The Control Techniques Unidrive M400 Pumping Solutions are a cost effective and versatile variable speed control system for maintaining energy efficient, constant water pressure in single-phase (0.33 - 50 hp) or 3-phase (0.5 - 200 hp) applications. These single-pump and multi-pump (up to 3 max) configurations utilize the onboard controller on the Unidrive M400 variable frequency AC drive (VFD) for economical and easy to use control.

Based on the highly reliable Unidrive M400 AC drive, these solutions provide programming dedicated to simplex and multiplex pump operation. The AI-CTASP (Simplex Pump) and AI-CTAMP (Multiplex Pump) options include an AI-BACKUP-ADAPTOR with SD memory card pre-loaded with default pump parameters to make application setup easy.

Additionally, an optional HMI (human machine interface) is available that makes setup and diagnostics easy and provides additional features such as remote web access and email alerts.
