A programmable timed electrical power management device protects and controls electrical equipment and peripherals which are plugged into it. The front of the housing containing the electrical circuitry is provided with a LCD display, a series of pressure sensitive switches for inputting function and control commands to control the operation of the device. A series of LED's mounted on the front of the housing indicate the operational status of the device. The back of the housing is provided with an AC power input receptacle, an on/off reset switch, a series of AC outlets which are divided into pairs of filtered banks, and two or more modular jacks for receiving the modular plug of a telephone, fax, and/or modem. The device circuitry includes a CPU, timer/calendar, a sound generator, voltage sensors, and a back-up battery power supply. The outlets and modular plugs are protected from electrical surges. Each bank of outlets can be selectively programmed to turn on and off at a different time of the day and different days of the week. When more than one bank is set to start at the same time, power is sequentially supplied to each electrical outlet bank allowing the voltage to stabilize before turning on the next bank. A warning tone will sound fifteen, ten, and five minutes prior to shutting off any of the banks, to alert the user that the system is approaching the preset time for the power to the outlets to be turned off, to prevent accidental loss of information. 9 figs.
