SCR.POWER.REGULATOR

●Product Features

● With a variety of control input signal selection

(4~20mA/0~20mA/0- 5V/0~10V/1~5V /2~10V) switchable choose

● With internal power output manual adjustment and external output

power manual adjustment + automatic adjustment

● Has a fuse open Indicator/load short open indicator (optional) / SCR

overheating(85℃) indicators and abnormal alarm contact

● With load output power 0~100% shows the percentage of

● With load buffer heating time adjustment (1~25 sec)

● Have instant when you start the power resulting in instantaneous

overcurrent protection circuit (SCR fuse is not burned)

● SCR overtemperature or FUSE fuse immediately stop output,when

troubleshooting pending restoration,then buffered output

● Built FAST fuse、protection SCR no damage (fuses and easy disassembly)

● Ultra-high efficiency heat sinks,thermal type fast、good heat dissipation

● Power frequency self-detection,50~60 Hz can be used,without any

selection or switch

● Main power adopt a single standard design 200V~480V within

the scope of the use of either

● Control signal terminal block、european mining detachable terminal

block,replacementcontrol loop can avoid re-wiring

█ Control methods and applicable load

輸出量 Output 控制方式 Control mode	輸出波形 Output wave
輸出量 Output 控制方式 Control mode	10%Output	50% Output	90% Output
相位控制 Phase angie control
零位控制 Zero crossing cotrol

Phase Control:Continuity intersection control，output stability，ammeter does not shake，but every Zhouban Bo will produce harmonics
Applicable load:fixed impedance load、Variable impedance load、IRlamp

Zero control:assigned zero control，minimum resolution1Hz，does not produce harmonics，output ammeter presents jitter state
Applicable load:Fixed impedance load

█ Wiring and Planning Considerations

NFB→ Turn off the power in the repair and maintenance avoid personal contact

MC→ Can cut off the power supply of the load,in power regulator malfunction or when
the temperature is higher than the set too,cut off the power supply In order to avoid high temperature burning equipment or serious accident (to be with temperature controller)

Power Regulator→ Control signal to follow to adjust the output power,to achieve
the desired temperature.the inside of the product

LOAD→ has installed high-speed fuses therefore,no installation of external fuse

● Standard main loop planning: Main Power→No fuse switch→Electromagnetic
    contactor→Power regulator→Load

● When wiring must locking screw: To avoid bad contact high temperatures

● Wiring is completed,must cover panel and secure the cover,in order to carry
    out transmission operation,in order to avoid electric shock or cause a short
    circuit conductive objects have fallen

● Power regulator used,internally generated heat,please be mounted vertically
    on both sides of the need to install and leaving gaps

● Control box with air convection vents need,please follow the hot air from
    under the principle means to vent or exhaust fan installed

● Avoid installing in serious,steam or acid flow,acid,corrosive gases

█ Adjustment function Display and troubleshooting

① VR1 BIAS: Reference output voltage adjustment(counterclockwise to adjust the
                     control signal the smaller input to outpu)
② VR2 MAX: The maximum output voltage adjustment (adjustment range 0~100%
                     counterclockwise adjustment Reduce the amount of full output do not
                     zerootherwise there will be no output)
③ VR3 SFS: Buffer rise time adjustment (adjustment 0~25 seconds clockwise to
                   adjust the buffer between the increase)
④ VR4 R phase: R phase adjustment
⑤ VR5 T phase: T phase adjustment

█ VR-100%: Output Power 0~100% If
not adjust with the need to VR go to full output

█ RESET: Return built (restart)

█ %:Output Power 0~100% display lights

Code	Display status	Abnormal Cause	Countermeasures
P	Power indicator does not light (Light indicates normal)	Auxiliary power is not power transmission PBC board failure	Check the auxiliary power supply circuit PCB version replacement or repair machine
I	Input indicator does not light (Light indicates normal)	TIC output signal is not output TIC output signals of opposite polarity internal MAX VR or external external VR zero	Check the TIC output signal Check internal MAX VR and external VR
