For different voltage application environments, we recommend the following pressure sensitive combinations to
provide over voltage, surge and lightning stroke protection for ACLED.

For users in Indian and Brazil
Since pressure sensitive resistor is easy to degrade under the environment with strong voltage fluctuation,it is required to
select the combination with high pressure sensitive voltage value as much as possible under the premise that withstand
voltage of IC(MOS tube)+lamp bead on lamp board is pretty high and that voltage has a large fluctuation area.besides,it is
necessary to select pressure sensitive resistor with large drculation and volume as far as possible,without exceeding cost
limit.

Notice for use
To avoid damage to other equipment due to fire or deterioration caused by varistor, please refer to and
observe the following principles:
1) When a high current or high voltage flows into the varistor, the varistor itself may be damaged, heated,
smoke, catch fire and burst.
To avoid this, fuses or circuit breakers can be installed at both ends of the varistor or power supply;
The fuses of the following specifications are for reference only:
Diameter 05D 07D 10D 14D 20D
Rated current of fuse
1-2A 2-3A 3-5A 3-10A 5-15A
2) Do not allow the current and energy flowing into the varistor to exceed its rated value.
3) The marked VDR product brand names and marks are all patent applications of the company.
Customers who use or sell VDR products that are not specifically designated for such applications are at
their own risk.
4) All VDR products, product specifications and data are subject to change without notice, please
improve. For any data sheet Or any other data sheet. Any errors included. Inaccurate or incomplete shall
not be liable.
