Mounting Dimensions

Product Features:

◎The SCR unit attached with high speed fuse in order to prevent the damage of SCR due to the    shortage current (di/dt).
◎The unit is packagecd onstruction with less dimension, easy for installation and wiring
◎The causes of malfuntion can be indicated by individual LED lamp, easy for trouble shooting.
◎Less non-linearity output provides accurate control of temperature.
◎High quality and high technical productions with no electrical interference.
Operation Enviroment:
 ◎Ambient temperature:-10~45℃,Relative humidity: Max 90%
Installation: 
◎The SCR unit will produce heat itself during operation, piease errect it
   upward accrding to the instruction.
◎The panel must be upward ventilated for hot air. we recommand 
   mountiong a ventilating fan in the control panel.
◎Do nor install the unit in the space with high temperature and poor 
   ventilating, Do not operate the unit exceed 70% of rated output in
   case of above mentioned poor ambient  conditions.
Load Test:
◎The SCR unit will not well funtioned in case of less output load(0.6 Amp).
   Please connect the load at least 0.6 Amp.
