Product Description:

The 136U2803 is an AC drive produced by Danfoss for the VLT FC 302 Automation Drives series. It is designed to regulate induction-motor speed in conveyors, pumps, and general machinery, providing closed-loop torque control where accurate acceleration and deceleration are required during routine machine operation. This supports variable-speed control in automated equipment and helps the connected motor follow changing process demands more precisely than fixed-speed operation. It is suited to applications that need repeatable starts, stops, and speed changes across normal duty cycles.

The drive accepts three-phase power through its mains terminals and operates on a supply of 380 - 500 VAC. With a continuous output capability of 15 kW, which is mechanically equivalent to 20 HP, it supports medium-sized motors used in conveyors, pumps, and other automated production equipment. Regenerated energy during rapid deceleration is dissipated by an integrated brake chopper. The A-slot is factory-populated with a PROFINET MCA 120 card for real-time industrial Ethernet communication, and the B-slot contains the MCB 103 resolver interface for position feedback. The remaining option slots are left empty, which keeps the internal layout straightforward for standard cabinet wiring.

User interaction is handled by the front-mounted Numerical Local Control Panel, which provides direct access to operating parameters, status information, and local setup functions. The enclosure has an IP20 / chassis rating, and a factory-installed RFI filter helps reduce conducted emissions on the supply side. The control boards have a coated finish that improves resistance to moisture and airborne contaminants in typical plant atmospheres. Standard cable entries support routine wiring, and the installed options focus on core drive control, network communication, and resolver feedback without extra slot hardware.
