Regulated isolation transformer for AC voltage regulation in laboratories, testing fields, and service workshops, as the built-in isolation transformer ensures galvanic separation between the primary and secondary sides. Robust, stable metal housing and carrying handle for mobile use. Display instruments for current and voltage. Control lamp, fuse, circuit breaker, output via a socket (without protective contact). The display screens for current and voltage show the measurement values in true RMS as both analog and digital graphics, and feature a white backlight.
