Feature: - Brand new and high quality - Made of high quality material, durable - Built-in full-wave output bridge rectifier. - Voltage output increases with load. - Stable voltage output with negative voltage. - Overvoltage, overcurrent and short circuit protection. - Large manually adjustable voltage output range of -160V ~ 260V for 240V output. Specification: - Power: 2KW~3KW - Type: square, half circle (optional) - Color: mainly black - Capacitor: 250V 220uF - Material: plastic + wire + power supply - Maximum output: DC 90V 2.5A. - Excitation voltage: 90V - voltage: 16V20V - Frequency: 50/60Hz - Automatic pressure regulation accuracy: 1%. - Maximum temperature rise: 130C or 266F. - Continuous working time: 20 hours. - Suitable for Powerstroke / BlackMax generators from 2KW to 4KW Special Note: - Higher output AVRs are definitely suitable for generators with lower power outputs, conversely AVRs with lower power outputs cannot be used with higher power output generators. - If our AVR doesn't fit your alternator, manually turn the small bronze screw in the blue rubber part (potentiometer) clockwise or counterclockwise to achieve your desired power output. Turn clockwise to increase the voltage output, and turn counterclockwise to decrease the voltage output. If this does not help you, please for technical support. Package Included: 1 * voltage regulator (optional) Notes: 1. Due to various factors such as display brightness and light brightness, the actual color of the product may be slightly different from the website picture. 2. Please allow a slight deviation between the data and the manual measurement.
