The PROMAX DT802 Control Module with Redundant Power Supply is the control module of the "Digital To TV" system, with a dual redundant power supply of 300 W and two inputs for 1 or 2 different electricity suppliers. Each power module is individually removable and hot-swappable. The redundant power supply works when either one of the electricity suppliers or one power module fails. In this case the second power module acts immediately without affecting the TV distribution system. Both power modules can be replaced by hot-swapping a new one, that is, without rebooting the system. This ensures the continuity for the TV distribution system. The power module has a warning system of light and a buzzer, which tells the user when there is a problem in the system.

All other DT-802 functions are equivalent to the power supply module DT-800 but more powerful: allows the specific control of each module and configuring all the parameters associated and can work in local mode via the front keypad or by remote control via an Ethernet connection.
