Maximize Efficiency with Peak Power and i²t Protection

In today’s fast-paced industrial and rail environments, the demand for reliable and efficient power conversion systems is ever-increasing. Engineers and industry professionals are constantly seeking solutions that not only meet but exceed their expectations in terms of performance, durability, and safety. At Premium PSU, we specialize in providing top-tier DC/AC inverters that are designed to handle the most demanding applications. In this article, we delve into the critical concepts of peak power and I²t protection—two features that set our products apart in the market.

What is peak power and why pay attention to it?

Peak power refers to the maximum power output that an inverter can provide for a short duration to manage sudden spikes in demand. This capability is essential in applications where the power requirements can fluctuate dramatically, such as in industrial machinery, equipment with motors, transformers, contactor or any device with high inrush current.

Key Benefits of inverters that manage power peaks

Flexibility: Allows systems to handle load variations without needing to oversize the inverter, saving on costs and space.
Cost-Effective Solutions: Reduces the need for larger, more expensive systems by ensuring that the inverter can meet temporary high-power demands.
Reliability: Ensures continuous operation during peak load conditions, maintaining system stability and uptime.

Types of overload protection for managing power peaks

Current limitation: Is the most used for DC outputs. May be complemented with a second limit threshold timed to supply peak power.
Overcurrent shutdown: Is the most used for AC outputs. May be complemented with a second limit threshold timed to supply peak power.
Thermal shutdown: Is more a complementary protection for long time overloads.
I²t shutdown: Is the best protection for DC/AC inverters

What is I²t Protection and why is the best one?

I²t protection is a type of electrical protection used in power distribution systems to protect equipment such as motors, transformers, and other electrical devices from overcurrent. It is based on the concept that the energy dissipated in a conductor due to an overcurrent is proportional to the square of the current multiplied by time (I²t).

Advantages of I²t Protection

Increased Safety: Protects both the inverter and the connected loads from potential damage due to excessive currents.
Longer Lifespan: Minimizes wear and tear on components, extending the life of the inverter and the overall system.
Selectivity: Allows the selectivity of the protections of a downstream line to be calculated.
Customizable Settings in Premium inverters: Allows engineers to set specific current limits via communication port, offering flexibility in system design and operation.

At Premium PSU, most of our standard DC/AC inverters are equipped with I²t protection, current limit and thermal shutdown. This ensures the delivery of maximum energy to the load without risk to the load or the inverter itself.

Example:

Power range of ODX-3000 series

3000 W continuously
4500 W for 5 seconds
6600 W for 1 second

Peak Power and I²t Protection

Combining peak power capabilities with i²t protection creates a robust power conversion system that can handle the most challenging conditions. This synergy ensures that your systems can not only meet but exceed performance expectations while maintaining the highest safety standards.
