UniWave Electric
High-reliability solid state relays, vacuum circuit breakers, and industrial control components compliant with global safety standards.
In modern electrical engineering, electrical isolation is not merely a safety protocol; it is the core architecture that ensures signal integrity and equipment longevity. An isolation relay prevents the flow of dangerous high-voltage currents between different sections of a circuit while allowing control signals to pass seamlessly. By utilizing electromagnetic fields, light waves (in optocouplers), or solid-state semiconductors, isolation relays break the direct conduction path (galvanic isolation), neutralizing ground loop problems and blocking transient voltage spikes.
Utilizes physical separation via induction. The primary coil generates a magnetic field across a physical air gap to actuate contacts on the secondary side, providing exceptional dielectric strength and isolation levels up to several kilovolts.
Combines an LED on the input side with a photosensitive semiconductor on the output side. This eliminates mechanical wear, enables microsecond switching speeds, and ensures zero electromagnetic interference (EMI).
Engineered to withstand extreme lightning surges, high transient voltages (dv/dt), and static discharges. Essential for rugged industrial automation and grid interfaces.

Deploying advanced isolation technologies across key vertical markets to guarantee system resilience.
In photovoltaic (PV) solar inverters and battery energy storage systems (BESS), isolation relays provide secure physical separation between high-voltage DC battery packs and low-voltage control circuits. This prevents thermal runaway scenarios and ensures precise monitoring of ground insulation resistance.
DC fast-charging stations (Level 3) operate at voltages ranging from 400V to 1000V. High-voltage isolation relays monitor insulation status and isolate the vehicle battery in real-time if a fault is detected, protecting the end-user and station equipment.
PLC (Programmable Logic Controller) I/O modules require absolute galvanic separation to prevent inductive load switching surges from feeding back into the processing unit. Our isolation relays prevent control room downtime caused by motor startups or solenoid operations.

An isolation relay provides physical separation (galvanic isolation) between high-voltage power components and sensitive, low-voltage control circuits. By severing the direct electrical conduction pathway, it protects controllers (such as PLCs) from high-voltage spikes, isolates faults, and eliminates ground loops.
All low-voltage products and relays manufactured by Wenzhou UniWave Electric strictly adhere to international IEC/EN standards. Our products have received recognized certifications including SAA, CE, CB, and our factory maintains ISO9001 quality management standard compliance.
SSRs provide superior switching speeds, zero acoustic noise, and extended lifespans because they contain no moving parts. However, electromechanical relays are still preferred in applications requiring complete physical gap isolation, low contact resistance, and immunity to high thermal environments.
Liushi is home to an integrated vertical supply chain cluster. This cluster brings together raw material sourcing, precision tooling design, and automated assembly in one location, reducing lead times and ensuring competitive, factory-direct wholesale pricing.
