ロクロス電力制御装置。 In this device, a solid state relay 11 is inserted into a load circuit 13 that supplies power to a load 2 from an AC power source 1, and the load power is controlled by turning on and off the solid state relay 11. A current level comparator 9 is provided which compares the output of the current detector 8 with a reference current level and outputs a pulse every time the output of the current detector 8 exceeds the reference current level. A power setting device 6 is provided for setting the number of cycles for flowing the load current in each control period θ, and the output of the power setting device 6 is input and set, and the output of the current level comparator 9 is input every time. A zero-cross power control device is provided with a subtraction counter 12 for subtracting the number of cycles set in 1 by one and turning on a solid state relay 11 until the subtraction result becomes zero.
