6 FAQs about [Relay coil energy storage]

How do I control the power consumption of a relay coil?

1. Apply overrated coil voltage to the relay coil for 50ms or greater. This is typically around 130% of the nominal coil voltage. 2. Control power consumption when the relay is ON using relay coil resistance, C, and R. 1. Turn MOS-FET ON to apply voltage to the relay coil for a minimum of 0.1s. Ensure MOS-FET is completely ON (Duty ratio 100%). 2.

Which relays can be operated with reduced coil voltage?

Why do I need a relay coil surge suppression?

Relay coil surge suppression may be necessary to prevent component damage during contact release. General purpose diodes provide an easy and inexpensive solution, but they may cause problems due to slowed release times.

What happens if a relay coil is de-energized?

In many basic relay circuits, damage may occur when the relay coil is de-energized. When the power supply is removed, the stored energy in the coil (inductor) reverses polarity and seeks a path for dissipation (current flow). During this time, a large and possibly dangerous voltage potential builds at the component junctions.
