LPS® DL Series
They protect equipment with high-speed signal or higher bandwidth with working voltages of 7.5 V and 24 V
The LPS® DL Series are reliable surge protective devices specially designed for systems using screen cable plus equipment with screen terminal for high baud rate data transmission. They are ideal for RS 485, RS 422, RS 423, Ethernet signal of instrumentation interfaces and equipment which include servers, Card Reader Controllers, lift controllers as well as twisted pair CCTV circuit. They provide unsurpassed performance in lightning surge protection.
How they work
The LPS® DL Series devices are manufactured in Malaysia with multi-stage protection. Primary protection starts with GDT (Gas Discharge Tube) which is then supported with a second-stage surge attenuate component network and finally to a semiconductor voltage dependent device. These devices deploy state-of-the-art engineering technology with high surge capacity to protect sensitive data networks effectively even in the most lightning prone regions in the world. All this is done without impairing the system’s normal operation or cause excessive in-line resistance.
When surges occur, these devices will switch to a fully conductive state and divert surge current, after which it will reset automatically. However, under excessive surge conditions, the LPS® DL Series devices will fail in shorted mode to earth, securing the protection of the equipment.
For more effective protection, we highly recommend that the LPS® DL Series devices be installed at both ends of the cable, especially when the connecting equipment is located 30 metres away, in an adjacent building or outdoors. The cable should not exceed 75 metres for optimal performance at 100 MHz transmission rate. All equipment and SPD earth must be linked to the system’s common earth.
