What does Phase cut mean?
What does Phase cut mean?
“Phase-cut” dimmers work by taking the line input power (120V “house power”) and modulating the signal to reduce the power to the load. By “chopping” the signal, the load experiences a lower voltage, resulting in a lower light output.
What are the two types of phase cut dimming?
Phase-cut dimmers can operate on the leading edge (forward phase-cut) or trailing edge (reverse phase-cut) of the waveform.
What is phase cut dimming?
The phase-cut dimmer was designed as a simple, efficient, and inexpensive method to dim incandescent light sources. It operates by limiting the power delivered to the load, only conducting a certain percentage of the AC mains each half-cycle.
What is phase cut driver?
Phase cut dimmable driver is a TRIAC based LED Driver and it is a constant current (CC) LED Dimmable driver.It can be Dimmed with any Home Automation as well as Dimmer (Regulator). It is Compatible with both Leading and Trailing edge home automation.
What is the difference between 0-10V and 1 10V?
The main difference between 0-10V and 1-10V is the direction of the current between the dimmer and the driver. 0-10V conduction at 0.3V;When 1-10 V is turned on at 0.7-0.8 V, the bulb will not be able to turn off completely.
How does a 0 10 volt dimmer work?
0-10V dimming is a lighting control method that – on direct current voltage (DC) between 0 and 10 volts – can produce light at varying intensity levels. At 0 volts, the light will dim to its minimum light level, although sometimes a switch is required to turn the lights off completely.
What is RC dimmable?
Electronic wall dimmers, which are based on the so-called trailing edge principle, are compatible with dimmable LED lamps. Electronic wall dimmers are marked with the letters RC. Trailing edge dimmers are electronic dimmers, which are marked with RC or RLC.
What is the difference between 0-10V and 1 10V dimming?
What is a phase selectable dimmer?
The phase-adaptive dimmer controls a wide variety of bulbs by automatically sensing the load type and adjusting to provide the best performance. Because of the dimmer’s flexibility, you’ll be able to change your lamp without changing your dimmer.
Is 0-10V dimming AC or DC?
0-10V dimming is a lighting control method that – on direct current voltage (DC) between 0 and 10 volts – can produce light at varying intensity levels.
How does a phase cut dimming system work?
The phase-cut dimming system operates the dimming function by controlling the period of AC power that flows into the system, meaning that the power being input from the main electricity within a wave cycle controls the brightness of lamp. This is what we called PSR (primary side regulation).
What is reversereverse phase-cut dimming?
Reverse phase-cut dimming was developed to improve performance of low voltage halogen lamps operating on an electronic transformer, a type of switch mode power supply.
What is the load capacity of a phase-cut dimmer?
Phase-cut dimmer loading • Minimum load varies by dimmer and LED source • Maximum load varies by dimmer and LED source • Overloading can lead to premature failure Dimmer Source Possible loading 600W incandescent 60W incandescent 1-10 600W incandescent
How does a half wave cutting device work?
All of these devices work by cutting off part of each half cycle of the AC line waveform. The amount that’s cut off is measured by the phase angle. A complete sine wave is 360 degrees in length; a half wave is 180 degrees.
