Surge Protection Devices

Our range

• Power protection: Class I SPD LP-50A for the transformer side or LPZ0–LPZ1 boundary, Class B LP-75B and Class B+C LP-40B+C for main distribution boards, and Class C LP-20C plug-in modules for sub-distribution, all with status indication.
• Solar and DC: the LP-PV photovoltaic DC SPD at 800, 1000 or 1200 V, and LP-COM/A units for 5–230 V AC/DC supplies.
• Instrument signals: the LP-V series process control protector for 2-wire 4–20 mA loops from 5 to 36 V, and LP-C/TER for RS232, RS422 and RS485 lines on DIN rail.
• Data and communication: RJ45 Ethernet and PoE protectors, RJ11 telephone line protectors, DB9 serial protectors, BNC and F-type video protectors, and LP-TK antenna feeder protectors for GPS, microwave and satellite links.
• Monitoring and testing: the LP-JS lightning counter records arrester discharges, and the LP-TEST108B tester checks MOV leakage and GDT and TVS breakdown voltages.

Applications

• Instrument loops and analyser power supplies
• SCADA, PLC and telemetry communication lines
• Building low-voltage distribution boards
• Solar PV installations
• CCTV and network systems
• Antenna and wireless links

How to choose

• Identify every line entering the equipment: power, signal, data or RF.
• Match the protector to voltage, signal type and connector.
• Protect both ends of long outdoor cable runs.
• Confirm a sound earthing system, which every SPD depends on.

LKS designs, installs and periodically tests surge protection and earthing for instrumentation sites in Malaysia. Speak to our engineers about a protection scheme or request a quotation.
