Yaskawa GA500 Series AC Inverter for 4kW (5HP) 400V 3ph motor to 9.2A at high overload or 5.5kW (7.5HP) to 11.9A when Fan/Pump rated. Operates in VxF or Sensorless Vector and converts fixed frequency Three Phase 400V input to variable frequency Three Phase 400V to control a standard AC induction, permanent magnet or synchronous reluctance motor.
Size 3c: 140mm Wide x 193mm Deep x 128mm High. IP20.
Weight: 2.6kg.
Overload: 150% x 60 seconds. High Overload. (Once every 10 minutes)
Overload: 110% x 60 seconds. Fan/Pump Rated. (Once every 10 minutes)
Speed Control Range: 0-590Hz.
Braking (DBr): Built-in braking transistor for 100% Torque for 10 seconds every 100 seconds (10% duty cycle). A 100 Ohm minimum external resistor is required for Dynamic Braking. Resistor is not supplied and should only be fitted if this feature is required.
