Specifications Parameter Category Details Manufacturer & Series Schneider Electric, Altivar 212 Complete Model Number ATV212HU75N4 Product Type Variable Frequency Drive for Pumps & Fans Rated Output Power 7.5 kW Rated Output Current 17.5 A Motor Power (HP) 10 HP Supply Voltage 3-phase, 380 - 480 V AC (±10%), 50/60 Hz Output Voltage 3-phase, 0 to supply voltage, 0.5 to 500 Hz Control Method Scalar (V/f) control with dedicated pump & fan curves. Key Features for Pumps & Fans • Dedicated Application Macros: (1 pump/1 fan, 2 pumps/2 fans with alternation, 4 pumps/4 fans with cascade control). • Energy Saving Mode (AVC): Automatically reduces motor magnetizing voltage at partial load. • Sleep/Wake Function: Stops the drive under low demand and restarts automatically. • Pump/Fan Cleanout Function: Periodic reverse operation. • PID Regulator: For closed-loop control of pressure, flow, or level. • Built-in PLC Functionality. Standard I/O • Digital Inputs: 4 (configurable) • Digital Outputs: 2 (1 relay, 1 transistor) • Analog Inputs: 2 (1 voltage 0-10V, 1 configurable voltage/current 0-10V/0-20mA) • Analog Output: 1 (0-20mA) Integrated Communication Ethernet (Modbus TCP/IP) port as standard (indicated by N4). Communication Slots 1 slot for optional communication cards (e.g., PROFIBUS DP, DeviceNet, BACnet MS/TP, other Ethernet protocols) or I/O expansion cards. Keypad / Display Not supplied standard with "N4" versions. Requires separate purchase of a compatible keypad (e.g., graphical display keypad). Enclosure IP20 / UL Type 1 (Panel-mounted, requires installation in a suitable enclosure). Protection Features Motor overload, short-circuit, ground fault, overvoltage, undervoltage, phase loss, overheating, pump dry-running detection (based on power monitoring). Braking Standard DC injection braking. Suitable for fan and pump deceleration. For faster stopping, an optional dynamic braking resistor is required. Ambient Temperature -10°C to +50°C (with derating above 40°C). Up to +60°C with significant derating. Storage Temperature -25°C to +70°C Relative Humidity 5% to 95% (non-condensing) Pollution Degree 2 Standards & Certifications CE, cULus, RoHS, compliant with IEC 61800-5-1, IEC 61800-3. Configuration Software SoMove (Free software for commissioning, parameter management, and monitoring). Typical Applications HVAC systems (cooling tower fans, chilled water pumps, air handling unit fans), water supply and boosting systems, wastewater treatment (aeration blowers, transfer pumps), industrial ventilation.
