30 hp, vfd, variable frequency ac motor speed drive


380 ~ 480VAC Three Phase Input.
If you have 200 ~ 240VAC Input:
HITACHI L300P Series is a Variable Torque Drive
V/F optionally variable, constant torque, and reduced torque of V/F control.
120%, 30 Seconds 150%, 0.5 Seconds
0.1 - 3600 sec. (linear/curve, accel./decel.), Two stage accel./decel. setting available
Built-in BRD circuit (Optional resistor) for 15, 20 HP only. External dynamic braking unit (option) for 25 HP & above. Braking resistor is not integrated in the inverter. Please install optional braking resistor or dynamic braking unit when large control torque is required.
Performs at start; under set frequency at deceleration, or via an external input (braking force, time and operating frequency)
Up(1) and Down(2) keys/value setting keys.
