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. |
