Abstract: A circuit breaker with overload and short-circuit protection functions for a motor, on which is mounted a thermally actuated overload tripping device including an adjustment dial to set a value corresponding to a rated current value of the motor on a scale. The dial has a standard setting pointer mark and a correction setting pointer mark side-by-side along a perimeter. The standard setting pointer mark applies to using the circuit breaker as a single item. The correction setting pointer mark applies to using a number of circuit breakers arranged in a line in close contact with each other. By setting a mark selected according to the arrangement of the circuit breaker at the rated current value, the steady state current value of the tripping device can be adequately set to correspond to the rated current value of the motor.

Abstract: The invention makes it possible to secure a maximum output within the capacity range of an electrical power source by preventing an output from being cut by a protective function of a converter at the time of a temporary overload. A bidirectional DC-DC converter 4 for stepping up a voltage of DC power supplied from a battery 5 is provided. A stepped-up DC power is converted to an AC power by an inverter 3-2 via a regulator 3-1 and is outputted to the load side. An input voltage V1 of the regulator 3-1 is detected by a voltage detecting portion 15 and is inputted into an output limit determining portion 16. The output limit determining portion 16 determines an output voltage value for starting to limit an inverter output according to a distance from when the input voltage V1 fell below a limit starting voltage value Vlim to a limit voltage value Va. An inverter driving portion 17 limits an output by switching FETs in the inverter 3 in accordance with this output voltage value.

Abstract: A first primary winding N11 of a transformer 1 is connected with a commercial power source 30 via a transistor Q1, and a second primary winding N22 of the transformer 1 is connected with a backup battery 31 via a transistor Q2. An electric power on the second primary winding N12 is output for a controlling apparatus. When a voltage of the commercial power source 30 is larger than a predetermined value, a backup stopping circuit 10 turns off a LED 9 and stops the transistor Q2. The second primary winding N22 is connected with input terminals 14, 15 as a power source for charging a battery 31. While the transistor Q2 is stopped, an electric power for the battery is output from the second primary winding N22. Since the LED 9 turns on at the time of electric power breakdown, the electric power for the battery is stopped.

Abstract: A cogeneration system that is operated in system connection is disconnected from the system and operated independently at a power failure of the system. A power generator 1 driven by an engine E is connected to a system 9. A water-cooling device 13 recovers exhaust heat of the engine E. When an operating switch 20 is switched, to its independent operation mode for an independent operation apart from the system 9, the upper limit of the target rotation speed Ntgt of an electronic governor 16 is increased over that at system connection operation, thereby the engine speed can be increased, and the maximum output point of the power generator 1 is increased for operation.

Abstract: This invention realizes control without using a current-detecting element to prevent over current from flowing into a switching element of a switching converter in response to an input primary voltage from a small-capacity DC power source. The switching converter includes an FET 30 that turns the input primary voltage from the DC power source 1 on and off, and a choke coil 31 that is charged or discharged according to turning on/off of this FET 30. A driver 13 drives the FET so that an output voltage detected by an output voltage detector 9 is converged to a target voltage. A means for calculating a current I that flows into the FET 30 based on a duty ratio of the input primary voltage and the FET 30 and the inductance of the choke coil 31. The driver 13 drives the FET 30 at a duty ratio set so as to prevent the estimated current value I from exceeding a permissible current value or stops driving when the estimated current value I is equal to or more than the permissible current value.
