Inverter Ratings
NORDAC SK 300E
Motor Mounted Frequency Inverter
For select HP ratings, NORD can provide a fully programmable,
high performance AC vector frequency inverter mounted on the
motor. This motor mounted inverter:
• Eliminates the need to separately mount & wire the inverter
• Insures inverter/motor compatibility
• Has an IP 55 washdown duty enclosure
• Provides Electronic Motor Overload protection
• Insures smooth constant torque operation down to
2 Hz (check motor thermal limitations)
• Features a unique plug-in construction where the
program stays with the motor, minimizing return to
service time in the event of inverter replacement
SK 300E Inverter Ratings
• 200-240 VAC 3 phase 50/60 Hz input, ½ through 3 HP
• 380-480 VAC 3 phase 50/60 Hz input, 3/4 through 5 HP
• Full range of built-in pre-engineered options available
Selection Steps
1) Choose the SK300E-trio inverter based on motor ratings and input line voltage
2) Select the required Trio Interface (TI)
3) Select the braking resistor if required
4) Select additional customer based I/O if required (SK CU2-STD)
5) Select cover mounted technology unit if required
6) If remote wall mounting is required
7) Select any needed programming tools
