Essential details：TVD1.3-15-03 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.

1. What is the power module?
Psus are power supplies that can be installed directly on the printed circuit board. There are step-down and step-up types. They provide power for 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 realized with the idea of switching power supply. DC-DC has two kinds of depressurization and booster, which is called depressurization. For example, enter 10V in DC-DC. The DC-DC has an internal oscillator and chopper module. For example, 10V is allowed to pass in one time segment and 10V is not allowed to pass in another time segment (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, output 5V DC waveform. Compared with the constant-voltage module, the step-down process avoids the power consumption on the step-down module to a greater extent. By controlling its duty cycle, the internal oscillation section has a constant output (for example, in a DC-DC, the input range is 6V to 16V, the output is 5V, and in the input range, the output is 5v, with an error of only a few tenths of a volt. In addition, the output of the stability module has a certain linear relationship with the input voltage, the output voltage of the input 7V and the output voltage of the input 14V is relatively large difference.

Three, the advantages of the power module
There are many different Psus in the market today from different vendors, but importing Psus by product is better than an integrated solution, as adopting Psus saves development time and brings the product to market faster.

The power module also has the following advantages:

Each unit can be rigorously tested individually to ensure high reliability products, 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 the specifications of standard performance, so the exposure to risk can be reduced through the adoption of new technologies.
If the integrated solution is used, the entire mainboard needs to be replaced when the power supply system fails. If you use a modular design, you can simply replace the faulty module, thus saving cost and development time.
