VEC Energy Management System

* Single Channel VEC

** Dual Channel VEC

*** Multi Channel VEC


VEC-A-60A  and VEC-A-60A-2C are designed to allow the connection of electrical loads such as EV chargers, hot tubs, and other loads, to a panel that is at full capacity without requiring an upgrade.  VEC provides an opportunity to avoid costly upgrades in existing homes and facilities


VEC Operation

  • The current of lines L1 and L2 is read by two split core current transformers
  • If the real-time power consumption of the panel exceeds 80% of the main circuit breaker capacity, the VEC’s controller (referred to as the ‘VEC’) will, after a short adjustable time delay, de-energize the connected load to the power relay. This is a safety measure to prevent damage to the main electrical panel and ensure that the circuit is not overloaded.
  • The VEC will re-energize the power relay when the power consumption of the main electrical panel falls below 80% of its capacity, taking into account the size of the load and the total power consumption. The re-energizing process will occur after an adjustable time delay.
  • The VEC connects the power relay at a given current and time based on the user’s settings and application.
  • The output of the power relay can be connected to loads such as EV chargers and so on.


  • User can communicate with the VEC through Wi-Fi and change the settings.
  • The wireless connection allows the user to adjust settings and monitor the L1 and L2 currents and timings in real-time.
  • User can change the device’s name and password to enhance security and select a custom device name.
  • An excellent device for Load Management and Load Shedding purposes with Diverse Applications.
  • Upon request, the other model of the VEC can handle load shedding for any range of current or voltage.
  • Advanced Multi-Load Control Capabilities.
  • NEMA – 3R enclosure is available for outdoor installations.
  • Using split core current transformers for ease of installation and connection.
  • CSA SPE-1000-21 Approval

Dual Channels

The Dual-Channel VEC operates on a priority-based system for managing loads. It categorizes each load with a priority level, determining which load takes precedence when there’s limited power available.

Dual Channel VEC operates according to the following sequence:

  • Priority Assignment: Each load connected to Dual-Channel VEC is assigned a priority level. For instance, Load 1 might be designated as a higher priority than Load 2.
  • Power Monitoring: Dual-Channel VEC continuously monitors the available power supply from the source, such as an electrical panel.
  • Load Activation: When sufficient power is available, Dual-Channel VEC activates the load with the highest priority. This load starts drawing power from the source.
  • Time Delay: Dual-Channel VEC includes an adjustable time delay before considering the activation of the next load. This delay allows the system to stabilize after the first load is connected.
  • Second Load Activation: Following any specified delay, if conditions permit the activation of the second load according to priority, it is initiated, and both loads remain connected.
  • Power Shortage Scenario: In the event that there isn’t enough power to sustain both loads, Dual-Channel VEC initiates a load-shedding process.
  • Load Deactivation (Shedding): The load with the lower priority is deactivated first, ceasing its power draw.
  • Power Assessment: Dual-Channel VEC then evaluates if the available power is sufficient to maintain the remaining load. If so, the system continues to operate with the higher priority load.
  • Shutdown of Higher Priority Load if Insufficient Power: In cases where even the power supply is inadequate to sustain the higher priority load, VEC will initiate a shutdown of the higher priority load.
  • Re-evaluation: Depending on Dual-Channel VEC ‘s configuration, it constantly re-evaluates power availability and attempts to re-activate the loads, based on priority and adjustable delays, if conditions improve.

This process continues as long as there’s a power shortage. Dual-Channel VEC ensures that critical loads receive priority power, guaranteeing essential services even in situations of limited power supply.
