What is a VFD Control Panel?

Variable Frequency Drive or VFD are control panels that help control the speed of electric motors and feed pumps used in various industrial facilities. Each motor has a different frequency and voltage and hence, a separate VFD control panel is required to monitor and control them. 

With VFD panels, you can bring multiple motors with variable frequencies and voltages under one roof. This will also protect your motors from moisture, corrosion, dust, and other damaging elements. 

VFDs are a crucial part of any manufacturing plant. Without them, the plants will not be able to maintain their output consistently. It can also cause failures that can severely hamper the production capacity of the plant. 

Like other control panels, VFDs comprise a range of equipment such as:

  • Harmonic filters
  • Protective equipment such as relays, circuit breakers, and stabilizers
  • A bypass control to keep the VFD operational in all conditions
  • Programmable Logic Controllers (PLC) for advanced control
  • Communication equipment such as switches and modems
  • Temperature control equipment such as air conditioner or anti-condensation heater
  • Motor starters

Benefits of a Variable Frequency Drive (VFD)

Does your industrial facility need VFD? Absolutely! Here are the top 4 reasons why you should get a VFD for your manufacturing unit: 

  • Power switching and protection – VFD control panels act as an intermediary between the power source and your equipment. In case there is a short circuit or a power overload, it will cause the circuit breaker of the VFD to trip. This way, your drive or any equipment connected to the line will not get affected. 
  • Speed backup – The VFD panel doors usually have a frequency control potentiometer. This helps send command signals to the motor as per the operator’s settings. In case the VFD fails, a bypass switch helps keep the motors functioning.
  • Equipment protection – Any manufacturing plant workplace is filled with moisture, dust, and other damaging particles. It can be cumbersome to protect your equipment from these. Long-term exposure to these materials can damage the tools permanently. One of the major risks is chemical accumulation on the open connections that can negatively impact performance. Moreover, dirt accumulation can reduce the lifespan of the equipment too. 
  • Visual control – VFD panels can provide crucial real-time data on the drive’s energy consumption, frequency, and other diagnostic data that operators require. Operators can also use the embedded controls to shift frequencies or take precautionary measures as per the monitored values. 

NEMA Ratings

VFD control panels have different ratings from the National Electrical Manufacturers Association (NEMA). There are 13 ratings, some of which are: 

  • Type 1: General purpose, for indoor use, protection against solid foreign objects
  • Type 2: Similar to Type 1 but with extra drip shields
  • Type 3: Protecting the equipment from external weather conditions such as rain
  • Type 3R: For outdoor use
  • Type 4: Water-tight, shielding equipment from at least 65 GMP of water

You can choose a specific protection by VFD panels based on the NEMA guidelines for the best usability and equipment protection. 

How can VFDs reduce energy consumption?

VFDs can reduce energy consumption significantly and help save production costs. Traditionally, motors would need valves and dampers to control pumps and fans. This would consume huge amounts of energy. VFDs can do the same without consuming so much energy. Moreover, the flexibility to adjust fan and pump speeds offers more control to operators to save energy.

Diesel Engine Control Panel

Control panels provide a simple user interface to operate, monitor, and control an otherwise complex piece of machinery. Their foremost and most basic feature is the switches to start or stop the machine. Visually these panels indicate the measurements of various parameters of the machine such as voltage, current, and frequency. In case the machine overheats, over speeds, or slows down due to a number of internal and external factors, control panels also facilitate an intervention. In this blog, we unpack the features, uses, and capabilities of a diesel engine control panel for you.

The most important function of diesel engine control panels is to control and protect the diesel engine. The control panel comprises a set of integrated components that monitor the diesel engine parameter readings to stay within the safe levels. The diesel engine control panel functions through the coordinated action of the following components:

  1. The Diesel Controller Unit 

Just like the CPU of a computer, the control module is the brain of your panel. It is a device that controllers the circuit of the panel using a microprocessor controller and paraments of a diesel engine based on changing conditions or shifts in parameters.

  1. The Terminal Rail

This is the junction of all the wires and connectors coming from the engine and the alternator. These wires are linked to the control panel to establish a two-way connection between the engine and the panel. Inputs on the control panel reach the engine and alternator while changing parameters in the engine and alternator are relayed to the panel.

  1. Battery Charger 

Inside the control panel, there are independent fully automatic microprocessor-controlled battery chargers rated at 10 Amps. The battery chargers operate in such a manner as to ensure that the engine batteries are fully charged within 24 hours. PCB mounted LEDs are provided for indication of AC Power On, and Battery Power On.

  1. Circuit Breaker

Just as in many other electrical and electronic devices, the role of the circuit breaker is to stop the flow of current in case of overload or short-circuit. This mechanism is very crucial to keep your diesel engine safe from a sudden spurt in electricity.

The diesel engine control panel is thus an effective device to monitor and control your generator. These days, the panels also include hi-tech LCD screens, displays showing running time, oil pressure and temperature sensors, remote start or stop capabilities, and an emergency shut-down lever. While most manufacturers include these as standard features, you may place an order to assemble a customized control panel based on your unique requirements.
