Product Description:

The 175H1011 adjustable frequency drive delivered by Danfoss has live electrical parts for a brief duration even after the AC line is connected. This drive may start as soon as AC power is applied. The product’s electrical installation is allowed only by skilled personnel. This device is subject to failure because of improper installation. The unit operates with a motor. Its maximum permitted installation altitude is 2000 m. This drive’s user must ensure proper grounding for incoming power according to the National Electrical Code.

The product features compliance with EMC 89/336/EEC directives if the installation specifications in its manual are followed and shielded cables are used. This device has wiring access knockouts at the bottom of its NEMA 1 enclosure. The unit is an AC drive with VLT branding. It has a voltage rating of 380 VAC to 415 VAC. This drive comes integrated with a rectifier that converts the incoming AC power to the required DC power. The product is positioned between the motor and the power supply. This device can also adjust the voltage and frequency to the motor according to the current processor demands. The unit features low energy consumption. It portrays compatibility with AC induction motors.

This adjustable frequency drive must be cooled before service or maintenance. The product is deployed in HVAC systems to control the speed of their fans. This device’s inverter helps in the conversion of the DC voltage from the DC circuit into an AC voltage with a variable frequency and voltage. This unit is prone to overheating if the access area is not sealed properly. It is mounted vertically on a flat surface.
