They offer two voltage ranges: 200…480V AC and 200…600V AC. All voltage ranges will operate at either 50 or 60 Hz. y 1…85 A Range y Built-In Electronic Motor Overload Protection y Built-In SCR/Run Bypass Standards Compliance/Approvals y UL 508 y CSA C22.2 No. 14 y EN/IEC 60947-4-2 y cULus Listed (Open Type) (File No. E96956) y CE Marked (Open Type) per EMC Directive and Low Voltage Directive Modes of Operation Soft Start This method has the most general application. The motor is raised from an initial torque value to full voltage. This initial torque can be adjusted to 15%, 25%, 35%, or 65% of locked rotor torque. The motor voltage is gradually increased during the acceleration ramp time, which can be adjusted from 2, 5, 10, 15, 20, 25, or 30 s. (3…37 A, 2…15 s only) Current Limit Start This starting mode is used when it is necessary to limit the maximum starting current. It can be adjusted to 150%, 250%, 350%, or 450% of full load amps. Start times are selectable from 2, 5, 10, 15, 20, 25, or 30 s. (3…37 A, 2…15 s only) Selectable Kick Start A kickstart, or boost, at the beginning of the start mode is intended to provide a current pulse of 450% of full load current. The kickstart time is adjustable from 0.5…1.5 seconds. This allows the motor to develop additional torque during starting for loads which may need a boost to get initial shaft rotation.

When enabled, the voltage ramp down time can be selected to one, two, or three times the starting time. The motor will stop when the motor voltage drops to a point where the load torque is greater than the motor torque. Description of Features Electronic Motor Overload Protection Phase Imbalance The SMC-3 controller incorporates, as standard, electronic motor The unit monitors for imbalance between phase currents. To prevent overload protection. This motor overload protection is accomplished motor damage, the unit will trip if the phase imbalance exceeds electronically with the use of current transformers on each of the specified limits and a fault will be indicated on the LED. three phases. The controller’s overload protection is programmable, providing the user with flexibility. The overload trip class selection Push to Test consists of either OFF, 10, 15, or 20. The trip current is easily The unit with control wiring can be tested for fault conditions by selected by adjusting the rotary potentiometer to the motor full load using the Push to Test function. Hold down the Reset button for 5 current rating. Trip reset is selectable to either automatic or manual seconds to activate the fault Aux (97, 98) and shut down the SMC-3. mode. To clear, either push the Reset button or cycle control power to the Note: Trip rating is 120% of dial setting. device. Over-temperature Shorted SCR The SMC-3 monitors the SCR temperature by means of internal Prior to every start and during starting, the unit will check all SCRs thermistors. When the power poles maximum rated temperature is for shorts and unit load connections to the motor. If there is a reached, the microcomputer switches off the SMC and a TEMP fault shorted SCR in the SMC-3 and/or open load, the start will be is indicated via LED. aborted and a shorted SCR or open load fault will be indicated. This prevents damage from phase imbalance. Phase Reversal Protection When enabled via a DIP switch, 3-phase input power will be verified LED Description (Number of Flashes) before starting.

No. Identification............ 27 The SMC-Delta™ is a compact, simple to use, solid-state motor controller designed to operate 3-phase star-delta motors wired on an inside-the-delta configuration. This Product Selection.................... 28 star-delta replacer is ideally designed for 6-lead motor applications. It features a built- Typical Wiring Diagrams ....... 29 in overload relay and a built-in silicon controlled rectifier (SCR) bypass contactor on all three phases, allowing a smaller footprint than traditional methods of starting. This Specifications............................ 31 product is designed for many applications including compressors, chillers, pumps, Approximate Dimensions ..... 34 conveyors, and crushers. Modes of operation for the controller are as follows: Accessories (SMC-3 and y Current Limit Start SMC-Delta)................................. 25 y Coast to Rest The controllers are available in 11 sizes: 3, 9, 16, 20, 25, 32, 51, 64, 74, 104, and 147 A. They offer two voltage ranges: 200…460V AC and 200…575V AC.

It can be adjusted for 150%, 250%, 300%, or 350% of full load amps. Start times are selectable from 2, 5, 10, or 15 s. Description of Protection Features Overload Protection Shorted SCR The SMC-Delta has a built-in overload feature. Trip class selection Prior to every start, the unit will check all SCRs for shorts and unit consists of either OFF, 10, 15, or 20. It provides improved protection load connections to the motor. If there is a shorted SCR in the against the damage caused to motors when operated under phase SMC-Delta, the start will be aborted and a shorted SCR fault will be loss conditions. Trip reset is selectable to either automatic or indicated. This prevents damage from phase imbalance. manual mode. As standard, it includes a manually generated trip Push to Test function, LED indication, and N.O. alarm contact. The unit with control wiring can be tested for fault conditions by Over-temperature using the Push to Test function. Hold down the Reset button for 5 seconds to activate the fault Aux (97, 98) and shut down the SMC- The SMC-Delta monitors the SCR temperature by means of internal 3. thermistors. When the power poles maximum rated temperature is reached, the microcomputer switches off the SMC and a TEMP fault is indicated via LED. LED Description (Number of Flashes) 1.

This protects from motor burnout during single-phase 4. Phase Loss/Open Load starting. 5. Phase Imbalance 6. Shorted SCR 7. Test Phase Imbalance The unit monitors for imbalance between phase currents. To prevent motor damage, the unit will trip if the phase imbalance exceeds specified limits and a fault will be indicated on the LED. 26 Visit our website: www.ab.com/catalogs Bulletin 150 Smart Motor Controllers - SMC-Delta™ Cat.
