Technical Data 2

2.2 SCF Model Designation Code

The SCF model number gives a full description of the basic drive unit (see example below).

EXAMPLE: SF210Y (SCF Series, 208/240 Vac, 1 HP, single or three phase input)

SF 2 10 Y

Series:

SF = SCF Series Variable Speed AC Motor Drive

Input Voltage:

2 = 208/240 Vac (For 208, 230, and 240 Vac; 50 or 60 Hz)

4 = 400/480 Vac (For 380, 415, 440, 460 and 480 Vac; 50 or 60 Hz)

5 = 480/590 Vac (For 440, 460, 480, 575 and 600 Vac; 50 or 60 Hz)

Rating:

03 = ¼ HP (0.20 kW) 30 = 3 HP (2.2 kW) 200 = 20 HP (15 kW)

05 = ½ HP (0.37 kW) 50 = 5 HP (4.0 kW) 250 = 25 HP (18.5 kW)

10 = 1 HP (0.75 kW) 75 = 7½ HP (5.5 kW) 300 = 30 HP (22 kW)

15 = 1½ HP (1.1 kW) 100 = 10 HP (7.5 kW)

20 = 2 HP (1.5 kW) 150 = 15 HP (11 kW)

Input Phase:

Y = Single or three phase input.

No character indicates three phase input only

Mounting Style:

F = Through-hole mount with special heatsink

F1 = Through-hole mount without heatsink (customer supplies heatsink)

No character indicates panel or DIN rail mounting

Application Speciﬁc Options:

P = PI (setpoint control) software

V = High Frequency Output - up to 1000 Hz
