Essential details：R911268888 TVD Supply Modules REXROTH

TVD 1.3-15-03 by Rexroth, Indramat, Bosch in the TVD Series. The TVD power supply module provides DC power for Indramat drives, which work with Indramat controls and servo motors. The TVD 1.3 is equipped with extensive monitoring functions as well. This TVD 1.3-15-03 offers a DC Bus Cont. Power of 15 kW and a DC Bus Voltage of 320V, along with a Series number of 1 and a Design number of 3.

What is the power module?
Power supply modules are power supplies that can be mounted directly on the printed circuit board. They are available in step-down and step-up formats, and provide power for application-specific integrated circuits (ASics), digital signal processors (DSPS), microprocessors, memory, field programmable gate arrays (FPgas), and other digital or analog loads.

2. DC/DC power module
DC-DC is implemented with the idea of switching power supply. DC-DC has two types of buck and boost, here called buck. For example, enter 10V in DC-DC. The DC-DC has an internal oscillator and chopper module. For example, one time range allows 10V to pass, and the other time range does not allow 10V to pass (equal to 0v).

On the other hand, if there is a capacitor at the output, and the capacitor is large enough, the result is a calculus of the pulse waveform in the middle, and the output is a DC waveform of 5V. Compared with the constant voltage module, the process of the step-down module to a greater extent to avoid the power consumption on the step-down module, the internal oscillation part by controlling its duty cycle, the output is constant (for example, in a DC-DC, the input range is 6V to 16V, the output is 5V, in the input range, the output is 5v, the error is only a few tenths of a volt. In addition, the output of the stability module has a certain linear relationship with the input voltage, and the output voltage difference between the input 7V and the input 14V is relatively large.

Three, the use of power module advantages
There are now many different Psus sold by different vendors in the market, but it is better to import Psus by product than to integrate solutions, because adopting Psus can save development time and bring products to market faster.

The power module also has the following advantages:

Each unit can be rigorously tested individually to ensure a highly reliable product, including power-on testing to exclude products that do not meet specifications. In contrast, integrated solutions are difficult to test because the entire power system works closely with other functional systems on the circuit.
Different suppliers can design modules of the same size according to existing technical standards, providing a variety of options for engineers designing power supplies.
The modules are designed and tested in accordance with standard performance regulations, so the risks can be reduced by adopting new technologies.
If an integrated solution is used, the entire motherboard needs to be replaced when the power supply system fails. If a modular design is used, only the faulty module can be replaced, thus saving costs and development time.
