Abstract
Systems and methods for limiting inrush current spikes in multi-load systems are disclosed. Inrush current limiting modules according to some embodiments comprise programmable microcontrollers and logic activated switches that connect loads to main power in a staggered and non-simultaneous manner thereby limiting inrush current spikes. Applications include agricultural grow systems employing multiple grow light fixtures and other high power and multiple load systems. Programmable logic controlled switching mechanisms operating under reserve power and integrated into power supplies are also disclosed.
Claims20
A method for limiting or attenuating inrush current spikes when simultaneously connecting multiple loads to a main electrical power source comprising the steps of:
- receiving an electrical power signal at a first controller associated with a first load wherein said first controller controls a switching means for connecting said electrical power signal to said first load;
- generating a first time delay;
- and
- after the first time delay, activating a switching means for connecting the electrical power signal to the first load thereby electrically energizing the first load.
A circuit element for connecting an electrical power signal to a load while limiting or attenuating inrush or current spikes to the load comprising:
- a power conditioner;
- electrical switching means for connecting an electrical power signal to a load;
- a microcontroller that, upon receiving an electrical power signal, generates a time delay interval, and at the end of the time delay interval controls the electrical switching means to connect the electrical power signal to the load thereby electrically energizing the load;
- and
- a reserve power means for providing electrical power to the microcontroller.
A DC power supply with integrated switching means operable to limit or attenuate inrush current spikes when connecting the power supply to main power comprising:
- an input means for receiving electrical power;
- a power conditioner;
- a logic controlled switching mechanism for delaying when main electrical power, received via said input means, is connected to the portion of the power supply downstream from said switching mechanism;
- and
- an output means for delivering conditioned power to a downstream electrical load.
