Elmo’s family of analogue servo drives, The Dragonfly, Butterfly, Robin, Condor, Canary, and Raven are unique in they are low voltage DC input and built to military standards for extreme environmental conditions including but not limited to, vibration, temperature and altitude.

They are current mode pulse width modulated servo amplifiers for brush and brushless motors. The ExtrIQ analogue amplifiers are highly durable and capable of operating under extreme environmental conditions.

Each amplifier series exhibits excellent servo performance, efficiency, high quality and reliability – all in sleek and compact, high-density power packages. Outstanding motion control is achieved through the implementation of Elmo’s proprietary switching and control methods enabled by fully customised dedicated ICs and advanced heat transfer and dissipation. Elmo also has a range of digital servo drives to the same extreme environment.
