Power supply PSX 40A - designed to operate in a single-phase AC network with a frequency of 50 (60) Hz with a voltage of 230V and is used to provide power supply with a stabilized voltage of 24V DC for various ship equipment. This product is equipped with an automatic shutdown of each of the 4 available outputs when the preset current is exceeded. The trip threshold is set by programming with a PC via RS422 interface. The power supply unit also has overload protection for the total output current consumption (total current consumption of all outputs) as in the analog version (total stabilization current 42A, in the event of a brief excess of the total current consumption above 42A),

The product is manufactured in a metal case with an existing grounding terminal. The casing has a bracket for mounting on a vertical bulkhead. On the front of the case there is a key switch for turning the unit on / off with a blue light indication, indicating the presence of the main power supply in the mode of operation of the power supply unit from the AC mains. Also on the front side there is a control panel with light indication (7 light indicators), which serves to display the operating modes of the power supply, including alarm signaling, and power supply controls, in the form of 4 buttons.
