说明/Description
① 一些如碳硅棒等特殊负载应用：低温时负载阻抗很小，加热升温，温度超过 700～800℃后阻抗增大；
如果刚开始时用过零控制调功方式则对电源冲击会很大，也会使碳硅棒使用寿命大大缩短，所以开始阶段
使用相位控制移相调压方式，加热升温，温度达到一定值后转换为过零控制调功方式，使电源功率因素提
高，减小调压所带来的谐波干扰/Special load such as carbon silicon rods application: when temperature is low
load resistance is small, with temperature raises over 700-800 degrees, the load resistance will increase, the
lifecycle of carbon silicon rods will be reduced significantly, so during start-up stage please use phase control
voltage adjustment until temperature reaches certain level then switch to zero control in order to improve power
factor, reduce harmonic interference from surge
② 用相位控制移相调压方式给变阻性负载加热时推荐使用带恒流方式的电流反馈机型，控制效果最佳/Use

4、有无反馈说明/Have no feedback description

的危险

fire hazard.
七、安装调试
■ 安装注意事项/Caution when installing
● 控制器应在推荐的工作环境下使用
The installation and usage of the equipment should be done under the suggested working conditions
● 控制器应采用壁挂式竖直安装，有利于通风散热
The regulator should be installed vertically to ventilation and cooling.
● 严谨猛力撞击控制器
Do not expose the regulator to any vibration or shock directly
● 电源电压不要超过工作电压±10%范围
Power supply could not exceed 10% of the working voltage
● 模拟量输入值不要超过控制器的输入信号范围
Analog quantity input could not exceed the input signal range of the regulator
● 反馈输入电压值和电流值不要超过工作电压和额定电流范围
Input voltage feedback and current feedback should not exceed the working voltage and rated current
● 带通讯的控制器外部接线建议使用屏蔽线
Controller with communication capability should use shield line for external wiring
■ 系统接线及调试 /Wiring and debugging
● 仔细检查各接线是否正确，端子是否拧紧后再给控制器通电，调试时负载端不允许开路或空载，否
则调试工作无法正常进行
Go through all the wiring and terminals before power up the regulator. During commissioning, zero load or
short circuit is prohibited
● 为了调试工作顺利、可靠的进行，一般电压反馈控制的触发调压器、电流反馈控制的触发调流器等
可先用小负载(1只200W 灯泡或几百瓦的加热管等)进行通电调试，正常无误后再接入实际负载
In order to ensure commissioning is smoothly and reliable, trigger of voltage feedback control and current
feedback control should be adjusted to minimum load (200W bulb 1 or hundreds watts heating pipe), to
ensure working properly before connect actual load
● 当调节面板▽和△键、给控制器控制信号端输入正确的控制信号、旋转手动限幅电位器时输入信号
逐渐增大或减小，负载上的电压应随输入信号变化而变化，负载上的电压调整范围为 0～100%
When adjust ▽ and △ key on panel, input control signal from controller, or rotate the limiter of
potentiometer input signal increases or decreases, load voltage should follow change of input signal, load
voltage should be within 0～100%
● 负载上的电压变化应平滑、均匀、连续，不应出现突跳、抖动或变化趋势与输入信号不成线性关系
等的现象
Change of load voltage should be smooth, continuous, sudden jump, shake or trend should be avoided to
prevent non-linear behaviours
● 在控制器通电状态下显示器数据区域出现出错代码提示信息，用户在控制器未断电状态下检查完线
路等情况确认无误后需给控制器重新上电方能进入待机状态或工作状态，如果无出错代码提示则可
以正常工作输出，如果输出部分电压(流)后仍然出现出错代码提示信息则需要用户再次检查线路，
重复如上操作
Error code and messages are displayed at data area of controller, users should recycle power to force
controller into standby or operation mode after error is checked. If there is no more error message then
normal operation shall be resumed. If error still occurs, please repeat the process
■ 可控硅小知识/SCR tips
● 断态、反向重复峰值电压：一般取负载电压有效值的三倍以上，例如：AC220V 供电的负载，可控硅
的峰值电压应大于 AC800V；AC380V 供电的负载，可控硅的峰值电压应大于 AC1200V
Peak repetitive off state voltage and peak repetitive reverse voltage: Normally use a value more than three
times of the effective value of the load voltage, for example: for load voltage with AC220V, SCR peak
voltage should be more than AC800V; for lad voltage with AC380V, SCR peak voltage should be more than
AC1200V
● 门极触发电流：一般选择 60～150mA 之间，门极触发电流太小，容易引起可控硅误触发；门极触发
电流太大，容易引起可控硅输出小电流时出现打不开现象
Gate trigger current: Normally choose between 60～150mA. If the gate trigger current is under the value,
the SCR can be mis-triggered easily. If the gate trigger current is over the value, SCR output current can not
be opened
● 门极触发电压：一般应小于 2V Gate trigger voltage: < 2V
● 通态峰值电压：通态峰值电压越小越好，通态峰值电压越小则发热量越低即可控硅损耗越小
Peak forward on-state voltage: the lower the peak forward on-state voltage value the better as lower value
of the peak forward on-state voltage means less heat and less loss
八、不同类型负载的控制方法
■ 感性负载(变压器等)/Inductive Load (transformers etc)
● 如果变压器设计的输出容量不足，则会造成当电流增加到一定程度时变压器铁芯会发生磁饱和现象，
导致电流瞬间剧增、输出波形发生畸变、导致器件被损坏，解决方法：1、重新设计变压器，需增大
变压器的输出功率；2、增加负载上最大电流限制功能
Shortage in the transformer design output capacity will result in the magnetic transformer core saturation
phenomenon when the current reaches a certain level, an instant surge current, the output and waveform
distortion will occur which lead to device damage, the solution: 1、re-design transformers, need to increase
the output power; 2、increase the maximum load current limit
● 当变压器负载运行过程中断电瞬间后又上电，会造成上电时的通磁极性与断电时未退完的剩磁极性
(上电时正在充磁和断电时正在退磁)发生“撞车”，产生危害性冲击电压、电流，所以电感性负载尤
其是变压器负载，应采用上电软启动逐步充磁和缓停功能逐步退磁操作
When power lost occurs during operation, it will cause through magnetic polarity during power-up and
power outage did not retire completely remanence polarity ( when the power is off when the magnetization
and demagnetization are ) cause "crash",It will have impact on voltage, current, and inductive load,

