Core txhais
Lub hwj chim regulator yog ib qho khoom siv hluav taws xob uasprecisely tswj lub hwj chim muab los ntawm lub hwj chim qhov chaw mus rau lub load. Los ntawm kev kho qhov voltage, tam sim no, los yog waveform, nws phim lub zog load rau preset tus nqi, tsis txhob siv hluav taws xob pov tseg thiab cov khoom puas tsuaj los ntawm kev tswj tsis tau lub zog. Nws cov ntsiab lus tseem ceeb tsis yog kev hloov pauv hluav taws xob nkaus xwb, tab sislub refined tswj ntawm fais fab kis efficiencyhloov mus rau txawv load yuav tsum.
Cov ntsiab cai ua haujlwm tseem ceeb
Phase Control (Phase-Tshwj xeeb Voltage Regulation)
Centered ntawm silicon-tswj rectifiers (SCR) / TRIAC, nws pom qhov xoom- hla qhov taw tes ntawm AC lub zog thiab ncua sij hawm lub cim mem tes (kho lub kaum sab xis). Qhov loj dua lub kaum sab xis conduction, qhov qis dua qhov ua tau zoo ntawm qhov hluav taws xob thiab lub zog nkag mus rau lub nra; conversely, lub zog nce. Nws tsis hloov qhov zaus, tsuas yog kho lub waveform lub voj voog, haum rau AC systems.
PWM Pulse Width Modulation
Siv lub siab -kev hloov pauv ceev xws li MOSFETs thiab IGBTs, lub voj voog tau hloov mus rau thiab tawm ntawm qhov muaj zaus los kho lub luag haujlwm ntawm lub siab - theem pulse hauv lub voj voog. Lub luag haujlwm lub voj voog txiav txim siab nruab nrab lub zog: qhov loj dua lub luag haujlwm lub voj voog, lub zog siab dua.Nws ntaKev ua haujlwm siab heev (ntau tshaj 80% -95%), ua rau nws lub ntsiab technology rau precision khoom thiab lub zog -txuag daim ntaub ntawv.
Cycle Control (Xoom-Crossing Trigger)
Lub hwj chim yog tswj los ntawm kev tswj tag nrho - voj voog conduction los yog txiav tawm siv tag nrho AC cycles li chav tsev, kho qhov piv ntawm conduction cycles. Nws tsim cov kev cuam tshuam me me heev thiab nyiam rau daim phiaj- cov khoom hnyav hnyav (xws li cov cua sov).
Main Classifications thiab Features

- Cycle-Control Power RegulatorRaws li xoom- hla lub voj voog tswj.Qhov zoo: tsis tshua muaj kev sib haum xeeb, kab sib chaws- phooj ywg.Applications: purely resistive loads (hluav taws xob furnaces, ncu), ntev -lub sij hawm ruaj khov cua sov.
Core Values
- Precise kub / ceev tswj: Sib tw tswj cov teeb liab xws li 4–20mA thiab 0–10V kom ruaj khov cov txheej txheem tsis.
- Mos pib / mos nres: Smooth startup thiab shutdown txo inrush tam sim no thiab txuas lub neej kev pab cuam ntawm cua sov ntsiab thiab motors.
- Kev tiv thaiv ntau yam: Integrate overcurrent, overvoltage, overheating, and the phase-poob kev tiv thaiv kom txo tau cov khoom tsis ua hauj lwm.
- Kev txuag hluav taws xob: Cov khoom siv hluav taws xob raws li qhov xav tau, txo qis kev siv hluav taws xob tsis zoo, thiab txo cov nqi khiav lag luam.
Cov ntsiab lus
Lub hauv paus kev sib tw ntawm lub zog regulators nyob hauv"Kev sib txuam meej + kev ua haujlwm siab thiab txuag hluav taws xob".
Rau kev xaiv kom raug, qhov tseem ceeb yuav tsum tau muab rau kom meej meej hom load (resistive / inductive / capacitive), ntsuas lub zog, thiab qhov hluav taws xob, tom qab ntawd xaiv txoj kev tswj kom tsim nyog thiab hom kev ua haujlwm raws li kev sib haum xeeb thiab cov lus teb ceev, kom ua tiav cov khoom siv thiab cov txiaj ntsig kev lag luam.
