Compact inverter focuses on affordability and performance
22 April 2025 
Omron has launched a compact, cost-effective inverter for low-end applications where space, reliability and price are decisive factors. The J1 inverter provides essential motor control capabilities with a focus on affordability and performance. It is particularly suitable for applications such as conveyors, mixers, small fans, pumps and basic material-handling systems, in sectors such as food & beverage, general manufacturing, agriculture and HVAC.
Despite its compact size and accessible price point, Omron says that the J1 delivers functions typically expected in higher-tier models. It controls single-phase 220V motors from 0.4–2.2kW, and three-phase 400V motors from 0.4–3.7kW. It incorporates V/f control, dynamic torque vector control, PID control and overload protection. It also supports automatic deceleration, a sleep mode for pump and fan applications, and slip compensation to ensure stable torque, even at low speeds.
The inverter has a maximum output frequency of 400Hz, and an overload capability of 150% of the rated output current for one minute.
A compact IP20 housing allows side-by-side mounting to save cabinet space. Communications are handled by Modbus RS-485, and the J1 includes both digital and analogue I/O options (0-10V DC and 0-20mA) to suit basic machine control requirements.
To support both new and existing customers, the J1 can be programmed using Omron’s existing Sysmac Studio software, or a newly developed, free-of-charge configuration tool called J1 Editor, which offers quick parameter editing and simplifies set-ups.
The J1 is certified for CE, UKCA, UL/cUL, EAC and RoHS compliance.
