Basic SL and SLX-series Three Phase DC Drives

Basic system drives for OEMs – not including fuses, contactor, etc.

SLX50Model SLX50/122, up to 75hp

(Size 1)

These drives are available as both single direction 2-quadrant (SL) and a full 4-quadrant, regenerative (SLX) drives in different builds up to 75hp. Like the other system drives available from Bardac, they are modern, sophisticated, high performance products designed for world wide markets.

A drive.web online system builder option (available May 2004) uses
Ethernet to enable these drives to be integrated into cost effective systems
of any size or complexity. The drive.web option can be easily added
retrospectively to any installation to provide improved functionality,
connectivity, diagnostics and Internet access.

These compact, high performance drives provide flexibility to OEMs who may need to use different power components to meet special user requirements. (Fuses, contactor, etc., would have to be fitted externally)

We also offer a completely digital DC drive in our PL/PLX Series.
