The drives are said to be capable of controlling electric motors rated up to 480 Amps with a power rating up to 250kW / 400HP. They replace the existing Size 8 which was only available for control cabinet mounting with IP20 protection.
 
The new range also adds DNV marine certification, in addition to a built-in EMC filter to meet Category C3 with a factory fit option to upgrade to a high-performance EMC filter that meets Category C2. They also come with high-definition TFT displays as standard.
 
The IP20 and IP55 / NEMA 12 both have an ambient operating temperature up to 50°C and conform to UL, cUL, EAC and RCM, in addition to DNV.
 
The Optidrive P2 is designed for applications such as mixers, extruders, conveyors, cranes and hoists. It can provide up to 200% torque from zero speed, ensuring reliable starting and accurate speed control under all load conditions. The Optidrive Eco is now commonplace in controlling fans, pumps and compressors and is widely used in HVAC-R and the water industry.
