5-1-2(C) FUNCTION OF BOARD
(1) Remote control
Using 250V/ 10A relay, the board makes remote control available.
(2) Free voltage
The board designed so that input voltage can be used within 90 VAC to 264VAC.
(3) Embedded thermal sensor
The board is equipped with thermal sensor to detect the internal temperature of the unit, and to short
relay when the internal temperature is higher than specified temperature so as to shutdown the unit.
(4) Improvement of power factor
The board is designed using PFC circuit so that PF (Power Factor) can be over 0.95, because low PF
can be a problem in high voltage power.
(5) Protection
The OCP (Over Current Protection), the OVP (Over voltage Protection), and the Short Circuit
Protection functions are added against system malfunction.
