DIGITAL AC CRANE DRIVE – 2.2 KW
AC Drive should be suitable for Heavy duty operation of 2.2 KW. Offered AC drive should be suitable for Crane-Hoist operation. If
separate software required for crane application
it must be clubbed with supply of material. AC Input Voltage: 380 to 480V AC 10%
3 phase
3 wire
50 Hz; Mode of control: Bi-directional fully controlled 3-phase AC; Speed regulation: 1% of base speed; Braking: Suitable Dynamic Braking Resistance and Chopper unit (External or in-built); Acceleration time: 0.1 to 1000s or better; Deacceleration time: 0.1 to 1000s or better; Overload: 150%-1min
200%-3.0s; Ambient temperature: 0 to 50°C (Derating shall not occur below 50°C. In the event that derating occurs below 50°C
the supplier shall provide a higher-rated drive to match the requirement); Rated Current at 50°C: Min. Current should be 5.5 Amps at 50°C; High starting torque at low speed: 200% starting torque at 0.3 Hz; Two analog inputs: Two nos. analog inputs having signal voltages of 0 to 10 VDC or 4 to 20 mA (configurable); Two analog outputs: Two nos. analog outputs having signal voltages of 0 to +/-10 VDC or 4 to 20 mA (configurable); Six digital inputs: PNP/NPN; One relay output: With short-circuit and overload protection; Two Digital Outputs: With short- circuit and overload protection; Brake release signals: Outputs braking signals based on inverter operating conditions to prevent cargo bed rollback and overrunning; Load adaptive control: When the actual load level is lower than the configured load level
the system can be operated at a ratio-multiplied speed (in terms of the configured frequency)
resulting in significantly better efficiency; Load
