Vari Speed® 180 Series
- Designed for multi-control, master/follower speed control applications for standard permanent magnet or wound-field DC motors
- 120 or 240 VAC line input, selectable
- Rated for 1/8 to 5 HP
- Isolated input terminals permit one or more drives to track a single process signal
- Interlocking relay for loss of AC power or motor loads greater than current limit setting
- Jumper-selectable armature and tachometer feedback for ease of set up regardless of voltages, motors, or tachometers used
- Tachometer follower input may be used to follow a speed signal from an AC or DC tachometer
- Available in chassis or NEMA 12
- Circuit breaker on NEMA enclosure models
- UR/cUR recognized chassis models
