6.1  動作概要  Outline of Function 

この基板は、

80W

型フリーピストンスターリングクーラー

(FPSC)

を接続し、下記の機能を有します。

 

This PCB is designed to operate in conjunction with a 80W Free Piston Stirling Cooler (FPSC) and has the 

following functions. 

(1) DC24V を電源入力とし、80 Hz の PWM 波形を出力することで FPSC を駆動します。 

To drive FPSC with 80 Hz PWM output, with power inverted from 24 V DC input power. 

 

(2) FPSC

の駆動電圧は、所定の端子に電圧(

DC 1

5V

)又は、電流(

DC 4

20mA

)を入力することにより

決定されます。

 

To  provide  the  desired  drive  voltage  to  the  FPSC,  the  drive  voltage  is  decided  by  the  input 

voltage (1- 5 V DC) or input current (4 - 20 mA DC) to the control terminal. 

 

(3) FPSC

運転開始直後において、

FPSC

の駆動電圧は

DIP SW

で設定された速度で段階的に上昇しま

す。

 

After initial start up of the FPSC, the driving voltage increases in steps at a speed determined by 

the DIP switch settings. 

 

(4) FPSC

への出力電流が

DIP SW

で設定された値を超えないよう、出力電圧を制限します。

 

Control  the  output  voltage  in  order  to  limit  the  output  current  to  the  FPSC  not  to  exceed  the 

value set by the DIP switch. 

 

(5) FPSC

が動作中に、ファンモーターへ電圧を供給します。

 

While FPSC is working, it provides voltage supply to the fan motor. 

 

(6) 

次の状態検出時に、所定の端子より異常信号を出力し、

FPSC

の動作を停止します。

 

The  PCB  outputs  an  emergency  signal  and  stops  power  output  to  the  FPSC  when  following 

conditions are detected

 

①排熱側温度センサーの温度が、

DIP SW

で設定された温度に達した。

 

When the temperature of the sensor on the warm side reaches the temperature set by the 

DIP switch.

 

FPSC

が接続されていないか、又は、断線した。

 

When the FPSC is disconnected or the input power wire is cut.

 

③温度センサーが接続されていないか、又は、断線した。

 

When the temperature sensor is disconnected or wire is cut.

 

④入力電源電圧が範囲外である。

 

The power source voltage is out of allowable range.
