Features: 1. Lightning strike, short circuit, anti-interference and good reliability; 2. The voltage regulation range is extremely wide; 3. Built-in power inserter; 4.5/8 hour standard seat, through joints; 5. Two-way output (each with power switch); 6. The self noise is small; 7. The installation method is flexible, convenient and firm. Technical Parameters: Voltage stability range: Input 175V ~ 250V full load output change ± 1% Input 160V ~ 280V full load output change ± 2% Load characteristics: From no load to full load, the output voltage changes ≤ 2% Short-circuit protection characteristics: When the load is short-circuited, the input current is 2.5 times that of full load. The output voltage is cut off within 0.1 hours, and the variator is not damaged. Operating environment: -40°C~+60°C Insulation characteristics: 1500V, no breakdown in 1 minute Output voltage: -60V±3 Output current: 2.2A, 3.2A, 4.2A, 6A, 10A, 15A (optional)
