Product Description:
The 134G7453 is an AC drive manufactured by Danfoss for the VLT FC 103 Refrigeration Drives series. Intended for compressors, condensers, and evaporator fans, the unit modulates motor speed to match the thermal load and reduce energy use in industrial refrigeration systems. By converting fixed mains power into variable-frequency output, the drive supplies precise torque that helps maintain suction pressure and temperature setpoints without the frequent cycling associated with contactor-based starters. This speed control also allows connected refrigeration equipment to respond gradually as operating demand changes throughout a production cycle.
The drive accepts an input range of 380 to 480 VAC, which is suitable for common industrial utility feeders. Its continuous mechanical output is rated at 20 HP, equivalent to a shaft capacity of 15 kW, allowing it to operate medium-sized screw or scroll compressors. The enclosure has an IP21 / Type 1 backplate rating, providing protection against finger contact and vertically falling water drops when the unit is installed in a suitable panel room. An integrated Class A1/B RFI filter limits conducted electromagnetic emissions that could interfere with nearby equipment. Standard cable entries provide access for line and motor wiring without requiring a specialized entry arrangement. The configuration does not include a brake chopper, so the connected motor slows through natural deceleration during a controlled stop.
The drive includes a graphical local control panel that provides access to operating data, parameter settings, and status information. Fieldbus connectivity is available through the AK-LonWorks MCA 107 option board installed in slot A, allowing the drive to exchange control and monitoring data with compatible refrigeration control networks. Motor terminals receive power from a three-phase output bridge, which regulates the voltage and frequency supplied to the connected motor. The control electronics have coated PCB protection that helps resist moisture commonly present around refrigeration equipment and in cold-room environments. This coating reduces direct exposure of sensitive circuit surfaces to condensation and airborne contaminants during normal operation.