transformer load should be used on electric soft-start gradually magnetization gentle stop function
gradually demagnetization operation
● 变压器负载为感性负载，窄脉冲触发不可靠，脉宽可变直流触发技术能够提供负载电流到达晶闸管
擎住电流所需的足够时间和能量，确保触发的可靠性
Transformer load is inductive load , short pulse trigger is unreliable , pulse width triggering technology
provides variable DC load current reaches the thyristor Latching current which requires for sufficient time
and energy to ensure the reliability of the trigger
● 变压器负载不能空载调试、工作运行
Zero load must be prohibited for commissioning and operation for inductive load
■ 变阻性负载(泛指冷、热状态电阻值变化大的负载)/Variable resistive load (refers to cold, hot state
resistance change large load )
● 纯金属负载：硅钼、钼丝、钨、白金、石墨等负载冷态时电阻小，低温、中温段需限压、限流，随
着温度变高，电阻随温度一起增大，在高温段时由于电阻较大需增加电压方能使负载工作在恒流状
态，PKC1 功率调整器的电流限制功能和恒流功能是专门为这类负载设计的；此外，带多路 PID 调节
的温度控制仪表也可根据温度变化来控制负载电流
Pure metal load : Silicon molybdenum, molybdenum wire , tungsten , platinum , graphite and other loads
when cold resistance, low temperature, temperature segment need limited pressure , current limit , as the
temperature increases, the resistance increases along with the temperature in the high temperature section.
This is due to larger resistance can the need to increase the voltage in the constant-current load status ,
PKC1 power regulator and constant current limit function is designed specifically for the type of load; in
addition , with multi-channel PID regulator temperature control instrumentation but also according to
temperature changes to control the load current
● 硅碳棒负载：一般采用软启动时间＞60s 或更长、采用电流限制功能，避开在 700℃附近时的负阻冲
击电流(新棒更明显)
Silicon carbide load : Usually soft-start time > 60s or even longer , using current limit function , to avoid
the negative impact of the current resistance near 700 ℃, the (more effective for new rod)
■ 定阻性负载(泛指冷、热状态电阻值变化小的负载)/ Fixed resistive load (refers to cold, heat a small
change in the status of the resistance load )
● 定阻性负载可采用变周期调功方式，可以克服调压方式功率因素低、电网被污染的缺点，PKC1 功率
调整器工作在过零控制变周期调功方式时负载电流以全正弦波为单位均匀分布，多台设备同时运行
时，总动力电流相对均衡，解决了定周期调功方式工作时电流过度集中问题，改善了炉温均匀性，
避免了电流表撞针，更重要的是提高了电源利用率和避免了电力设备增容，节电效果十分明显
Shift period for fixed resistive load adjustment method should be used , low voltage mode power factor ,
the disadvantage grid contaminated could be overcome, PKC1 power regulator operates in the chirped way
power adjustment method of the zero crossing control with full load current sine wave units evenly
distributed , multiple devices to run simultaneously , the total current is relatively balanced to solve the
power adjustment when given cycle work as the excessive concentration of current problems and improve
the temperature uniformity , avoiding meter striker , more importantly, to improve the power utilization
rate and avoid power equipment capacity increase , energy-saving effect is very obvious
