Product Description:
intelligent photoelectric deadbolts Adoption of new IR photo-detecting elements enables precise positioning of doorway and locking of lock cylinder. It retracts lock cylinder before locking completely to protect the lock cylinder from abnormal damage. A buzz is generated either when lucking is completed or luck cylinder is not retracted well. The binal-signal input with digital/ dry contact allows digital/ regular card readers to operate the deadbolt. It comes with ultra-light LED to show the status of power and operation. Setting of each function can be operated by its IR remote

Product Description:
(1) If capacitor is installed in circuit with harmonics, normally it should be equipped with 6% series reactor. For circuit with significant 5th harmonic, it should be equipped with 8% series reactor. For the circuit with 3th harmonic, like arc furnace, it should be equipped with 13% series reactor. For the capacitor installed as non-fixed use, it should be equipped with 6% series reactor. (2) If the capacitor used with reactor, its rated voltage should be increased 15% - 20% to insure safety and extend life-time of capacitor. (3) For more questions about the installation and other applica

1. Self-Healing : Dielectric adopts metallized polypropylene as in-between material ; in case excessive voltage takes place and damages the in-between material, the metallized film around the damaged spot will disappear instantly, and insulation is restored immediately. 2. High Safety Control : In case of abnormal situation happened either on line or on capacitor itself, the built in protective device will act and cut off the power supply automatically, hence avoid the relative disaster. The outer box is made by noncombustible plastic projection, conforming UL 94V-O standard. 3. Minimu
