is a higher-capacity variable speed drive (VSD) in the same series, rated for 110 kW (150 hp) for normal duty applications. It is a larger unit than the previous models you inquired about, moving up to a larger frame size.
These specifications are essential for ensuring enough cabinet space for this heavy-duty unit:
Weight: 188.50 lbs (85.5 kg)
Height: 33.46 in (850 mm)
Width: 11.81 in (300 mm)
Length (Depth): 14.76 in (375 mm)
Core Functions & Features
Dual-Rating Performance: Supports 110 kW (150 hp) for normal duty (up to 120% overload) and 90 kW (125 hp) for heavy duty (up to 150% overload).
Application Focus: Engineered specifically for pump, fan, and compressor applications in segments like water/wastewater and oil & gas.
Robustness: Features electronic cards with protective coatings and busbar plating to resist corrosion from chemical gases.
Communications: Includes built-in Modbus serial and supports optional Profibus DP V1 cards for integration into industrial networks.
The Schneider Electric ATV610C11N4 provides the same intelligent control functions as the smaller units in the Easy Altivar 610 range, but it is scaled for high-power 110 kW (150 hp) industrial systems.
Core Operational Functions
High-Power Speed Control: Converts 380460V AC power into variable frequency to precisely manage the speed of massive 110 kW motors.
Torque Optimization: Specifically tuned for Variable Torque applications (like centrifugal pumps and fans) to maximize efficiency and reduce mechanical wear.
Dual Rating: Can be configured for Normal Duty (110 kW) or Heavy Duty (90 kW), allowing it to handle higher starting loads if required.
Advanced Pump & Fan Functions
Multi-Pump Link: Allows the drive to control several pumps in a "Lead/Lag" configuration to maintain constant pressure in a water network.
Pipe Fill Function: Prevents "water hammer" damage by slowly filling empty pipes before ramping up to full pressure.
Catch-on-the-Fly: Safely picks up and controls a motor that is already spinning (e.g., a fan being turned by natural wind/draft) without tripping.
Dry Run & Anti-Jam: Protects pumps by detecting if they are running without fluid or if the impeller is clogged with debris.
Protection & Safety
Integrated DC Choke: Vital at this power level (110 kW) to suppress harmonic distortion and protect other sensitive electronics on the same grid.
Corrosion Resistance: All internal circuit boards feature 3C3 conformal coating, making it functional in high-moisture or chemically aggressive environments like wastewater plants.
Thermal Safeguards: Monitors the temperature of both the motor and the drives internal power modules to prevent overheating under heavy loads.
Communication & Integration
Modbus Serial: Comes standard for linking the drive to a PLC or SCADA system.
Energy Monitoring: Provides real-time data on energy consumption, helping facilities track and reduce their carbon footprint.
