A programmable electronic start-up delay for delaying the start-up of refrigeration units (10, 12, 14) for a user-programmable variable delay period. The delay permits a group of refrigeration units all powered by the same source (16) to be restarted at different time intervals after a power failure

A programmable electronic start-up delay for delaying the start-up of refrigeration units (10, 12, 14) for a user-programmable variable delay period. The delay permits a group of refrigeration units all powered by the same source (16) to be restarted at different time intervals after a power failure to prevent overloading of the power source or associated circuitry.

[ Having thus described the preferred embodiment of the invention, what is claimed as new and desired to be protected by Letters Patent includes the following:] [1.]1. A method of controlling start-up of an electrically powered device, the method comprising the steps of:(a) receiving a delay value in an electrical signal from an input device and storing the delay value;(b) detecting a disruption of power delivery to the electrically powered device;(b) detecting a resumption of power delivery;(c) measuring a period of time following resumption of power delivery, the length of the period of time being determined by the delay value; and(d) preventing start-up of the electrically powered device until after the period of time has been measured following the resumption of power delivery.
