The contents of changes
The changes of AC/DC power supply and terminal block, builtin dehumidifier. (refer to chart1 and chart2)
※For general purpose type “RDH-3J1”, only terminal block to be changed.
Chart.1 Before the changes (present product)
3. The reason for changes
Due to production discontinuance at power supply manufacturer (COSEL.CO.JP).
4. Due to the changes, the influence on products
（1）The function of power supply
Though the power supply manufacturer and the specifications are partially changed, the
conventional functions are covered. Thus, it can be used as ever. (*We confirm that there
is no operational difficulty at our advance verification.)
In addition, as for 4 models, RDH-10J1、RDH-10J2、RDHC-10J1、RDHC-10J2, the input
voltage range is from “AC85～132V” to “AC85～264V”, it can be used abroad as it is.
（2）The position of LED
As for 4 models, RDH-5J1、RDH-7J1、RDHC-5J1、RDHC-7J1, the installation position of
LED is changed. (chart 1, chart2) In addition, to be installed on the housing cover directly,
therefore it is a protruding structure a little. (chart 3)
（3）The terminal block
The pitch of a screw is almost the same as conventional one and it can be connected as
ever. In addition, we change into the type which is easy to install and reinforced.
Consequently, the external dimension is changed. For further details, please refer to below
dimension difference from set plate. (chart 3)
Chart.3 The dimension difference from set plate (back plate)
(4) The installation dimension
The external dimension of dehumidifier body (excluding terminal block part) and the installation dimension secure the compatibility with the present product. (*The installation dimension has no change)
(5) RoHS-compliant
