adjusted with rotary switches
from 0.4 to 10 seconds. The start torque can be adjusted from 0
to 85% of the direct on-line torque.

Application

MCD 100 is an ideal alternative when starting smaller AC
motors direct on-line or with a star-delta starter. The typical
applications would be soft start / stop of conveyor systems,
pumps, and soft start of smaller compressors, for example
scroll or reciprocating compressors in air-conditioning units.
MCD 100 products can be installed side by side and with or
without a line contactor. Motor protection must be installed
separately. Short circuit protection can be achieved by the use
of fuses or a circuit breaker.

Perfect

match for:

- Pumps

- Fans

- Compressors

- Mixers

- Conveyors

- and many more

Benets with MCD 100 over traditional small soft
starters

 A robust semiconductor design – selection can be based on

motor power which ensures easy selection. It can be used for an
almost unlimited number of starts per hour without derating.

 A universal control voltage (24-480 VAC / VDC)—simplies

selection and keeps stock at a minimum.

 A “t and forget” contactor design—simplies installation

and reduces required panel space.

 Digitally controlled rotary switches—secures precise settings

and simplies installation.

 Ratings for heavy duty as standard—simplies installation

and reduces the risk of breakdown.
