APEX6151: 120 VAC Operation: 25A slow blow (Littelfuse #326-025 or equivalent)
240 VAC Operation: 15A slow blow (Littelfuse #326-015 or equivalent)
APEX6152: 12A slow blow (Littelfuse #326-012 or equivalent)
APEX6154: 20A slow blow (Littelfuse #326-020 or equivalent)
Isolation Transformer............................................... Not required
*For operation from single phase power, derate system performance according to motor
size and total system performance.
**The actual input power and current is a function of the motor's operating point (speed and
torque) and the duty cycle. You can de-rate the fuses by scaling the above numbers by your
actual requirements. The numbers above reflect the servo motor and drive operating at
rated speed and rated torque at 100% duty.
