Weighing System is a very common system in manufacturing plant & palm oil mills. However, such system often encounters sensitive equipment and device (Indicator) damages which lead to system shutting down due to direct and indirect effect of lightning occurrence. Implementation of surge protective device, SPD and proper earthing system must be constructed to protect against the coupling effect created by the lightning direct and indirect strike.

PROMOV TD1 series signal level SPD has a compact design and specialized in protecting sensitive equipment which operate in various DC voltages for input and output signal. It comes with a LED indicator which will turn on when the SPD is malfunction or damaged. The SPD has the capability of withstanding 1kA (10/350us) lightning impulse current and 10kA (8.20us) lightning discharge current.

As for localized power, PROMOV TPS series low voltage SPD comes with overvoltage, undervoltage and surges 3 in 1 protection to protect the system from the transient overvoltage and lightning discharge current.
