PROBLEM TO BE SOLVED: To provide an inverter adaptable to environmental conditions, along with easy maintenance, and produced in a simple manufacturing step at low cost. SOLUTION: An inverter part is mounted on a circuit board. The inverter part is made up of a power element 21, a driver circuit 22 for driving the power element 21, a control circuit 23 that includes a CPU for controlling the driver circuit 22, and an interface circuit. The board with the circuit is molded in a body with resin. Only input/output lines and an interface terminals are taken outside from the sealed molded body. |
