How to install the Bulgaria AC power supply so that it can function as a protection switch?(3)

The three-phase AC power intelligent protector has developed and created the function of "fault detection before closing", which has greatly improved its performance and reliability. The three-phase AC power intelligent protector detects the 24V input power supply voltage, the reverse connection of the neutral line, the disconnection of the neutral line, and the lack of phase/phase failure through the single-chip microcomputer before the main switch is closed.

During operation, it can track and detect the Bulgaria   24V input power supply voltage, neutral line disconnection, phase loss / disconnection, etc., and cut off the 24V input power supply in time when a fault occurs, making it safer and safer to use electricity. More reliable; at the same time, through a set of attached indicator lights, it shows the fault situation, which provides convenience for line maintenance.

(6) For the module power supply, some manufacturers have a fixed resistance directly connected to the adjustable terminal (ADJ) from the factory. When using, the user must configure a potentiometer with the corresponding resistance value to replace the fixed resistance. However, it should be noted that when the adjustable terminals are in an open state, loading is never allowed.
(7) In order to achieve sufficient heat dissipation, the module power supply should be installed in a location with better air convection. Generally, when the working current of the linear power supply is above 4A, or the working current of the switching power supply is above 7A, forced air cooling should be installed. In addition, no other items are allowed on the module power supply housing.
(8) The module power supply is generally suitable for resistive-based loads. If it needs to be applied to capacitive-based or inductive-based loads, it should be explained in the order contract in advance and customized by the manufacturer.

Bulgaria It can be widely used in electrical equipment protection stations, meteorological telemetry stations, energy pipeline telemetry stations, petroleum Exploration, automatic pumping and other places.
