AR100 VSD Pump Controller, 37 kW, 380 V Three-Phase

Description

Overview

The AR100 37 kW 380 V VSD pump controller is a variable speed drive that holds water pressure constant by adjusting pump speed to match demand. It is rated for 37 kW motors on a 380 V, 3-phase, 50 Hz supply, so it suits pumps of that size and voltage class. At 380 V it suits standard three-phase motors on most farm, commercial and municipal supplies.

At 37 kW it drives mid-size borehole, booster and irrigation pumps. Soft start and stop, dry-run and overload protection and multi-pump control come as standard functions, and the digital LED display shows run and stop status.

Key features

• Constant pressure control holds the set pressure as demand changes.
• Soft start and soft stop ease the load on the pump, motor and pipework.
• Multi-pump alternation and cascade control for booster sets with more than one pump.
• Dry-run protection and overload protection guard the pump.
• Digital LED display with run/stop and pump status indicators.
• Variable speed operation cuts electricity use compared with running at full speed.
• Rated 37 kW at 380 V, 3-phase, 50 Hz.

Where it works

The AR100 is used on borehole pump systems, commercial and industrial water booster sets, irrigation pump stations and multi-pump fire and process water systems, anywhere stable pressure and lower energy costs matter. Irrigation pump stations in the Free State and KwaZulu-Natal can run one or several pumps from a single pressure setpoint. Before ordering, confirm that the 37 kW rating and 380 V supply match your pump motor plate. Not sure? Contact us with the motor details and we will confirm the right AR100 rating for your pump.
