Saci E-Joy MM9 variable frequency drive for pool pumps

Saci [e]Joy MM9 Variable Frequency Drive – Ref. 801D1020

The Saci [e]Joy MM9 variable frequency drive is designed to control any 220–240 V single-phase pump of up to 1.1 kW (1.5 HP), providing energy savings of up to 70% through motor speed regulation. The unit is extremely easy to configure and is suitable for both new pools and existing installations.

It features a multilingual backlit display and allows up to 4 daily cycles to be programmed, with 3 user-adjustable speeds within the range of 700–2800 rpm. It also includes integrated protection against overvoltage, excessive electrical consumption, and dry running, ensuring pump safety and extending its service life.

The [e]Joy MM9 variable frequency drive also includes highly useful additional functions, such as a filter-cleaning assistant, two digital inputs for external control, and two independent relays capable of monitoring the pump status, activating a salt chlorinator, or managing pool light switching.

Optionally, an expansion card can be used to add Modbus connectivity, two additional digital inputs, and external control via a 0–10 V signal, making the MM9 an extremely flexible solution for advanced automation of filtration equipment.

The variable frequency drive is especially recommended for Saci pumps such as Optima and single-phase Winner, although it is compatible with any equivalent single-phase pump on the market.
