THE SCM SERIES - Sub-micro AC drive with basic I/O
The compact packaging and comprehensive functionality make the SCM and SCL an ideal drive solution for use on equipment requiring variable speed, soft starting or reversing operation. The SCM Series can be used with 3-phase AC induction motors rated from 1/3 HP up to 15HP (0.25 - 11 kW) on voltages from 120V single-phase to 480 V three-phase. The SCL is for 240V single-phase inputs up to 3 HP (2.2 kW).
These easy to use drives are configured and ready to use right out of the box for most simple applications. By simple reprogramming, the SCM and SCL will perform many application specific tasks such as multiple preset speeds, electronic braking and motor jogging to name a few. Like all AC Tech sub-micro drives, the SCM and SCL drives use the EPM memory technology for fast and efficient programming.
The SCL frequency inverter includes an integral line filter to comply with the relevant European Union standards for EMC and RFI levels. These drives are identical in all other respects.
Supply Power: Single Phase: 120, 208, 220 or 240 VAC Three Phase: 208, 220, 240, 400 or 480 VAC (+10/-15%) 50 / 60 Hz
Motors: The SCM is designed to operate standard polyphase induction motors rated for 200, 230, 400 or 460 VAC from 0 to 240 Hz.
Enclosure: IP20 with finger safe terminals.
Standard Features Easy Set-up and Operation: The SCL is easy to use right out of the box or can be customized to meet your specific requirements any one of four convenient ways:
-From the front of the drive -The Remote Keypad option -The innovative EPM Programmer. -A PC using AC Techís free TechLink Software and the EPM Programmer
Motor Thermal Overload: The SCM is an approved motor protection device for single motor applications.
Control I/O: Eleven isolated terminals provide connection for 0-10V or 4-20mA reference, 1 fixed and 3 programmable logic inputs and 1 programmable relay output.
Quiet Operation: Adjustable carrier frequency to 10kHz
Remote Keypad: Simple four wire connection to the SCM for operation and programming of the drive. High-impact plastic and gasket permit installation in NEMA 4X (IP65) environments. (instruction sheet available in Library)
DIN Rail Mounting Kit: Allows easy mounting of the SCM Drive onto standard DIN Rail. (instruction sheet available in Library)
Dynamic Braking Kit: Prepackaged resistor modules with control electronics provide easy mounting within the control cabinet. (instruction sheet available in Library)
AC Line Filters: AC input line filters are available for all sub-micro drives to meet European requirements for susceptibility and emissions of electrical and radiated noise (EN 61800-3 and EN 5501). The filter is designed to mount to the electrical panel and has provisions for mounting the drive directly to the face of the filter.
EPM Programmer: Copy drive programs in 2 seconds using The EPM Programmer! Then just plug the EPM into the SCM Series drive and itís ready for operation. The EPM Programmer also provides full programming capability using the backlit LCD display and file exchange with a Personal Computer. (instruction sheet available in Library)
