Rice Lake TP75 DC Transient Protector | Load Cell Surge Protection NEMA 4X
The Rice Lake TP75 DC Transient Protector is a compact, industrial-grade surge protection device designed to protect load cells, weighing indicators, and sensitive weighing electronics from damaging voltage transients, lightning-induced surges, and electrical disturbances. Engineered for truck scales, railroad scales, tank scales, bin scales, hopper scales, and other industrial weighing systems, the TP75 helps improve system reliability while reducing costly equipment damage and downtime.
Built with advanced avalanche diode technology, the TP75 delivers ultra-fast surge suppression with a response time of just five nanoseconds. This rapid reaction helps divert harmful voltage spikes away from connected equipment before damage can occur, making it ideal for installations exposed to unstable power conditions and outdoor environments.
The TP75 features full six-wire protection with a dedicated shield line, providing comprehensive protection for load cell circuits while maintaining signal integrity and weighing accuracy. The unit supports an unlimited number of parallel load cells and up to eight load cells connected in series, making it suitable for a wide range of weighing system configurations.
For demanding industrial environments, the TP75 is housed in a rugged impact-resistant polycarbonate enclosure rated NEMA Type 4X. The enclosure withstands washdown conditions up to 40 PSI and helps protect internal components from moisture, dust, and harsh environmental conditions. Two nylon strain-relief fittings provide secure cable entry and protection for field wiring installations.
Its compact footprint allows easy installation near load cells, junction boxes, or weighing indicators. Terminal lugs are included for straightforward wiring, and the unit can be used in both indoor and outdoor applications where dependable surge protection is essential. Whether protecting a truck scale, hopper scale, or process weighing system, the Rice Lake TP75 delivers reliable protection for critical weighing equipment.
