2 Definitions
This section uses the following definitions. The definition used "voltage" and "current" Unless otherwise specified, refer to RMS (r.m.s).
2.1 voltage, current, frequency and power ratings related definitions
Manufacturers controller specified voltage, current, frequency or power. Three-phase power line voltage is rated voltage.
Manufacturers of a range of voltage, current, frequency or power control provisions of the above limit and lower limit represented.
When the device is supplied at rated voltage, maximum valid any DC or AC voltage generated on a particular insulating member in the device.
Note 1. transient overvoltage negligible.
Note 2. Consider the open circuit conditions and normal operating conditions.
Between the wire and between the wire and does not exceed the nominal voltage of 42V; or three-phase connection, no more than 42V between the cables and conductors
Does not exceed the nominal voltage of 24V between the conductor and the midline.
Between conductors and between conductors and ground does not exceed 42V nominal voltage between conductors; or in three-phase circuit, does not exceed between conductors and neutral
Over 24V, no-load voltage of the circuit does not exceed 50V and 29V, respectively.
When safety extra-low voltage is a higher voltage from the mains supply, it should be through a safety isolating transformer or equivalent insulation around alone
Group converter.
Note. The voltage limit is based on the assumption that the safety isolating transformer at rated voltage on.
In Canada and the United States, safety extra-low voltage limit is 30V.
Between the input winding and output winding through at least equivalent to double or reinforced insulation in electrical insulation will separate them, and
And it is intended to be used as a safety extra-low voltage circuit power supply transformer.
The relationship between the live parts, interconnections between them can be a current through the load, and the current to the load it is limited.
Relations between the two charged components, interconnection between them can make the current through this current by the impedance of the power supply circuit to limit.
The maximum capacity of 100VA isolation transformer secondary winding circuit leads, and secondary open-circuit voltage rating not exceeding
Operating level, in this final operation of the electric load by the auxiliary device such as a relay or the like contactor control.
Oscillation or oscillation damping is usually high, the duration of only a few milliseconds or less short-term over-voltage [IEV604-03-13].
By the manufacturer of the equipment or its components selected impulse withstand voltage value, to characterize its anti-insulation specified transient overvoltage tolerance.
Transient represented by numbers overvoltage conditions.
NOTE. Use the Ⅰ, Ⅱ, Ⅲ and Ⅳ represented overvoltage category. See Appendix L.
2.2 is defined by use classification controller
In conjunction with the device or the device, and means for changing the output device, comprising excitation, transmission and three operation portions, wherein at least
There is a part of the electrical or electronic.
One kind of excited by the starter and controller, its transmission and operations are done directly, without any intentional time delay.
Excitation, and transfer operations at least a portion of the non-manual control.
An automatic controller, which is excited by a special start of the stated amount, including the amount of these special starting temperature, current, humidity,
Light, level, position, pressure or a speed-sensitive element to complete.
A progressive automatic controller transfers heat from the original mechanism.
A cyclical temperature sensing controls, which under normal operating conditions to maintain the temperature between two particular values, which can be and
There are set by the user of the device.
