Feature: 1. MULTI FUNCTION: Can be used for voltage regulation, speed regulation, temperature regulation, dimming, versatile and powerful 2. SIMPLE PUSH BUTTON ADJUSTMENT: Electronic voltage regulator support push button adjustment, possess high stability and easy operation 3. VARIOUS PROTECTION: No lag, no delay, with peak voltage absorption circuit to effectively protect high power thyristor non surge, non spike, RC absorption multiple protection 4. VOLTAGE REGULATION RANGE: Support 0‑ steplessly adjustable (under load conditions), truly buck to 0V, boost from 0V 5. STABLE AND DURABLE: Electronic voltage regulator come with stable structure, excellent performance and long service life Specification: Rated Current: 25A Maximum Current: 45A (resistive load limit power, 5000W recommended for long term heating) Controllable Model: BTA100-800B (imported) STMicroelectronics. Package List: 1 x Electronic Voltage Regulator Note: 1. The output voltage is the same as the input voltage when there is no load, and the output voltage can only be measured when a load of more than 30W is connected.2. Input AC, the output is also AC, not DC.3. The 10000W mentioned above refers to the power when working on a resistive load. The inductive load is 1/3 of the resistive load. The resistive load refers to lamps, heating wires, etc., and the inductive load refers to series excitation motors.4. For electrical appliances with metal casings, please ground them safely.
