Ultra-Mini Microstepping Driver

Exceptionally small, easy to interface and powerful enough to handle the most demanding applications, the IM483H and IM805H measure a mere 2.6 in. x 2.1 in. x .36 in. These high-performance, low-cost microstepping drivers utilize advanced hybrid technology to greatly reduce size without sacrificing features. Both drivers share a common package and pin configuration, giving the system designer considerable flexibility. With only a single interface, the design provides for a wide power range, The IM483H accepts input voltage from 12 to 48 volts and has maximum output current of 3A RMS and 4A peak. Substituting the IM805H provides for input voltage from 24 to 75 volts and maximum output current of 5A RMS and 7A peak.

Available as an option for the drivers is the HFC-22 Heatsink/Fan/Clip assembly. This unique cooling solution was designed specifically for the drivers. It will easily maintain a reliable rear plate temperature without the need to use large heatsinks and cumbersome mounting hardware. The heatsink and fan are easily mounted to the driver by means of a patented removable clip developed by the company. The HFC-22 fully assembled with the IM483H or IM805H takes up only 6.8 inches of space.

The two drivers have 14 built in microstep resolutions (both binary and decimal) that can be changed at any time without the need to reset the driver. This feature allows the user to rapidly move long distances, yet precisely position the motor at the end of travel without the expense of high-performance controllers. In many instances, mechanical gearing can be replaced with microstepping. This reduces cost and system size, and eliminates potential maintenance while increasing accuracy and smoothness. With the development of proprietary and patented circuits, ripple current has been minimized to reduce the motor heating that is common with other designs. This feature allows the use of low inductance motors to improve high-speed performance and system efficiency.

The IM483H/IM805H microstepping hybrids are designed to be soldered or socketed directly into a PC board. This eliminates the need for wiring and mounting, thus saving design and assembly time, reducing system cost and increasing reliability. The ultra-small size reduces the overall space required in a system. In addition, each unit is 100% tested and comes with a 2-year warranty.
