Variable Load Controllers

We are the leading manufacturer and exporter of an extensive range of Variable Load Controllers. These products are mainly utilized for variably controlling the IAQ devices based on the signals received from the IAQ monitors. The offered range have auto and manual mode of operation and is capable of accepting both 0–10 VDC and 4 – 20 mA signals.

Specifications:

• Variable Load Controller is an important component of Air Quality Management System and is utilized for controlling the power being fed to the Ozone Generating Modules
• It gets signals from the Central Controller. These signals are for Switching ON/OFF and increasing or decreasing the output of the Ozone Generation. The Input is a variable D.C. voltage from the Central Controller
• Variable Load Controller is located in a Control Panel. This enclosure integrates inter-connection of all the major components like Sensors for VOC, CO₂ and Ozone, Ozone Generating Modules and the signals from the Central Controller.
• The output of VOC, CO₂ and Ozone Modules can also be displayed on this Control Panel through a 4.3" colored touch screen Display. Most of the adjustments, calibrations and check-ups can be carried out from this display only
• Variable Load Controller will be fully factory assembled. Field provided connections will be limited to power wiring only
• The Controller will be provided with terminal block to connect incoming power, variable outgoing power, and for interlocking to AHU motor or other air moving device
• The Controller will be provided with a 4.3" Touch Screen Display along with a rocker switch to choose Automatic or manual Mode of operation. In the Manual Bypass Mode, voltage output of the Controller will be 100% of Input voltage, regardless of the level of VOC
