Variable Frequency Drives

More About Variable Frequency Drives

With 106 different Controls Variable Frequency Drives at your disposal, choose the version that suits your heating and cooling needs.

The Controls’ Variable Frequency Drives (VFD) manage the HVAC systems. It has an adjustable speed drive to help power different speeds and torque in an AC motor.

Manufacturer LSIS offers both the C100 and S100 models. Additionally, each the manufacturer updated both models over the past few years to provide you with a small device that optimizes the design for thermal analysis. The C100 is 33% smaller than other models, while the S100 is 60% smaller than other models.

The S100 is still larger than the C100 models. The C100 is built to fit into smaller control cabinets and works as a potentiometer.  Because of the size, some C100 models do not have a keypad.

In addition to the standard AC power, all devices have a built-in DC reactor that improves the power factor and decreases the Total Harmonic Distortion (THD). The LSIS devices also meet with global compliance standards set by both United Laboratories (UL) and Conformité Européene (CE).

LSIS recommends you change the default settings on both the C100 and S100 devices to protect the motor, drive, and application. While they do work on the standard settings for some applications, you need to check the app and settings before using them.

Variable Frequency Drive (VFD) horsepower ranges from 1-75kW

VFD comes in three phases

• Single phase 200-240 VAC
• Three Phase 200-240 VAC
• Three Phase 380-480 VAC

Different IP66/MEMA4x casings protect the device from different levels of water.
