More About Variable Frequency Drives

The Controls’ Variable Frequency Drives (VFD) manage the HVAC systems. They have 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 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 and great for energy savings, 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 like 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 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.

Among other VFD manufacturers represented in this category, there are also Schneider Electric with products such as ATV320U75M3C or ATV12H075M2, Siemens (BT300-CABLE, BT300-CNTLUNIT-F), and Johnson Controls (VS3-040-4-N2D-0, VS3-075-D-N2B-Q).
