When selecting a control output, use the H3Y-2 for switching ON
and OFF the power and the H3Y-4 for switching ON and OFF the
minute load.
The operating voltage will increase when using the H3Y in any place
where the ambient temperature is more than 50°C. Supply 90% to
110% of the rated voltages (at 12 VDC: 95% to 110%) when operating
at 50°C or higher.
Do not leave the H3Y in time-up condition for a long period of time
(for example, more than one month in any place where the ambient
temperature is high), otherwise the internal parts (aluminum electrolytic
capacitor) may become damaged. Therefore, the use of the
H3Y with a relay as shown in the following circuit diagram is recommended
to extend the service life of the H3Y.
