MODEL 1355 DESCRIPTION The Curtis Model 1355 is a compact and affordable solid-state alternative to electro-mechanical contactor panels. It offers fully programmable soft-start and current-limiting control of up to 5 brushed DC permanent magnet or series wound motors, via CANbus commands or direct digital inputs. APPLICATION Typical applications include Sweeper-Scrubber floor care machines, or any other 24-36VDC application requiring control of multiple loads up to 100A each. FEATURES • Microprocessor based design substantially reduces installation labor and physical space requirements. • Five drivers, Ml - M5, for motor loads, rated for 100A peak current. • Ml - M5 motor drivers offer soft start and current limiting capability. • Optional three, 10A full bridge actuator drivers, controlled via CANopen control commands. • One 3A driver output, for a main (line) contactor. • Optional six digital inputs allow stand-alone control of five motor loads. • H-bridge mode allows bidirectional operation of a single motor load. • Ability to connect outputs in parallel to drive a single larger motor load. • Ability to connect multiple 1355s throughout a vehicle control system. • Accurate motor, actuator current measurements and full diagnostics reported via CANbus. • CANopen interface allows interconnection to a wide range of products, including the Curtis line of AC motor speed controllers and Curtis vehicle system controllers. • Heavy duty threaded M6 bus bars for battery and M5 for motor connectors eliminate reliability issues often found with push-on power connectors. • All logic connections via reliable, IP65 sealed 14-pin AmpSeal connector. • Robust IP65 sealed enclosure provides excellent chemical resistance and protection from harsh environments. • Designed to withstand high levels of bump, shock and vibration. • Programmable 24 or 36VDC nominal supply. • Externally viewable power/status LEDs. • Serial communication port for Curtis 1314/1313 programming tools.
