Welcome to Veawe’s Surge Protective Devices (SPD) category, engineered to provide comprehensive transient voltage surge suppression (TVSS) for sensitive industrial electronics, control panels, and field instrumentation. In harsh industrial environments, lightning strikes, grid switching, and inductive load switching generate severe overvoltages that can instantly destroy expensive PLCs, I/O modules, serial communication ports, and analog sensors.
Veawe’s industrial-grade surge arresters are designed to divert high-energy surge currents safely to ground while clamping transient voltages to safe residual levels, ensuring uninterrupted uptime and maximum equipment longevity.
Power Line SPDs (AC & DC): High-capacity Type 1, Type 2, and Type 3 surge arresters designed for main switchboards, sub-distribution panels, 24V DC control power lines, and solar/battery power circuits.
Signal & Data Line SPDs: Low-capacitance surge protectors tailored for high-speed industrial serial buses (RS-485, RS-232, RS-422, Modbus), preserving data integrity while blocking induced transients.
Analog & Instrumentation SPDs: Ultra-fast response clamp modules designed to protect 4–20mA loops, 0–10V analog inputs/outputs, RTDs, and thermocouple circuits from ground potential shifts.
Key Features of Veawe Surge Protective Devices:
Multi-Stage Protection Architecture: Combining fast-acting Gas Discharge Tubes (GDT), Metal Oxide Varistors (MOV), and high-speed Transient Voltage Suppressors (TVS) for lightning-fast response times (<1 ns for data lines).
High Discharge Capacity: Robust ratings for nominal ($I_n$) and maximum ($I_{max}$) discharge currents capable of withstanding repetitive surge events.
DIN Rail Mountable Design: Space-efficient modular housings designed for straightforward, organized installation inside standard industrial enclosures and marshaling cabinets.
Status Indication & Remote Signaling: Visual status windows (Green/Red) and optional auxiliary fault-signaling contacts for predictive maintenance and remote alarm monitoring.
