Product Description:
The 134L9259 is an AC variable frequency drive produced by Danfoss for the VLT FC 202 AQUA Drives series. The unit converts fixed-frequency three-phase mains power into a regulated output that allows precise speed control of centrifugal pumps in municipal or industrial water-handling systems. Within an automation cabinet, it occupies the A2 frame envelope and modulates motor torque to match hydraulic demand, lowering energy consumption and reducing mechanical stress on connected equipment.
The drive delivers a rated shaft power of 0.25 kW, drawing a nominal input current of 1.6 A while providing a continuous output current of 1.8 A to the motor terminals. Under full load, the apparent power presented to the supply is 0.65 kVA, so line components must be sized for that capacity. For overcurrent protection, Danfoss specifies a maximum prefuse of 10 A, which coordinates with branch circuit breakers and limits fault energy. These electrical values support appropriate cable selection and thermal management for the connected motor circuit.
The plastic housing has an enclosure rating of IP20, making the drive suitable for installation inside a protective electrical cabinet. Networked control is supported through the PROFINET MCA 120 option card, enabling real-time setpoint updates and diagnostic communication over Ethernet. Conducted emissions are attenuated by an internal filter rated Class A1/B, helping installations meet applicable residential and light-industrial electromagnetic compatibility limits. The graphical local control panel provides access to operating parameters, while three PT100 or PT1000 sensor inputs allow direct process temperature feedback. Continuous operation is permitted at ambient temperatures up to 50 °C; operation above this threshold requires derating. The drive measures 268 × 90 × 205 mm (H × W × D) and produces 21 W of internal power loss, both of which should be considered when arranging cabinet space and airflow. Adequate clearance around the housing allows heat to leave the unit without obstructing nearby control components.
