Purchase now: Schneider Electric ATV630D37N4 Variable Speed Drive
Purchase now: Atlantech Drives provides you the Schneider Electric ATV630D37N4, a flagship **Variable Frequency Drive (VFD)** from the **Altivar Process ATV600** family. This drive is not just a motor starter; it is a «Service Oriented» device designed specifically for **Fluid Management** (Pumps and Fans) in industrial utilities. It handles a power rating of **37 kW** (Normal Duty) at 380-480V, making it the standard workhorse for medium-sized centrifugal pumps and ventilation fans.
Technical Specifications and Embedded Intelligence
The ATV630D37N4 comes IP21 rated for wall mounting. It distinguishes itself with **Embedded Power Measurement** (accuracy < 5%), allowing for real-time energy monitoring without external meters. It features dual **Ethernet Modbus TCP** ports as standard, enabling seamless integration into plant networks and providing a built-in **Webserver** for configuration and diagnostics via any web browser. The "Process" functions include specific pump curves, dry run protection, and anti-jam sequences.

Expert Tips: Using the «Pump Curve»
Stop guessing your flow. Expert Tip: The ATV630 allows you to upload the manufacturer’s pump curve data (Head vs Flow) directly into the drive parameters. The drive can then estimate the actual flow rate and operate at the Best Efficiency Point (BEP), saving huge amounts of energy compared to standard throttling valves. It can also detect if the pump is wearing out (lower flow for same speed) and alert maintenance.
Frequently Asked Questions (FAQs)
Q: What is the difference between ATV630 and ATV930?
A: ATV630 is optimized for variable torque (Pumps/Fans) and Energy efficiency. ATV930 is for constant torque (Conveyors/Crushers) and highly dynamic applications with braking resistors.
Q: Can I mount it side-by-side?
A: Yes, the «Book» format allows zero-clearance side-by-side mounting to save cabinet space, provided the top/bottom airflow is respected.
