Notes: * – When the input voltage drops below Umin, the fixed operation time of the device is 12 seconds, if the switches Umax and Umin are in the “ON” position. With any other combination of switches Umax and Umin, the device will operate after the delay time set by the User with Тoff(sec) control. If during this time (12 seconds) the mains parameters change, for example, at the maximum voltage, the device will operate at the smallest of the periods – after the delay time specified by the User, or after the time remaining of 12 seconds. ** – When working in “Maximum Voltage Control” mode, the ready time is 0.3 seconds. | |
