MC series solid state phase converters (or electronic phase converters ) offer "big drive" features for adapting standard or premium efficiency three phase motors to adjustable speed operation -  from a single phase  power supply!  Utilizing the latest microprocessor and advanced IGBT power conversion devices, these high performance controllers program and read-out in plain English terms, eliminating the frustration and time involved in looking up confusing coded symbols. Complete, rugged steel enclosures for NEMA 1 (IP31) or NEMA 4/12 (IP65) service do not require additional enclosure protection as with many plastic-housed compact drives. Built-in thermal overload protection reduces additional costs. Heavy-duty wiring terminals, accessible via three conduit openings on the bottom of the housing, speed installation time and costs.

These electronic phase converters are rated  for 240v single phase input, and will operate a motor at full rated HP.

Features

-  Three preset speeds / Scrolling speed control
-  Adjustable acceleration and deceleration times
-  DC braking - time and voltage adjustable
-  Forward/Reverse
-  Back-lit LCD display
-  Speed reference signal. (Choice of potentiometer), (0-10VDC) or (4 - 20 mA) inputs
-  Analog output signal 0 - 10VDC speed or load
-  Two auxiliary contacts: One from C relay and one open collector output
-  Slip compensation
-  Constant torque - with adjustable current limit

SCM / SCF Series - Single Phase Input / Three Phase Output

- Replaces your magnetic starter -

SCM / SCF Series for installation in existing motor control panels. (or can be mounted in a separately purchased NEMA 1, vented enclosure.)
 
Single phase input / 3 phase output
Output HP Input volts Cat # Dim. Key
0.5 120/240v SM105S A-1
1.0 240v SM210S A-2
1.5 240v SM215S B-1
2 240v SM220S B-2
3 240v SM230S B-2
5 240v SF250Y C-1
7.5 240v SF2150 D-1
10 240v SF2200 D-1


SCM / SCF Series drives are available for 0.25 HP when connected to a single phase input of 120v (output voltage is still 230v with 120v input), or 10 HP maximum connected to a 240v single phase supply.

These solid state phase converters/speed controllers are compact (See dimension key), yet loaded with features usually only associated with expensive drives! Remove your equipment's existing magnetic starter, and mount the SC / SCF series drive in its place. Alternatively, order an optional vented enclosure along with the drive. Connect your existing (Stop/Start push buttons or Hand/Off/Auto selector) to the drive's terminal board, power up, and select the drive's operating parameters.

For speed control, use either the SC / SCF built-in miniature buttons, or request a speed potentiometer kit (optional for the SC / SCF drive), mount this potentiometer on your enclosure, and connect back to the drive terminal strip. Nothing could be easier!

Features

-  Seven preset speeds / Scrolling speed control
-  Adjustable acceleration and deceleration times
-  DC braking - time and voltage adjustable
-  Forward/Reverse
-  Speed reference signal. (Choice of potentiometer), (0-10VDC) or (4 - 20 mA) inputs
-  Analog output signal 0 - 10VDC speed or load
-  Can be used with the open collector output to drive an external relay
-  Slip compensation
-  Constant torque - with adjustable current limit
-  48 to 62 Hz input frequency tolerance (ideal for 60 & 50 Hz applications)
