Product Description:
The 134H5277 is an AC variable-frequency drive manufactured by Danfoss for the VLT 2800 Low Voltage Drives series. It regulates the speed of induction motors used in process automation by varying the frequency and voltage supplied to the motor. This capability allows pump and fan output to follow real-time process demand without depending on mechanical throttling. The drive is intended for installation in a control panel and can support speed-controlled equipment in processing plants, material-handling systems, and other industrial applications.
The drive accepts a mains input of 380–480 V ±10% at 50/60 Hz from a three-phase supply. It converts this input into a modulated output for motors with up to 0.55 kW of continuous power, which corresponds to 0.75 HP. The enclosure has an IP20 rating, providing protection against accidental contact with internal electrical parts when the unit is installed inside a suitable cabinet. A conformal coating protects the internal circuit boards from airborne contaminants that could otherwise affect electrical performance. The built-in SLCP display presents operating values and drive parameters locally, allowing settings and status information to be viewed without an external keypad. Its electrical capacity is suited to small centrifugal loads and other low-power machines operating from common industrial supply voltages.
Electromagnetic emissions are controlled by an integrated EN 55011 A1 (IT mains) RFI filter, which supports operation on isolated transformer systems and helps limit conducted interference. The narrow book-style housing uses shared cooling channels, allowing multiple drives to be installed side by side while preserving airflow through the panel. Local controls provide access to operating information and basic parameter adjustments at the drive. The unit is supplied in a standard configuration with a brake, allowing braking energy from rapid deceleration of light-inertia loads to be managed by the drive system. No application option is installed, and the fieldbus slot is unused. Control commands can therefore be handled through the available panel controls and standard drive interfaces for general process applications.
