Type de relais Stabilisateur de tension

Relay-type voltage regulators achieve graded adjustment and regulation of the output voltage by rapidly switching the taps of the autotransformer through relay control or CPU-controlled switches. 1. Utilizes CPU or relay logic to control different tap contacts; 2. The output voltage is adjusted in steps within a preset range to control it at the target value; 3. May include auxiliary functions such as display and time-delay protection;

✔ Wide input voltage range: Supports multiple input voltage levels (e.g., 100–260VAC, 120–250VAC), automatically identifying and regulating the output voltage to a safe range when the power grid is unstable. ✔ Excellent protection performance: Many models are equipped with overvoltage, undervoltage, overload, and short-circuit protection, as well as start-up delay, display monitoring, and other functions, comprehensively protecting the safe operation of connected equipment. ✔ Wide range of models covering various applications: Power factor matching from 0.5 KVA to 45 KVA meets the voltage regulation needs of everything from personal computers and home appliances to office equipment and small machines. ✔ Simple, reliable, and low maintenance cost: Low-relay and CPU control logic reduces complex mechanical parts, lowers maintenance difficulty, and extends service life.

1. Intuitive and reliable working principle: The relay, in conjunction with an automatic control circuit, detects input fluctuations and switches taps to maintain a stable output voltage. 2. More cost-effective: Compared to servo regulators, relay-type solutions are more economical and suitable for general applications where accuracy and noise are not extremely sensitive. 3. Easy to install and maintain: The category page explicitly emphasizes its ease of installation and maintenance, making it suitable for large-scale projects and rapid deployment by channel customers. 4. Wide application coverage: Applications include residential, commercial, industrial, agricultural, and telecommunications scenarios (such as home appliances, office equipment, control cabinets, pumps, base station equipment, etc.). 5. Predictable "relay noise/range fluctuations": Relay operation will produce "clicking/buzzing noise," and it is noted that its range adjustment is slightly inferior to servo regulators in terms of accuracy and noise, but it wins in terms of simplicity and cost-effectiveness.
