Isolating electrical components

A method, comprising:

• isolating, using an isolating component, electrical components that consume greater than a threshold level of power from electrical components that consume less than a threshold level of power;
• converting an alternating current (AC) signal to a direct current (DC) signal;
• dividing a voltage, using a voltage divider that is coupled to a rectifying component;
• filtering the voltage and comparing the filtered voltage to a reference voltage;
• and
• powering on the isolating component and the electrical components that consume greater than the threshold level of power when the filtered voltage is lower than the reference voltage.

An apparatus, comprising:

• a controller, including a processing resource coupled to a memory resource, the processing resource to execute instructions stored on the memory resource to cause the processing resource to:
• control a timing of a filtering component;
• set conditions that will deactivate a signal that indicates an alternate current (AC) power is of a value that can properly power a system;
• compare a filtered voltage to a reference voltage;
• and
• signify that the AC power is of the value that can properly power the system when the filtered voltage is higher than the reference voltage.
