Power Switching Units>> Static Power Switching Unit
The Series SPX range of Static Power Switching Units are designed using state of the art techniques in power switching, thus providing instantaneous and bump-less transfer of power to the output load. Offered in several power ratings, these Static AC Power Switching Units are available in sleek and attractive 1U Rack-mount enclosures in compact and rugged execution and low weight.

These Power Switching units incorporate the latest micro-controller sensing combined with current mode PWM controllers, UFR diodes, MOSFETs and ferrite–core transformers for providing efficient power control and reliable field performance. The Series SPX SMPS units are designed for continuous full load operation in tough industrial environments, while ensuring the protection of the powered equipment by providing galvanic isolation between input and output, besides complete RFI and EMI filtering.

Additional features such as a Digital indication of Voltage, Current and Switching Time, combined with an active mimic indicating the status of the power switching are also provided for ease of operation.

All ASHE instruments carry a lifetime warranty against defects in components and workmanship.
